parts 550 through 582 require the lessee 

to meet a requirement or perform an 

action, the lessee, operator (if one has 

been designated), and the person actually performing the activity to which 

the requirement applies are jointly and 

severally responsible for complying 

with the regulation. 

NAMING AND IDENTIFYING FACILITIES

AND WELLS (DOES NOT INCLUDE MODUS) 

§ 250.150 How do I name facilities and 

wells in the Gulf of Mexico Region? 

(a) Assign each facility a letter designation except for those types of facilities identified in paragraph (c)(1) of 

this section. For example, A, B, CA, or 

CB. 

(1) After a facility is installed, rename each predrilled well that was assigned only a number and was suspended temporarily at the mudline or 

at the surface. Use a letter and number 

designation. The letter used must be 

the same as that of the production facility, and the number used must correspond to the order in which the well 

was completed, not necessarily the 

number assigned when it was drilled. 

For example, the first well completed 

for production on Facility A would be 

renamed Well A–1, the second would be 

Well A–2, and so on; and 

(2) When you have more than one facility on a block, each facility installed, and not bridge-connected to 

another facility, must be named using 

a different letter in sequential order. 

For example, EC 222A, EC 222B, EC 

222C. 

(3) When you have more than one facility on multiple blocks in a local 

area being co-developed, each facility 

installed and not connected with a 

walkway to another facility should be 

named using a different letter in sequential order with the block number 

corresponding to the block on which 

the platform is located. For example, 

EC 221A, EC 222B, and EC 223C. 

(b) In naming multiple well caissons, 

you must assign a letter designation. 

(c) In naming single well caissons, 

you must use certain criteria as follows: 

(1) For single well caissons not attached to a facility with a walkway, 

use the well designation. For example, 

Well No. 1; 

(2) For single well caissons attached 

to a facility with a walkway, use the 

same designation as the facility. For 

example, rename Well No.10 as A–10; 

and 

(3) For single well caissons with production equipment, use a letter designation for the facility name and a 

letter plus number designation for the 

well. For example, the Well No. 1 caisson would be designated as Facility A, 

and the well would be Well A–1. 

§ 250.151 How do I name facilities in 

the Pacific Region? 

The operator assigns a name to the 

facility. 

§ 250.152 How do I name facilities in 

the Alaska Region? 

Facilities will be named and identified according to the Regional Director’s directions. 

§ 250.153 Do I have to rename an existing facility or well? 

You do not have to rename facilities 

installed and wells drilled before January 27, 2000, unless the Regional Director requires it. 

§ 250.154 What identification signs 

must I display? 

(a) You must identify all facilities, 

artificial islands, and mobile offshore 

drilling units with a sign maintained in 

a legible condition. 

(1) You must display an identification sign that can be viewed from the 

waterline on at least one side of the 

platform. The sign must use at least 3- 

inch letters and figures. 

(2) When helicopter landing facilities 

are present, you must display an additional identification sign that is visible 

from the air. The sign must use at 

least 12-inch letters and figures and 

must also display the weight capacity 

of the helipad unless noted on the top 

of the helipad. If this sign is visible to 

both helicopter and boat traffic, then 


Lhorne on DSK5TPTVN1PROD with CFR
67 

Safety & Environmental Enforcement, Interior § 250.171 

the sign in paragraph (a)(1) of this section is not required. 

(3) Your identification sign must: 

(i) List the name of the lessee or designated operator; 

(ii) In the GOM OCS Region, list the 

area designation or abbreviation and 

the block number of the facility location as depicted on OCS Official Protraction Diagrams or leasing maps; 

(iii) In the Pacific OCS Region, list 

the lease number on which the facility 

is located; and 

(iv) List the name of the platform, 

structure, artificial island, or mobile 

offshore drilling unit. 

(b) You must identify singly completed wells and multiple completions 

as follows: 

(1) For each singly completed well, 

list the lease number and well number 

on the wellhead or on a sign affixed to 

the wellhead; 

(2) For wells with multiple completions, downhole splitter wells, and multilateral wells, identify each completion in addition to the well name and 

lease number individually on the well 

flowline at the wellhead; and 

(3) For subsea wells that flow individually into separate pipelines, affix the 

required sign on the pipeline or surface 

flowline dedicated to that subsea well 

at a convenient location on the receiving platform. For multiple subsea wells 

that flow into a common pipeline or 

pipelines, no sign is required. 

§§ 250.160–250.167 [Reserved] 

SUSPENSIONS

§ 250.168 May operations or production be suspended? 

(a) You may request approval of a 

suspension, or the Regional Supervisor 

may direct a suspension (Directed Suspension), for all or any part of a lease 

or unit area. 

(b) Depending on the nature of the 

suspended activity, suspensions are labeled either Suspensions of Operations 

(SOO) or Suspensions of Production 

(SOP). 

§ 250.169 What effect does suspension 

have on my lease? 

(a) A suspension may extend the 

term of a lease (see §250.180(b), (d), and 

(e)). The extension is equal to the 

length of time the suspension is in effect, except as provided in paragraph 

(b) of this section. 

(b) A Directed Suspension does not 

extend the term of a lease when the Regional Supervisor directs a suspension 

because of: 

(1) Gross negligence; or 

(2) A willful violation of a provision 

of the lease or governing statutes and 

regulations. 

§ 250.170 How long does a suspension 

last? 

(a) BSEE may issue suspensions for 

up to 5 years per suspension. The Regional Supervisor will set the length of 

the suspension based on the conditions 

of the individual case involved. BSEE 

may grant consecutive suspension periods. 

(b) An SOO ends automatically when 

the suspended operation commences. 

(c) An SOP ends automatically when 

production begins. 

(d) A Directed Suspension normally 

ends as specified in the letter directing 

the suspension. 

(e) BSEE may terminate any suspension when the Regional Supervisor determines the circumstances that justified the suspension no longer exist or 

that other lease conditions warrant 

termination. The Regional Supervisor 

will notify you of the reasons for termination and the effective date. 

§ 250.171 How do I request a suspension? 

You must submit your request for a 

suspension to the Regional Supervisor, 

and BSEE must receive the request before the end of the lease term (i.e., end 

of primary term, end of the 180-day period following the last leaseholding operation, and end of a current suspension). Your request must include: 

(a) The justification for the suspension including the length of suspension 

requested; 

(b) A reasonable schedule of work 

leading to the commencement or restoration of the suspended activity; 

(c) A statement that a well has been 

drilled on the lease and determined to 

be producible according to §250.1603 

(SOP only), 30 CFR 550.115, or 30 CFR 

550.116; 


Lhorne on DSK5TPTVN1PROD with CFR
68 

§ 250.172 30 CFR Ch. II (7–1–15 Edition) 

(d) A commitment to production 

(SOP only); and 

(e) The service fee listed in §250.125 of 

this subpart. 

§ 250.172 When may the Regional Supervisor grant or direct an SOO or 

SOP? 

The Regional Supervisor may grant 

or direct an SOO or SOP under any of 

the following circumstances: 

(a) When necessary to comply with 

judicial decrees prohibiting any activities or the permitting of those activities. The effective date of the suspension will be the effective date required 

by the action of the court; 

(b) When activities pose a threat of 

serious, irreparable, or immediate 

harm or damage. This would include a 

threat to life (including fish and other 

aquatic life), property, any mineral deposit, or the marine, coastal, or human 

environment. BSEE may require you to 

do a site-specific study (see §250.177(a)). 

(c) When necessary for the installation of safety or environmental protection equipment; 

(d) When necessary to carry out the 

requirements of NEPA or to conduct an 

environmental analysis; or 

(e) When necessary to allow for inordinate delays encountered in obtaining 

required permits or consents, including 

administrative or judicial challenges 

or appeals. 

§ 250.173 When may the Regional Supervisor direct an SOO or SOP? 

The Regional Supervisor may direct 

a suspension when: 

(a) You failed to comply with an applicable law, regulation, order, or provision of a lease or permit; or 

(b) The suspension is in the interest 

of National security or defense. 

§ 250.174 When may the Regional Supervisor grant or direct an SOP? 

The Regional Supervisor may grant 

or direct an SOP when the suspension 

is in the National interest, and it is 

necessary because the suspension will 

meet one of the following criteria: 

(a) It will allow you to properly develop a lease, including time to construct and install production facilities; 

(b) It will allow you time to obtain 

adequate transportation facilities; 

(c) It will allow you time to enter a 

sales contract for oil, gas, or sulphur. 

You must show that you are making an 

effort to enter into the contract(s); or

that would result in premature abandonment of a producing well(s). 

§ 250.175 When may the Regional Supervisor grant an SOO? 

(a) The Regional Supervisor may 

grant an SOO when necessary to allow 

you time to begin drilling or other operations when you are prevented by 

reasons beyond your control, such as 

unexpected weather, unavoidable accidents, or drilling rig delays. 

(b) The Regional Supervisor may 

grant an SOO when all of the following 

conditions are met: 

(1) The lease was issued with a primary lease term of 5 years, or with a 

primary term of 8 years with a requirement to drill within 5 years; 

(2) Before the end of the third year of

Lhorne on DSK5TPTVN1PROD with CFR
70 

§§ 250.181–250.185 30 CFR Ch. II (7–1–15 Edition) 

whenever production resumes during 

the last 180 days of the primary term. 

(2) Your lease expires at the end of 

its primary term unless you are conducting operations on your lease (see 30 

CFR part 556). For purposes of this section, the term operations means, drilling, well-reworking, or production in 

paying quantities. The objective of the 

drilling or well-reworking must be to 

establish production in paying quantities on the lease. 

(b) If you stop conducting operations 

during the last 180 days of your primary lease term, your lease will expire 

unless you either resume operations or 

receive an SOO or an SOP from the Regional Supervisor under §250.172, 

§250.173, §250.174, or §250.175 before the 

end of the 180th day after you stop operations. 

(c) If you extend your lease term 

under paragraph (b) of this section, you 

must pay rental or minimum royalty, 

as appropriate, for each year or part of 

the year during which your lease continues in force beyond the end of the 

primary lease term. 

(d) If you stop conducting operations 

on a lease that has continued beyond 

its primary term, your lease will expire 

unless you resume operations or receive an SOO or an SOP from the Regional Supervisor under §250.172,

end of the 180th day after you stop operations. 

(e) You may ask the Regional Supervisor to allow you more than 180 days 

to resume operations on a lease continued beyond its primary term when operating conditions warrant. The request must be in writing and explain 

the operating conditions that warrant 

a longer period. In allowing additional 

time, the Regional Supervisor must determine that the longer period is in the 

National interest, and it conserves resources, prevents waste, or protects 

correlative rights. 

(f) When you begin conducting operations on a lease that has continued 

beyond its primary term, you must immediately notify the District Manager 

either orally or by fax or e-mail and 

follow up with a written report according to paragraph (g) of this section. 

(g) If your lease is continued beyond 

its primary term, you must submit a 

report to the District Manager under 

paragraphs (h) and (i) of this section 

whenever production begins initially, 

whenever production ceases, whenever

days after the first full month of zero 

production. 

(3) Resumption of production—within 

5 days of resuming production after 

ceasing production under paragraph 

(i)(2) of this section. 

(4) Drilling or well reworking operations—within 5 days of beginning and 

completing the leaseholding operations. 

(j) For leases continued beyond the 

primary term, you must immediately 

report to the District Manager if operations do not begin before the end of 

the 180-day period. 

§§ 250.181–250.185 [Reserved]

1348(d)(1) and (2)) is a fact-finding proceeding with no adverse parties. The 

purpose of the investigation is to prepare a public report that determines 

the cause or causes of the incident. The 

investigation may involve panel meetings conducted by a chairperson appointed by BSEE. The following requirements apply to any panel meetings involving persons giving testimony: 

(a) A person giving testimony may 

have legal or other representative(s) 

present to provide advice or counsel 

while the person is giving testimony. 

The chairperson may require a verbatim transcript to be made of all oral 

testimony. The chairperson also may 

accept a sworn written statement in 

lieu of oral testimony. 

(b) Only panel members, and any experts the panel deems necessary, may 

address questions to any person giving 

testimony. 

(c) The chairperson may issue subpoenas to persons to appear and provide testimony or documents at a panel 

meeting. A subpoena may not require a 

person to attend a panel meeting held 

at a location more than 100 miles from 

where a subpoena is served. 

(d) Any person giving testimony may 

request compensation for mileage, and 


Lhorne on DSK5TPTVN1PROD with CFR
73

CASING AND CEMENTING REQUIREMENTS

§ 250.420 What well casing and cementing requirements must I meet? 

You must case and cement all wells. 

Your casing and cementing programs 

must meet the requirements of this 

section and of §§250.421 through 250.428. 

(a) Casing and cementing program requirements. Your casing and cementing 

programs must: 

(1) Properly control formation pressures and fluids; 

(2) Prevent the direct or indirect release of fluids from any stratum 

through the wellbore into offshore 

waters; 

(3) Prevent communication between 

separate hydrocarbon-bearing strata; 

(4) Protect freshwater aquifers from 

contamination; 

(5) Support unconsolidated sediments; and 

(6)(i) Include a certification signed by 

a registered professional engineer that 

the casing and cementing design is appropriate for the purpose for which it is 

intended under expected wellbore conditions, and is sufficient to satisfy the 

tests and requirements of this section 

and §250.423. Submit this certification 

with your APD (Form BSEE–0123). 

(ii) You must have the registered professional engineer involved in the casing and cementing design process. 

(iii) The registered professional engineer must be registered in a state of 

the United States and have sufficient 

expertise and experience to perform 

the certification. 

(b) Casing requirements. (1) You must 

design casing (including liners) to 

withstand the anticipated stresses imposed by tensile, compressive, and 

buckling loads; burst and collapse pressures; thermal effects; and combinations thereof. 

(2) The casing design must include 

safety measures that ensure well control during drilling and safe operations 

during the life of the well. 

(3) On all wells that use subsea BOP 

stacks, you must include two independent barriers, including one mechanical barrier, in each annular flow 

path (examples of barriers include, but 

are not limited to, primary cement job 

and seal assembly). For the final casing 

string (or liner if it is your final 

string), you must install one mechanical barrier in addition to cement to 

prevent flow in the event of a failure in 

the cement. A dual float valve, by 

itself, is not considered a mechanical 

barrier. These barriers cannot be modified prior to or during completion or 

abandonment operations. The BSEE 

District Manager may approve alternative options under §250.141. You must 

submit documentation of this installation to BSEE in the End-of-Operations 

Report (Form BSEE–0125). 

(c) Cementing requirements. You must 

design and conduct your cementing 

jobs so that cement composition, 

placement techniques, and waiting 


Lhorne on DSK5TPTVN1PROD with CFR
97 

Safety & Environmental Enforcement, Interior § 250.422 

times ensure that the cement placed 

behind the bottom 500 feet of casing attains a minimum compressive strength 

of 500 psi before drilling out of the casing or before commencing completion 

operations.

FR 50892, Aug. 22, 2012] 

§ 250.421 What are the casing and cementing requirements by type of 

casing string? 

The table in this section identifies 

specific design, setting, and cementing 

requirements for casing strings and liners. For the purposes of subpart D, the 

casing strings in order of normal installation are as follows: drive or structural, conductor, surface, intermediate, 

and production casings (including liners). The District Manager may approve or prescribe other casing and cementing requirements where appropriate. 

Casing type Casing requirements Cementing requirements 

(a) Drive or Structural ..... Set by driving, jetting, or drilling to the minimum 

depth as approved or prescribed by the District Manager.

If you drilled a portion of this hole, you must use 

enough cement to fill the annular space back 

to the mudline. 

(b) Conductor .................. Design casing and select setting depths based 

on relevant engineering and geologic factors. 

These factors include the presence or absence of hydrocarbons, potential hazards, and 

water depths; 

Set casing immediately before drilling into formations known to contain oil or gas. If you encounter oil or gas or unexpected formation 

pressure before the planned casing point, you 

must set casing immediately.

Use enough cement to fill the calculated annular 

space back to the mudline. 

Verify annular fill by observing cement returns. If 

you cannot observe cement returns, use additional cement to ensure fill-back to the 

mudline. 

For drilling on an artificial island or when using a 

well cellar, you must discuss the cement fill 

level with the District Manager. 

(c) Surface ....................... Design casing and select setting depths based 

on relevant engineering and geologic factors. 

These factors include the presence or absence of hydrocarbons, potential hazards, and 

water depths.

Use enough cement to fill the calculated annular 

space to at least 200 feet inside the conductor 

casing. 

When geologic conditions such as near-surface 

fractures and faulting exist, you must use 

enough cement to fill the calculated annular 

space to the mudline. 

(d) Intermediate ............... Design casing and select setting depth based on 

anticipated or encountered geologic characteristics or wellbore conditions.

Use enough cement to cover and isolate all hydrocarbon-bearing zones and isolate abnormal 

pressure intervals from normal pressure intervals in the well. 

As a minimum, you must cement the annular 

space 500 feet above the casing shoe and 

500 feet above each zone to be isolated. 

(e) Production .................. Design casing and select setting depth based on 

anticipated or encountered geologic characteristics or wellbore conditions.

Use enough cement to cover or isolate all hydrocarbon-bearing zones above the shoe. 

As a minimum, you must cement the annular 

space at least 500 feet above the casing shoe 

and 500 feet above the uppermost hydrocarbon-bearing zone. 

(f) Liners .......................... If you use a liner as conductor or surface casing, 

you must set the top of the liner at least 200 

feet above the previous casing/liner shoe.

If you use a liner as an intermediate string below 

a surface string or production casing below an 

intermediate string, you must set the top of the 

liner at least 100 feet above the previous casing shoe.

Same as cementing requirements for specific 

casing types. For example, a liner used as intermediate casing must be cemented according to the cementing requirements for intermediate casing. 

§ 250.422 When may I resume drilling 

after cementing? 

(a) After cementing surface, intermediate, or production casing (or liners), you may resume drilling after the 

cement has been held under pressure 

for 12 hours. For conductor casing, you 

may resume drilling after the cement 

has been held under pressure for 8 

hours. One acceptable method of holding cement under pressure is to use 

float valves to hold the cement in 

place. 

(b) If you plan to nipple down your 

diverter or BOP stack during the 8- or 


Lhorne on DSK5TPTVN1PROD with CFR
98 

§ 250.423 30 CFR Ch. II (7–1–15 Edition) 

12-hour waiting time, you must determine, before nippling down, when it 

will be safe to do so. You must base 

your determination on a knowledge of 

formation conditions, cement composition, effects of nippling down, presence 

of potential drilling hazards, well conditions during drilling, cementing, and 

post cementing, as well as past experience. 

§ 250.423 What are the requirements 

for pressure testing casing? 

(a) The table in this section describes 

the minimum test pressures for each 

string of casing. You may not resume 

drilling or other down-hole operations 

until you obtain a satisfactory pressure test. If the pressure declines more 

than 10 percent in a 30-minute test, or 

if there is another indication of a leak, 

you must investigate the cause and receive approval from the appropriate 

BSEE District Manager for the repair 

to resolve the problem ensuring that 

the casing will provide a proper seal. 

The BSEE District Manager may approve or require other casing test pressures. 

Casing type Minimum test 

pressure 

(1) Drive or Structural ............ Not required. 

(2) Conductor ......................... 200 psi. 

(3) Surface, Intermediate, and 

Production.

70 percent of its minimum internal yield. 

(b) You must ensure proper installation of casing in the subsea wellhead or 

liner in the liner hanger. 

(1) You must ensure that the latching 

mechanisms or lock down mechanisms 

are engaged upon installation of each 

casing string. 

(2) If you run a liner that has a latching mechanism or lock down mechanism, you must ensure that the latching mechanisms or lock down mechanisms are engaged upon installation of 

the liner. 

(3) You must perform a pressure test 

on the casing seal assembly to ensure 

proper installation of casing or liner. 

You must perform this test for the intermediate and production casing 

strings or liner. 

(i) You must submit for approval 

with your APD, test procedures and 

criteria for a successful test. 

(ii) You must document all your test 

results and make them available to 

BSEE upon request. 

(c) You must perform a negative 

pressure test on all wells that use a 

subsea BOP stack or wells with 

mudline suspension systems. The BSEE 

District Manager may require you to 

perform additional negative pressure 

tests on other casing strings or liners 

(e.g., intermediate casing string or 

liner) or on wells with a surface BOP 

stack. 

(1) You must perform a negative pressure test on your final casing string or 

liner. 

(2) You must perform a negative test 

prior to unlatching the BOP at any 

point in the well. The negative test 

must be performed on those components, at a minimum, that will be exposed to the negative differential pressure that will occur when the BOP is 

disconnected. 

(3) You must submit for approval 

with your APD, test procedures and 

criteria for a successful test. If any of 

your test procedures or criteria for a 

successful test change, you must submit for approval the changes in a revised APD or APM. 

(4) You must document all your test 

results and make them available to 

BSEE upon request. 

(5) If you have any indication of a 

failed negative pressure test, such as, 

but not limited to pressure buildup or 

observed flow, you must immediately 

investigate the cause. If your investigation confirms that a failure occurred during the negative pressure 

test, you must: 

(i) Correct the problem and immediately contact the appropriate BSEE 

District Manager. 

(ii) Submit a description of the corrective action taken and you must receive approval from the appropriate 

BSEE District Manager for the retest. 

(6) You must have two barriers in 

place, as required in §250.420(b)(3), prior

liner (and liner-lap) to a minimum of 

500 psi above the formation fracture 

pressure at the casing shoe into which 

the liner is lapped. 

(c) You may not resume drilling or 

other down-hole operations until you 

obtain a satisfactory pressure test. If 

the pressure declines more than 10 percent in a 30-minute test or if there is 

another indication of a leak, you must 

re-cement, repair the liner, or run additional casing/liner to provide a proper 

seal. 

§ 250.426 What are the recordkeeping 

requirements for casing and liner 

pressure tests? 

You must record the time, date, and 

results of each pressure test in the 

driller’s report maintained under 

standard industry practice. In addition, 

you must record each test on a pressure chart and have your onsite representative sign and date the test as 

being correct. 

§ 250.427 What are the requirements 

for pressure integrity tests? 

You must conduct a pressure integrity test below the surface casing or 

liner and all intermediate casings or 

liners. The District Manager may require you to run a pressure-integrity 

test at the conductor casing shoe if 

warranted by local geologic conditions 

or the planned casing setting depth. 

You must conduct each pressure integrity test after drilling at least 10 feet 

but no more than 50 feet of new hole 

below the casing shoe. You must test 

to either the formation leak-off pressure or to an equivalent drilling fluid 

weight if identified in an approved 

APD. 

(a) You must use the pressure integrity test and related hole-behavior observations, such as pore-pressure test 

results, gas-cut drilling fluid, and well 

kicks to adjust the drilling fluid program and the setting depth of the next 

casing string. You must record all test 

results and hole-behavior observations 

made during the course of drilling related to formation integrity and pore 

pressure in the driller’s report. 

(b) While drilling, you must maintain 

the safe drilling margin identified in 

the approved APD. When you cannot 

maintain this safe margin, you must 

suspend drilling operations and remedy 

the situation. 

§ 250.428 What must I do in certain cementing and casing situations? 

The table in this section describes actions that lessees must take when certain situations occur during casing and 

cementing activities. 

If you encounter the following situation: Then you must . . . 

(a) Have unexpected formation pressures or conditions that 

warrant revising your casing design, 

Submit a revised casing program to the District Manager for 

approval.

intervals, 

Isolate those intervals from normal pressures by squeeze cementing before you complete; suspend operations; or abandon the well, whichever occurs first. 

(f) Decide to produce a well that was not originally contemplated for production, Have at least two cemented casing strings (does not include 

liners) in the well. Note: All producing wells must have at 

least two cemented casing strings. 

(g) Want to drill a well without setting conductor casing, Submit geologic data and information to the District Manager 

that demonstrates the absence of shallow hydrocarbons or 

hazards. This information must include logging and drilling 

fluid-monitoring from wells previously drilled within 500 feet 

of the proposed well path down to the next casing point. 

(h) Need to use less than required cement for the surface casing during floating drilling operations to provide protection 

from burst and collapse pressures, 

Submit information to the District Manager that demonstrates 

the use of less cement is necessary. 

(i) Cement across a permafrost zone, Use cement that sets before it freezes and has a low heat of 

hydration.

of the hole are not greater than the 

test pressures for the previous BOP 

test. You must indicate in your APD 

which casing strings and liners meet 

these criteria. 

§ 250.448 What are the BOP pressure 

tests requirements? 

When you pressure test the BOP system, you must conduct a low-pressure 

and a high-pressure test for each BOP 

component. You must conduct the lowpressure test before the high-pressure 

test. Each individual pressure test 

must hold pressure long enough to 

demonstrate that the tested component(s) holds the required pressure. Required test pressures are as follows: 

(a) Low-pressure test. All low-pressure 

tests must be between 200 and 300 psi. 

Any initial pressure above 300 psi must 

be bled back to a pressure between 200 

and 300 psi before starting the test. If 

the initial pressure exceeds 500 psi, you 

must bleed back to zero and reinitiate 

the test. 

(b) High-pressure test for ram-type 

BOPs, the choke manifold, and other 

BOP components. The high-pressure test 

must equal the rated working pressure 

of the equipment or be 500 psi greater 

than your calculated maximum anticipated surface pressure (MASP) for the 

applicable section of hole. Before you 

may test BOP equipment to the MASP 

plus 500 psi, the District Manager must 

have approved those test pressures in 

your APD. 

(c) High pressure test for annular-type 

BOPs. The high pressure test must 

equal 70 percent of the rated working 

pressure of the equipment or to a pressure approved in your APD. 

(d) Duration of pressure test. Each test 

must hold the required pressure for 5 


Lhorne on DSK5TPTVN1PROD with CFR
105 

Safety & Environmental Enforcement, Interior § 250.450 

minutes. However, for surface BOP systems and surface equipment of a subsea 

BOP system, a 3-minute test duration 

is acceptable if you record your test 

pressures on the outermost half of a 4- 

hour chart, on a 1-hour chart, or on a 

digital recorder. If the equipment does 

not hold the required pressure during a 

test, you must correct the problem and 

retest the affected component(s).

DRILLING FLUID REQUIREMENTS

§ 250.455 What are the general requirements for a drilling fluid program? 

You must design and implement your 

drilling fluid program to prevent the 

loss of well control. This program must 

address drilling fluid safe practices, 

testing and monitoring equipment, 

drilling fluid quantities, and drilling 

fluid-handling areas. 

§ 250.456 What safe practices must the 

drilling fluid program follow? 

Your drilling fluid program must include the following safe practices: 

(a) Before starting out of the hole 

with drill pipe, you must properly condition the drilling fluid. You must circulate a volume of drilling fluid equal 

to the annular volume with the drill 

pipe just off-bottom. You may omit 

this practice if documentation in the 

driller’s report shows: 

(1) No indication of formation fluid 

influx before starting to pull the drill 

pipe from the hole; 

(2) The weight of returning drilling 

fluid is within 0.2 pounds per gallon (1.5 

pounds per cubic foot) of the drilling 

fluid entering the hole; and 

(3) Other drilling fluid properties are 

within the limits established by the 

program approved in the APD. 


Lhorne on DSK5TPTVN1PROD with CFR
107 

Safety & Environmental Enforcement, Interior § 250.457 

(b) Record each time you circulate 

drilling fluid in the hole in the driller’s 

report; 

(c) When coming out of the hole with 

drill pipe, you must fill the annulus 

with drilling fluid before the hydrostatic pressure decreases by 75 psi, or 

every five stands of drill pipe, whichever gives a lower decrease in hydrostatic pressure. You must calculate the 

number of stands of drill pipe and drill 

collars that you may pull before you 

must fill the hole. You must also calculate the equivalent drilling fluid volume needed to fill the hole. Both sets 

of numbers must be posted near the 

driller’s station. You must use a mechanical, volumetric, or electronic device to measure the drilling fluid required to fill the hole; 

(d) You must run and pull drill pipe 

and downhole tools at controlled rates 

so you do not swab or surge the well; 

(e) When there is an indication of 

swabbing or influx of formation fluids, 

you must take appropriate measures to 

control the well. You must circulate 

and condition the well, on or near-bottom, unless well or drilling-fluid conditions prevent running the drill pipe 

back to the bottom; 

(f) You must calculate and post near 

the driller’s console the maximum 

pressures that you may safely contain 

under a shut-in BOP for each casing 

string. The pressures posted must consider the surface pressure at which the 

formation at the shoe would break 

down, the rated working pressure of 

the BOP stack, and 70 percent of casing 

burst (or casing test as approved by the 

District Manager). As a minimum, you 

must post the following two pressures: 

(1) The surface pressure at which the 

shoe would break down. This calculation must consider the current drilling 

fluid weight in the hole; and 

(2) The lesser of the BOP’s rated 

working pressure or 70 percent of casing-burst pressure (or casing test otherwise approved by the District Manager); 

(g) You must install an operable 

drilling fluid-gas separator and 

degasser before you begin drilling operations. You must maintain this equipment throughout the drilling of the 

well; 

(h) Before pulling drill-stem test 

tools from the hole, you must circulate 

or reverse-circulate the test fluids in 

the hole. If circulating out test fluids 

is not feasible, you may bullhead test 

fluids out of the drill-stem test string 

and tools with an appropriate kill 

weight fluid; 

(i) When circulating, you must test 

the drilling fluid at least once each 

tour, or more frequently if conditions 

warrant. Your tests must conform to 

industry-accepted practices and include density, viscosity, and gel 

strength; hydrogenion concentration; 

filtration; and any other tests the District Manager requires for monitoring 

and maintaining drilling fluid quality, 

prevention of downhole equipment 

problems and for kick detection. You 

must record the results of these tests 

in the drilling fluid report; 

(j) Before you displace kill-weight 

fluid from the wellbore and/or riser to 

an underbalanced state, you must obtain approval from the BSEE District 

Manager. To obtain approval, you must 

submit with your APD or APM your 

reasons for displacing the kill-weight 

fluid and provide detailed step-by-step 

written procedures describing how you 

will safely displace these fluids. The 

step-by-step displacement procedures 

must address the following: 

(1) Number and type of independent 

barriers, as described in §250.420(b)(3), 

that are in place for each flow path 

that requires such barriers, 

(2) Tests you will conduct to ensure 

integrity of independent barriers, 

(3) BOP procedures you will use while 

displacing kill-weight fluids, and 

(4) Procedures you will use to monitor the volumes and rates of fluids entering and leaving the wellbore; and 

(k) In areas where permafrost and/or 

hydrate zones are present or may be 

present, you must control drilling fluid 

temperatures to drill safely through 

those zones.

FR 50894, Aug. 22, 2012] 

§ 250.457 What equipment is required 

to monitor drilling fluids? 

Once you establish drilling fluid returns, you must install and maintain 

the following drilling fluid-system 


Lhorne on DSK5TPTVN1PROD with CFR
108 

§ 250.458 30 CFR Ch. II (7–1–15 Edition) 

monitoring equipment throughout subsequent drilling operations. This equipment must have the following indicators on the rig floor: 

(a) Pit level indicator to determine 

drilling fluid-pit volume gains and 

losses. This indicator must include 

both a visual and an audible warning 

device; 

(b) Volume measuring device to accurately determine drilling fluid volumes 

required to fill the hole on trips; 

(c) Return indicator devices that indicate the relationship between drilling fluid-return flow rate and pump 

discharge rate. This indicator must include both a visual and an audible 

warning device; and 

(d) Gas-detecting equipment to monitor the drilling fluid returns. The indicator may be located in the drilling 

fluid-logging compartment or on the 

rig floor. If the indicators are only in 

the logging compartment, you must 

continually man the equipment and 

have a means of immediate communication with the rig floor. If the indicators are on the rig floor only, you 

must install an audible alarm. 

§ 250.458 What quantities of drilling 

fluids are required? 

(a) You must use, maintain, and replenish quantities of drilling fluid and 

drilling fluid materials at the drill site 

as necessary to ensure well control. 

You must determine those quantities 

based on known or anticipated drilling 

conditions, rig storage capacity, 

weather conditions, and estimated 

time for delivery. 

(b) You must record the daily inventories of drilling fluid and drilling fluid 

materials, including weight materials 

and additives in the drilling fluid report. 

(c) If you do not have sufficient quantities of drilling fluid and drilling fluid 

material to maintain well control, you 

must suspend drilling operations. 

§ 250.459 What are the safety requirements for drilling fluid-handling 

areas? 

You must classify drilling fluid-handling areas according to API RP 500, 

Recommended Practice for Classification of Locations for Electrical Installations at Petroleum Facilities, Classified as Class I, Division 1 and Division 

2 (as incorporated by reference in 

§250.198); or API RP 505, Recommended 

Practice for Classification of Locations 

for Electrical Installations at Petroleum Facilities, Classified as Class 1, 

Zone 0, Zone 1, and Zone 2 (as incorporated by reference in §250.198). In 

areas where dangerous concentrations 

of combustible gas may accumulate, 

you must install and maintain a ventilation system and gas monitors. 

Drilling fluid-handling areas must have 

the following safety equipment: 

(a) A ventilation system capable of 

replacing the air once every 5 minutes 

or 1.0 cubic feet of air-volume flow per 

minute, per square foot of area, whichever is greater. In addition: 

(1) If natural means provide adequate 

ventilation, then a mechanical ventilation system is not necessary; 

(2) If a mechanical system does not 

run continuously, then it must activate when gas detectors indicate the 

presence of 1 percent or more of combustible gas by volume; and 

(3) If discharges from a mechanical 

ventilation system may be hazardous, 

then you must maintain the drilling 

fluid-handling area at a negative pressure. You must protect the negative 

pressure area by using at least one of 

the following: a pressure-sensitive 

alarm, open-door alarms on each access 

to the area, automatic door-closing devices, air locks, or other devices approved by the District Manager; 

(b) Gas detectors and alarms except 

in open areas where adequate ventilation is provided by natural means. You 

must test and recalibrate gas detectors 

quarterly. No more than 90 days may 

elapse between tests; 

(c) Explosion-proof or pressurized 

electrical equipment to prevent the ignition of explosive gases. Where you 

use air for pressuring equipment, you 

must locate the air intake outside of 

and as far as practicable from hazardous areas; and 

(d) Alarms that activate when the 

mechanical ventilation system fails.

Lhorne on DSK5TPTVN1PROD with CFR
118 

§ 250.490 30 CFR Ch. II (7–1–15 Edition) 

(1) Contain the well-fluid influx by 

shutting in the well and pumping the 

fluids back into the formation. 

(2) Control the kick by using appropriate well-control techniques to prevent formation fracturing in an open 

hole within the pressure limits of the 

well equipment (drill pipe, work string, 

casing, wellhead, BOP system, and related equipment). The disposal of H2S 

and other gases must be through pressurized or atmospheric mud-separator 

equipment depending on volume, pressure and concentration of H2S. The 

equipment must be designed to recover 

well-control fluids and burn the gases 

separated from the well-control fluid. 

The well-control fluid must be treated 

to neutralize H2S and restore and 

maintain the proper quality. 

(o) Well testing in a zone known to contain H2S. When testing a well in a zone 

with H2S present, you must do all of 

the following: 

(1) Before starting a well test, conduct safety meetings for all personnel 

who will be on the facility during the 

test. At the meetings, emphasize the 

use of protective-breathing equipment, 

first-aid procedures, and the Contingency Plan. Only competent personnel 

who are trained and are knowledgeable 

of the hazardous effects of H2S must be 

engaged in these tests. 

(2) Perform well testing with the 

minimum number of personnel in the 

immediate vicinity of the rig floor and 

with the appropriate test equipment to 

safely and adequately perform the test. 

During the test, you must continuously 

monitor H2S levels. 

(3) Not burn produced gases except 

through a flare which meets the requirements of paragraph (q)(6) of this 

section. Before flaring gas containing 

H2S, you must activate SO2 monitoring 

equipment in accordance with paragraph (j)(11) of this section. If you detect SO2 in excess of 2 ppm, you must 

implement the personnel protective 

measures in your H2S Contingency 

Plan, required by paragraph (f) of this 

section. You must also follow the requirements of §250.1164. You must pipe 

gases from stored test fluids into the 

flare outlet and burn them. 

(4) Use downhole test tools and wellhead equipment suitable for H2S service. 

(5) Use tubulars suitable for H2S service. You must not use drill pipe for well 

testing without the prior approval of 

the District Manager. Water cushions 

must be thoroughly inhibited in order 

to prevent H2S attack on metals. You 

must flush the test string fluid treated 

for this purpose after completion of the 

test. 

(6) Use surface test units and related 

equipment that is designed for H2S 

service. 

(p) Metallurgical properties of equipment. When operating in a zone with 

H2S present, you must use equipment 

that is constructed of materials with 

metallurgical properties that resist or 

prevent sulfide stress cracking (also 

known as hydrogen embrittlement, 

stress corrosion cracking, or H2S embrittlement), chloride-stress cracking, 

hydrogen-induced cracking, and other 

failure modes. You must do all of the 

following: 

(1) Use tubulars and other equipment, 

casing, tubing, drill pipe, couplings, 

flanges, and related equipment that is 

designed for H2S service. 

(2) Use BOP system components, 

wellhead, pressure-control equipment, 

and related equipment exposed to H2Sbearing fluids in conformance with 

NACE Standard MR0175–03 (as specified 

in §250.198). 

(3) Use temporary downhole well-security devices such as retrievable 

packers and bridge plugs that are designed for H2S service. 

(4) When producing in zones bearing 

H2S, use equipment constructed of materials capable of resisting or preventing sulfide stress cracking. 

(5) Keep the use of welding to a minimum during the installation or modification of a production facility. Welding must be done in a manner that ensures resistance to sulfide stress cracking. 

(q) General requirements when operating in an H2S zone: (1) Coring operations. When you conduct coring operations in H2S-bearing zones, all personnel in the working area must wear 

protective-breathing equipment at 

least 10 stands in advance of retrieving 

the core barrel. Cores to be transported 

must be sealed and marked for the 

presence of H2S. 


Lhorne on DSK5TPTVN1PROD with CFR
119 

Safety & Environmental Enforcement, Interior § 250.500 

(2) Logging operations. You must treat 

and condition well-control fluid in use 

for logging operations to minimize the 

effects of H2S on the logging equipment. 

(3) Stripping operations. Personnel 

must monitor displaced well-control 

fluid returns and wear protectivebreathing equipment in the working 

area when the atmospheric concentration of H2S reaches 20 ppm or if the 

well is under pressure. 

(4) Gas-cut well-control fluid or well 

kick from H2S-bearing zone. If you decide 

to circulate out a kick, personnel in 

the working area during bottoms-up 

and extended-kill operations must wear 

protective-breathing equipment. 

(5) Drill- and workover-string design 

and precautions. Drill- and workoverstrings must be designed consistent 

with the anticipated depth, conditions 

of the hole, and reservoir environment 

to be encountered. You must minimize 

exposure of the drill- or workoverstring to high stresses as much as practical and consistent with well conditions. Proper handling techniques must 

be taken to minimize notching and 

stress concentrations. Precautions 

must be taken to minimize stresses 

caused by doglegs, improper stiffness 

ratios, improper torque, whip, abrasive 

wear on tool joints, and joint imbalance. 

(6) Flare system. The flare outlet must 

be of a diameter that allows easy nonrestricted flow of gas. You must locate 

flare line outlets on the downside of 

the facility and as far from the facility 

as is feasible, taking into account the 

prevailing wind directions, the wake 

effects caused by the facility and adjacent structure(s), and the height of all 

such facilities and structures. You 

must equip the flare outlet with an 

automatic ignition system including a 

pilot-light gas source or an equivalent 

system. You must have alternate 

methods for igniting the flare. You 

must pipe to the flare system used for 

H2S all vents from production process 

equipment, tanks, relief valves, burst 

plates, and similar devices. 

(7) Corrosion mitigation. You must use 

effective means of monitoring and controlling corrosion caused by acid gases 

(H2S and CO2) in both the downhole and 

surface portions of a production system. You must take specific corrosion 

monitoring and mitigating measures in 

areas of unusually severe corrosion 

where accumulation of water and/or 

higher concentration of H2S exists. 

(8) Wireline lubricators. Lubricators 

which may be exposed to fluids containing H2S must be of H2S-resistant 

materials. 

(9) Fuel and/or instrument gas. You 

must not use gas containing H2S for instrument gas. You must not use gas 

containing H2S for fuel gas without the 

prior approval of the District Manager. 

(10) Sensing lines and devices. Metals 

used for sensing line and safety-control 

devices which are necessarily exposed 

to H2S-bearing fluids must be constructed of H2S-corrosion resistant materials or coated so as to resist H2S 

corrosion. 

(11) Elastomer seals. You must use 

H2S-resistant materials for all seals 

which may be exposed to fluids containing H2S. 

(12) Water disposal. If you dispose of 

produced water by means other than 

subsurface injection, you must submit 

to the District Manager an analysis of 

the anticipated H2S content of the 

water at the final treatment vessel and 

at the discharge point. The District 

Manager may require that the water be 

treated for removal of H2S. The District Manager may require the submittal of an updated analysis if the 

water disposal rate or the potential 

H2S content increases. 

(13) Deck drains. You must equip open 

deck drains with traps or similar devices to prevent the escape of H2S gas 

into the atmosphere. 

(14) Sealed voids. You must take precautions to eliminate sealed spaces in 

piping designs (e.g., slip-on flanges, reinforcing pads) which can be invaded 

by atomic hydrogen when H2S is 

present.

§ 250.517 Blowout preventer system 

tests, inspections, and maintenance. 

(a) BOP pressure testing timeframes. 

You must pressure test your BOP system: 

(1) When installed; and 

(2) Before 14 days have elapsed since 

your last BOP pressure test. You must 

begin to test your BOP system before 

12 a.m. (midnight) on the 14th day following the conclusion of the previous 

test. However, the District Manager 

may require testing every 7 days if conditions or BOP performance warrant. 

(b) BOP test pressures. When you test 

the BOP system, you must conduct a 

low pressure and a high pressure test 

for each BOP component. Each individual pressure test must hold pressure 

long enough to demonstrate that the 

tested component(s) holds the required 

pressure. The District Manager may 

approve or require other test pressures 

or practices. Required test pressures 

are as follows: 

(1) All low pressure tests must be between 200 and 300 psi. Any initial pressure above 300 psi must be bled back to 

a pressure between 200 and 300 psi before starting the test. If the initial 

pressure exceeds 500 psi, you must 

bleed back to zero and reinitiate the 

test. You must conduct the low pressure test before the high pressure test. 

(2) For ram-type BOP’s, choke manifold, and other BOP equipment, the 

high pressure test must equal the rated 

working pressure of the equipment. 

(3) For annular-type BOP’s, the high 

pressure test must equal 70 percent of 

the rated working pressure of the 

equipment. 

(c) Duration of pressure test. Each test 

must hold the required pressure for 5 

minutes. 

(1) For surface BOP systems and surface equipment of a subsea BOP system, a 3-minute test duration is acceptable if you record your test pressures on the outermost half of a 4-hour 

chart, on a 1-hour chart, or on a digital 

recorder. 

(2) If the equipment does not hold the 

required pressure during a test, you 

must remedy the problem and retest 

the affected component(s). 

(d) Additional BOP testing requirements. You must: 

(1) Use water to test the surface BOP 

system; 

(2) Stump test a subsea BOP system

use drilling or completion fluids to 

conduct subsequent tests of a subsea 

BOP system. You must perform the initial subsea BOP test on the seafloor 

within 30 days of the stump test. 

(3) Alternate tests between control 

stations and pods. If a control station 

or pod is not functional, you must suspend further completion operations 

until that station or pod is operable; 

(4) Pressure test the blind or blindshear ram at least every 30 days; 

(5) Function test annulars and rams 

every 7 days; 

(6) Pressure-test variable bore-pipe 

rams against all sizes of pipe in use, excluding drill collars and bottom-hole 

tools; 

(7) Test affected BOP components following the disconnection or repair of 

any well-pressure containment seal in 

the wellhead or BOP stack assembly; 

(8) Test all ROV intervention functions on your subsea BOP stack during 

the stump test. Each ROV must be 

fully compatible with the BOP stack 

ROV intervention panels. You must 

also test and verify closure of at least 

one set of rams during the initial test 

on the seafloor through an ROV hot 

stab. You must submit test procedures, 

including how you will test each ROV 

function, with your APM for BSEE District Manager approval. You must: 

(i) Ensure that the ROV hot stabs are 

function tested and are capable of actuating, at a minimum, one set of pipe 

rams, one set of blind-shear rams, and 

unlatching the LMRP; 

(ii) Notify the appropriate BSEE District Manager a minimum of 72 hours 

prior to the stump test and initial test 

on the seafloor;

§ 250.522 How do I manage the thermal 

effects caused by initial production 

on a newly completed or recompleted well? 

A newly completed or recompleted 

well often has thermal casing pressure 

during initial startup. Bleeding casing 

pressure during the startup process is 

considered a normal and necessary operation to manage thermal casing pressure; therefore, you do not need to 

evaluate these operations as a casing

§ 250.617 Blowout preventer system 

testing, records, and drills. 

(a) BOP pressure tests. When you pressure test the BOP system you must 

conduct a low-pressure test and a highpressure test for each component. You 

must conduct the low-pressure test before the high-pressure test. For purposes of this section, BOP system components include ram-type BOP’s, related control equipment, choke and 

kill lines, and valves, manifolds, strippers, and safety valves. Surface BOP 

systems must be pressure tested with 

water. 

(1) Low pressure tests. All BOP system 

components must be successfully tested to a low pressure between 200 and 300 

psi. Any initial pressure equal to or 

greater than 300 psi must be bled back 

to a pressure between 200 and 300 psi 

before starting the test. If the initial 

pressure exceeds 500 psi, you must 

bleed back to zero before starting the 

test. 

(2) High pressure tests. All BOP system 

components must be successfully tested to the rated working pressure of the 

BOP equipment, or as otherwise approved by the District Manager. The 

annular-type BOP must be successfully 

tested at 70 percent of its rated working pressure or as otherwise approved 

by the District Manager. 

(3) Other testing requirements. Variable 

bore pipe rams must be pressure tested 

against the largest and smallest sizes 

of tubulars in use (jointed pipe, seamless pipe) in the well. 

(b) Times. The BOP systems shall be 

tested at the following times: 

(1) When installed; 

(2) At least every 7 days, alternating 

between control stations and at staggered intervals to allow each crew to 

operate the equipment. If either control system is not functional, further 

operations shall be suspended until the 

nonfunctional, system is operable. The 

test every 7 days is not required for 

blind or blind-shear rams. The blind or 

blind-shear rams shall be tested at 

least once every 30 days during operation. A longer period between blowout 

preventer tests is allowed when there is 

a stuck pipe or pressure-control operation and remedial efforts are being 

performed. The tests shall be conducted as soon as possible and before 

normal operations resume. The reason 

for postponing testing shall be entered 

into the operations log.

high pressure test to the rated working 

pressure of the connector or the expected surface pressure, whichever is 

less. You must successfully pressure 

test the dual check valves to the rated 

working pressure of the connector, the 

rated working pressure of the dual 

check valve, expected surface pressure, 

or the collapse pressure of the coiled 

tubing, whichever is less. 

(f) Recordings. You must record test 

pressures during BOP and coiled tubing 

tests on a pressure chart, or with a digital recorder, unless otherwise approved by the District Manager. The 

test interval for each BOP system component must be 5 minutes, except for 

coiled tubing operations, which must 

include a 10 minute high-pressure test 

for the coiled tubing string. Your representative at the facility must certify 

that the charts are correct. 

(g) Operations log. The time, date, and 

results of all pressure tests, actuations, 

inspections, and crew drills of the BOP 

system, system components, and marine risers shall be recorded in the operations log. The BOP tests shall be 

documented in accordance with the following: 

(1) The documentation shall indicate 

the sequential order of BOP and auxiliary equipment testing and the pressure and duration of each test. As an 

alternate, the documentation in the 

operations log may reference a BOP 

test plan that contains the required information and is retained on file at the 

facility. 

(2) The control station used during 

the test shall be identified in the operations log. For a subsea system, the 

pod used during the test shall be identified in the operations log. 

(3) Any problems or irregularities observed during BOP and auxiliary equipment testing and any actions taken to 

remedy such problems or irregularities 

shall be noted in the operations log.

have maintenance inspection, rating, 

repair, and alteration performed in accordance with the applicable provisions 

of API Pressure Vessel Inspections 

Code: In-Service Inspection, Rating, 

Repair, and Alteration, API 510 (except 

Sections 5.8 and 9.5) (as incorporated 

by reference in §250.198). 

(i) Pressure relief valves shall be designed, installed, and maintained in accordance with applicable provisions of 

sections I, IV, and VIII of the ASME 

Boiler and Pressure Vessel Code. The 

relief valves shall conform to the 

valve-sizing and pressure-relieving requirements specified in these documents; however, the relief valves, except completely redundant relief 

valves, shall be set no higher than the 

maximum-allowable working pressure 

of the vessel. All relief valves and vents 

shall be piped in such a way as to prevent fluid from striking personnel or 

ignition sources. 

(ii) Steam generators operating at 

less than 15 pounds per square inch 

gauge (psig) shall be equipped with a 

level safety low (LSL) sensor which 

will shut off the fuel supply when the 

water level drops below the minimum 

safe level. Steam generators operating 

at greater than 15 psig require, in addition to an LSL, a water-feeding device 

which will automatically control the 

water level. 

(iii) The lessee shall use pressure recorders to establish the new operating 

pressure ranges of pressure vessels at 

any time when there is a change in operating pressures that requires new 

settings for the high-pressure shut-in 

sensor and/or the low-pressure shut-in 

sensor as provided herein. The pressure-recorder charts used to determine 

current operating pressure ranges shall 

be maintained at the lessee’s field office nearest the OCS facility or at 

other locations conveniently available 

to the District Manager. The high-pressure shut-in sensor shall be set no 

higher than 15 percent or 5 psi, whichever is greater, above the highest operating pressure of the vessel. This setting shall also be set sufficiently below 

(5 percent or 5 psi, whichever is greater) the relief valve’s set pressure to assure that the pressure source is shut in 

before the relief valve activates. The 

low-pressure shut-in sensor shall activate no lower than 15 percent or 5 psi, 

whichever is greater, below the lowest 

pressure in the operating range. The 

activation of low-pressure sensors on 

pressure vessels which operate at less

use pressure recorders to establish the 

new operating pressure ranges of 

flowlines at any time when there is a 

significant change in operating pressures. The most recent pressure-recorder charts used to determine operating pressure ranges shall be maintained at the lessee’s field office nearest the OCS facility or at other locations conveniently available to the District Manager. The high-pressure shutin sensor(s) shall be set no higher than 

15 percent or 5 psi, whichever is greater, above the highest operating pressure of the line. But in all cases, it 

shall be set sufficiently below the maximum shut-in wellhead pressure or the 

gas-lift supply pressure to assure actuation of the SSV. The low-pressure 

shut-in sensor(s) shall be set no lower 

than 15 percent or 5 psi, whichever is 

greater, below the lowest operating 

pressure of the line in which it is installed. 

(ii) If a well flows directly to the 

pipeline before separation, the flowline 

and valves from the well located upstream of and including the header 

inlet valve(s) shall have a working 

pressure equal to or greater than the 

maximum shut-in pressure of the well 

unless the flowline is protected by one 

of the following: 

(A) A relief valve which vents into 

the platform flare scrubber or some 

other location approved by the District 

Manager. The platform flare scrubber 

shall be designed to handle, without 

liquid-hydrocarbon carryover to the 

flare, the maximum-anticipated flow of 

liquid hydrocarbons which may be relieved to the vessel. 

(B) Two SSV’s with independent

(c) Subsurface surveys. Depending 

upon the design and location of your 

proposed platform and the results of 


Lhorne on DSK5TPTVN1PROD with CFR
154 

§ 250.907 30 CFR Ch. II (7–1–15 Edition) 

the shallow hazard and geologic surveys, the Regional Supervisor may require you to perform a subsurface survey. This survey will include a testing 

program for investigating the stratigraphic and engineering properties of 

the soil that may affect the foundations or anchoring systems for your facility. The testing program must include adequate in situ testing, boring, 

and sampling to examine all important 

soil and rock strata to determine its 

strength classification, deformation 

properties, and dynamic characteristics. If required to perform a subsurface survey, you must prepare and 

submit to the Regional Supervisor a 

summary report to briefly describe the 

results of your soil testing program, 

the various field and laboratory test 

methods employed, and the applicability of these methods as they pertain 

to the quality of the samples, the type 

of soil, and the anticipated design application. You must explain how the 

engineering properties of each soil 

stratum affect the design of your platform. In your explanation you must describe the uncertainties inherent in 

your overall testing program, and the 

reliability and applicability of each 

test method. 

(d) Overall site investigation report. 

You must prepare and submit to the 

Regional Supervisor an overall site investigation report for your platform 

that integrates the findings of your 

shallow hazards surveys and geologic 

surveys, and, if required, your subsurface surveys. Your overall site investigation report must include analyses of the potential for: 

(1) Scouring of the seafloor; 

(2) Hydraulic instability; 

(3) The occurrence of sand waves; 

(4) Instability of slopes at the platform location; 

(5) Liquefaction, or possible reduction of soil strength due to increased 

pore pressures; 

(6) Degradation of subsea permafrost 

layers;

(8) Lateral loading; 

(9) Dynamic loading; 

(10) Settlements and displacements; 

(11) Plastic deformation and formation collapse mechanisms; and 

(12) Soil reactions on the platform 

foundations or anchoring systems. 

§ 250.907 Where must I locate foundation boreholes? 

(a) For fixed or bottom-founded platforms and tension leg platforms, your 

maximum distance from any foundation pile to a soil boring must not exceed 500 feet. 

(b) For deepwater floating platforms 

which utilize catenary or taut-leg 

moorings, you must take borings at 

the most heavily loaded anchor location, at the anchor points approximately 120 and 240 degrees around the 

anchor pattern from that boring, and, 

as necessary, other points throughout 

the anchor pattern to establish the soil 

profile suitable for foundation design 

purposes. 

§ 250.908 What are the minimum structural fatigue design requirements? 

(a) API RP 2A–WSD, Recommended 

Practice for Planning, Designing and 

Constructing Fixed Offshore Platforms 

(as incorporated by reference in 

§250.198), requires that the design fatigue life of each joint and member be 

twice the intended service life of the 

structure. When designing your platform, the following table provides minimum fatigue life safety factors for 

critical structural members and joints. 

If . . . Then . . . 

(1) There is sufficient structural redundancy to prevent catastrophic failure of the platform or structure under consideration, 

The results of the analysis must indicate a maximum calculated life of twice the design life of the platform. 

(2) There is not sufficient structural redundancy to prevent catastrophic failure of the platform or structure, The results of a fatigue analysis must indicate a minimum calculated life or three times the design life of the platform. 

(3) The desirable degree of redundancy is significantly reduced 

as a result of fatigue damage, 

The results of a fatigue analysis must indicate a minimum calculated life of three times the design life of the platform. 

(b) The documents incorporated by 

reference in §250.901 may require larger 

safety factors than indicated in paragraph (a) of this section for some key 


Lhorne on DSK5TPTVN1PROD with CFR
155 

Safety & Environmental Enforcement, Interior § 250.910 

components. When the documents incorporated by reference require a larger safety factor than the chart in paragraph (a) of this section, the requirements of the incorporated document 

will prevail. 

PLATFORM VERIFICATION PROGRAM

§ 250.909 What is the Platform 

Verification Program? 

The Platform Verification Program 

is the BSEE approval process for ensuring that floating platforms; platforms 

of a new or unique design; platforms in 

seismic areas; or platforms located in 

deepwater or frontier areas meet stringent requirements for design and construction. The program is applied during construction of new platforms and 

major modifications of, or repairs to, 

existing platforms. These requirements 

are in addition to the requirements of 

the Platform Approval Program described in §§250.904 through 250.908 of 

this subpart. 

§ 250.910 Which of my facilities are 

subject to the Platform Verification 

Program? 

(a) All new fixed or bottom-founded 

platforms that meet any of the following five conditions are subject to 

the Platform Verification Program: 

(1) Platforms installed in water 

depths exceeding 400 feet (122 meters); 

(2) Platforms having natural periods 

in excess of 3 seconds; 

(3) Platforms installed in areas of unstable bottom conditions; 

(4) Platforms having configurations 

and designs which have not previously 

been used or proven for use in the area; 

or 

(5) Platforms installed in seismically 

active areas. 

(b) All new floating platforms are 

subject to the Platform Verification 

Program to the extent indicated in the 

following table: 

If . . . Then . . . 

(1) Your new floating platform is a buoyant offshore facility that 

does not have a ship-shaped hull, 

The entire platform is subject to the Platform Verification Program including the following associated structures: 

(i) Drilling, production, and pipeline risers, and riser tensioning 

systems (each platform must be designed to accommodate 

all the loads imposed by all risers and riser does not have 

tensioning systems); 

(ii) Turrets and turret-and-hull interfaces; 

(iii) Foundations, foundation pilings and templates, and anchoring systems; and 

(iv) Mooring or tethering systems. 

(2) Your new floating platform is a buoyant offshore facility with 

a ship-shaped hull, 

Only the following structures that may be associated with a 

floating platform are subject to the Platform Verification Program: 

(i) Drilling, production, and pipeline risers, and riser tensioning 

systems (each platform must be designed to accommodate 

all the loads imposed by all risers and riser tensioning systems); 

(ii) Turrets and turret-and-hull interfaces; 

(iii) Foundations, foundation pilings and templates, and anchoring systems; and 

(iv) Mooring or tethering systems. 

(c) If a platform is originally subject 

to the Platform Verification Program, 

then the conversion of that platform at 

that same site for a new purpose, or 

making a major modification of, or 

major repair to, that platform, is also 

subject to the Platform Verification 

Program. A major modification includes any modification that increases 

loading on a platform by 10 percent or 

more. A major repair is a corrective operation involving structural members

to a transporter-operated pipeline on 

the OCS before crossing into State 

waters and that are regulated under 49 

CFR parts 192 and 195. 

Lease term pipelines are those pipelines owned and operated by a lessee or 

operator and are wholly contained 

within the boundaries of a single lease, 

unitized leases, or contiguous (not cornering) leases of that lessee or operator. 

Out-of-service pipelines are those pipelines that have not been used to transport oil, natural gas, sulfur, or produced water for more than 30 consecutive days. 

Pipelines are the piping, risers, and 

appurtenances installed for the purpose 

of transporting oil, gas, sulphur, and 

produced water. (Piping confined to a 

production platform or structure is 

covered in Subpart H, Production Safety Systems, and is excluded from this 

subpart.) 

Production facilities means OCS facilities that receive hydrocarbon production either directly from wells or from 

other facilities that produce hydrocarbons from wells. They may include 

processing equipment for treating the 

production or separating it into its 

various liquid and gaseous components 

before transporting it to shore. 

Right-of-way pipelines are those pipelines which— 

(1) Are contained within the boundaries of a single lease or group of unitized leases but are not owned and operated by the lessee or operator of that 

lease or unit, 

(2) Are contained within the boundaries of contiguous (not cornering) 

leases which do not have a common lessee or operator, 

(3) Are contained within the boundaries of contiguous (not cornering) 

leases which have a common lessee or 

operator but are not owned and operated by that common lessee or operator, or 

(4) Cross any portion of an unleased 

block(s).

Spec 6A (as incorporated by reference 

in §250.198), API Spec 6D (as incorporated by reference in §250.198), or the 

equivalent. A valve may not be used 

under operating conditions that exceed 

the applicable pressure-temperature 

ratings contained in those standards. 

(2) Pipeline flanges and flange accessories shall meet the minimum design 

requirements of ANSI B16.5, API Spec 

6A, or the equivalent (as incorporated 

by reference in 30 CFR 250.198). Each 

flange assembly must be able to withstand the maximum pressure at which 

the pipeline is to be operated and to 

maintain its physical and chemical 

properties at any temperature to which 

it is anticipated that it might be subjected in service. 

(3) Pipeline fittings shall have pressure-temperature ratings based on 

stresses for pipe of the same or equivalent material. The actual bursting 

strength of the fitting shall at least be 

equal to the computed bursting 

strength of the pipe. 

(4) If you are installing pipelines constructed of unbonded flexible pipe, you 

must design them according to the

(d) If the maximum source pressure 

(MSP) exceeds the pipeline’s MAOP, 

you must install and maintain redundant safety devices meeting the requirements of section A9 of API RP 14C 

(as incorporated by reference in 

§250.198). Pressure safety valves (PSV) 

may be used only after a determination 

by the Regional Supervisor that the

(a)(1) Pipelines greater than 85⁄8

inches in diameter and installed in 

water depths of less than 200 feet shall 

be buried to a depth of at least 3 feet 

unless they are located in pipeline congested areas or seismically active areas 

as determined by the Regional Supervisor. Nevertheless, the Regional Supervisor may require burial of any 

pipeline if the Regional Supervisor determines that such burial will reduce 

the likelihood of environmental degradation or that the pipeline may constitute a hazard to trawling operations 

or other uses. A trawl test or diver survey may be required to determine 

whether or not pipeline burial is necessary or to determine whether a pipeline has been properly buried. 

(2) Pipeline valves, taps, tie-ins, 

capped lines, and repaired sections that 

could be obstructive shall be provided 

with at least 3 feet of cover unless the 

Regional Supervisor determines that 


Lhorne on DSK5TPTVN1PROD with CFR
165 

Safety & Environmental Enforcement, Interior § 250.1004 

such items present no hazard to trawling or other operations. A protective 

device may be used to cover an obstruction in lieu of burial if it is approved by the Regional Supervisor 

prior to installation. 

(3) Pipelines shall be installed with a 

minimum separation of 18 inches at 

pipeline crossings and from obstructions. 

(4) Pipeline risers installed after 

April 1, 1988, shall be protected from 

physical damage that could result from 

contact with floating vessels. Riser 

protection on pipelines installed on or 

before April 1, 1988, may be required 

when the Regional Supervisor determines that significant damage potential exists. 

(b)(1) Pipelines shall be pressure tested with water at a stabilized pressure 

of at least 1.25 times the MAOP for at 

least 8 hours when installed, relocated, 

uprated, or reactivated after being outof-service for more than 1 year. 

(2) Prior to returning a pipeline to 

service after a repair, the pipeline shall 

be pressure tested with water or processed natural gas at a minimum stabilized pressure of at least 1.25 times 

the MAOP for at least 2 hours. 

(3) Pipelines shall not be pressure 

tested at a pressure which produces a 

stress in the pipeline in excess of 95 

percent of the specified minimum-yield 

strength of the pipeline. A temperature 

recorder measuring test fluid temperature synchronized with a pressure recorder along with deadweight test 

readings shall be employed for all pressure testing. When a pipeline is pressure tested, no observable leakage shall 

be allowed. Pressure gauges and recorders shall be of sufficient accuracy to 

verify that leakage is not occurring. 

(4) The Regional Supervisor may require pressure testing of pipelines to 

verify the integrity of the system when 

the Regional Supervisor determines 

that there is a reasonable likelihood 

that the line has been damaged or 

weakened by external or internal conditions. 

(c) When a pipeline is repaired utilizing a clamp, the clamp shall be a full 

encirclement clamp able to withstand 

the anticipated pipeline pressure. 

§ 250.1004 Safety equipment requirements for DOI pipelines.

operating pressure range. However, 

high pilots shall not be set above the 

pipeline’s MAOP. 

(4) Crossing pipelines on production 

or manned nonproduction platforms 

which do not receive production from 

the platform shall be equipped with an 

SDV immediately upon boarding the 

platform. The SDV shall be operated by 

a PSHL on the departing pipelines and 

connected to the platform automaticand remote-emergency shut-in systems. 

(5) The Regional Supervisor may require that oil pipelines be equipped 

with a metering system to provide a 

continuous volumetric comparison between the input to the line at the 

structure(s) and the deliveries onshore.

within 1 year of the effective date of 

the relinquishment, forfeiture, or cancellation unless this requirement is 

waived in writing by the Regional Supervisor. All such improvements not 

removed within the time provided 

herein shall become the property of the 

United States but that shall not relieve 

the holder of liability for the cost of 

their removal or for restoration of the 

site. Furthermore, the holder is responsible for accidents or damages which 

might occur as a result of failure to 

timely remove improvements and 

equipment and restore a site. An application for relinquishment of a right-ofway grant shall be filed in accordance 

with §250.1019 of this part.

you submit the pipeline right-of-way 

application. You must make all subsequent payments before the respective 

time periods begin. 

(e) Late payments. An interest charge 

will be assessed on unpaid and underpaid amounts from the date the 

amounts are due, in accordance with 

the provisions found in 30 CFR 1218.54. 

If you fail to make a payment that is 

late after written notice from ONRR, 

BSEE may initiate cancellation of the 

right-of-use grant and easement under 

§250.1013. 

§ 250.1013 Grounds for forfeiture of 

pipeline right-of-way grants. 

Failure to comply with the Act, regulations, or any conditions of the rightof-way grant prescribed by the Regional Supervisor shall be grounds for 

forfeiture of the grant in an appropriate judicial proceeding instituted by 

the United States in any U.S. District 

Court having jurisdiction in accordance with the provisions of 43 U.S.C. 

1349. 

§ 250.1014 When pipeline right-of-way 

grants expire. 

Any right-of-way granted under the 

provisions of this subpart remains in 

effect as long as the associated pipeline 

is properly maintained and used for the 

purpose for which the grant was made, 

unless otherwise expressly stated in 

the grant. Temporary cessation or suspension of pipeline operations shall not 

cause the grant to expire. However, if 

the purpose of the grant ceases to exist 

or use of the associated pipeline is permanently discontinued for any reason, 

the grant shall be deemed to have expired. 

§ 250.1015 Applications for pipeline 

right-of-way grants. 

(a) You must submit an original and 

three copies of an application for a new 

or modified pipeline ROW grant to the 

Regional Supervisor. The application 

must address those items required by 

§250.1007(a) or (b) of this subpart, as applicable. It must also state the primary 

purpose for which you will use the 

ROW grant. If the ROW has been used 

before the application is made, the application must state the date such use 

began, by whom, and the date the applicant obtained control of the improvement. When you file your application, you must pay the rental required 

under §250.1012 of this subpart, as well 

as the service fees listed in §250.125 of

§ 250.1016 Granting pipeline rights-ofway. 

(a) In considering an application for a 

right-of-way, the Regional Supervisor 

shall consider the potential effect of 

the associated pipeline on the human, 

marine, and coastal environments, life 

(including aquatic life), property, and 

mineral resources in the entire area 

during construction and operational 

phases. The Regional Supervisor shall 

prepare an environmental analysis in 

accordance with applicable policies and 

guidelines. To aid in the evaluation 

and determinations, the Regional Supervisor may request and consider 

views and recommendations of appropriate Federal Agencies, hold public 

meetings after appropriate notice, and 

consult, as appropriate, with State 

agencies, organizations, industries, and 

individuals. Before granting a pipeline 

right-of-way, the Regional Supervisor 

shall give consideration to any recommendation by the intergovernmental planning program, or similar 

process, for the assessment and management of OCS oil and gas transportation. 

(b) Should the proposed route of a 

right-of-way adjoin and subsequently 

cross any State submerged lands, the 

applicant shall submit evidence to the 

Regional Supervisor that the State(s) 

so affected has reviewed the application. The applicant shall also submit 

any comment received as a result of 

that review. In the event of a State 

recommendation to relocate the proposed route, the Regional Supervisor 

may consult with the appropriate 

State officials. 

(c)(1) The applicant shall submit photocopies of return receipts to the Regional Supervisor that indicate the 

date that each lessee or right-of-way 

holder referenced in §250.1015(c) of this 

part has received a copy of the application. Letters of no objection may be 

submitted in lieu of the return receipts. 

(2) The Regional Supervisor shall not 

take final action on a right-of-way application until the Regional Supervisor 

is satisfied that each such lessee or 

right-of-way holder has been afforded 

at least 30 days from the date determined in paragraph (c)(1) of this section in which to submit comments.

§ 250.1017 30 CFR Ch. II (7–1–15 Edition) 

(d) If a proposed right-of-way crosses 

any lands not subject to disposition by 

mineral leasing or restricted from oil 

and gas activities, it shall be rejected 

by the Regional Supervisor unless the 

Federal Agency with jurisdiction over 

such excluded or restricted area gives 

its consent to the granting of the 

right-of-way. In such case, the applicant, upon a request filed within 30 

days after receipt of the notification of 

such rejection, shall be allowed an opportunity to eliminate the conflict. 

(e)(1) If the application and other required information are found to be in 

compliance with applicable laws and 

regulations, the right-of-way may be 

granted. The Regional Supervisor may 

prescribe, as conditions to the right-ofway grant, stipulations necessary to 

protect human, marine, and coastal environments, life (including aquatic 

life), property, and mineral resources 

located on or adjacent to the right-ofway. 

(2) If the Regional Supervisor determines that a change in the application 

should be made, the Regional Supervisor shall notify the applicant that an 

amended application shall be filed subject to stipulated changes. The Regional Supervisor shall determine 

whether the applicant shall deliver 

copies of the amended application to 

other parties for comment. 

(3) A decision to reject an application 

shall be in writing and shall state the 

reasons for the rejection. 

§ 250.1017 Requirements for construction under pipeline right-of-way 

grants. 

(a) Failure to construct the associated right-of-way pipeline within 5 

years of the date of the granting of a 

right-of-way shall cause the grant to 

expire. 

(b)(1) A right-of-way holder shall ensure that the right-of-way pipeline is 

constructed in a manner that minimizes deviations from the right-of-way 

as granted. 

(2) If, after constructing the right-ofway pipeline, it is determined that a 

deviation from the proposed right-ofway as granted has occurred, the rightof-way holder shall— 

(i) Notify the operators of all leases 

and holders of all right-of-way grants 

in which a deviation has occurred, and 

within 60 days of the date of the acceptance by the Regional Supervisor of 

the completion of pipeline construction 

report, provide the Regional Supervisor 

with evidence of such notification; and 

(ii) Relinquish any unused portion of 

the right-of-way. 

(3) Substantial deviation of a rightof-way pipeline as constructed from the 

proposed right-of-way as granted may 

be grounds for forfeiture of the rightof-way. 

(c) If the Regional Supervisor determines that a significant change in conditions has occurred subsequent to the 

granting of a right-of-way but prior to 

the commencement of construction of 

the associated pipeline, the Regional 

Supervisor may suspend or temporarily 

prohibit the commencement of construction until the right-of-way grant 

is modified to the extent necessary to 

address the changed conditions. 

§ 250.1018 Assignment of pipeline 

right-of-way grants. 

(a) Assignment may be made of a 

right-of-way grant, in whole or of any 

lineal segment thereof, subject to the 

approval of the Regional Supervisor. 

An application for approval of an assignment of a right-of-way or of a lineal segment thereof, shall be filed in 

triplicate with the Regional Supervisor. 

(b) Any application for approval for 

an assignment, in whole or in part, of 

any right, title, or interest in a rightof-way grant must be accompanied by 

the same showing of qualifications of 

the assignees as is required of an applicant for a ROW in §250.1015 of this subpart and must be supported by a statement that the assignee agrees to comply with and to be bound by the terms 

and conditions of the ROW grant. The 

assignee must satisfy the bonding requirements in 30 CFR 550.1011. No 

transfer will be recognized unless and 

until it is first approved, in writing, by 

the Regional Supervisor. The assignee 

must pay the service fee listed in 

§250.125 of this part for a pipeline ROW 

assignment request. 

(c) Notwithstanding the provisions of 

paragraph (b) of this section, the requirement to pay a filing fee under 


Lhorne on DSK5TPTVN1PROD with CFR

§§ 250.1153–250.1155 [Reserved] 

APPROVALS PRIOR TO PRODUCTION

§ 250.1156 What steps must I take to 

receive approval to produce within 

500 feet of a unit or lease line? 

(a) You must obtain approval from 

the Regional Supervisor before you 

start producing from a reservoir within 

a well that has any portion of the completed interval less than 500 feet from a 

unit or lease line. Submit to BSEE the 

service fee listed in §250.125, according 

to the instructions in §250.126, and the 

supporting information, as listed in the 

table in §250.1167, with your request. 

The Regional Supervisor will determine whether approval of your request 

will maximize ultimate recovery, avoid 

the waste of natural resources, or protect correlative rights. You do not need 

to obtain approval if the adjacent 

leases or units have the same unit, 

lease (record title and operating 

rights), and royalty interests as the 

lease or unit you plan to produce. You 

do not need to obtain approval if the 

adjacent block is unleased. 

(b) You must notify the operator(s) of 

adjacent property(ies) that are within 

500 feet of the completion, if the adjacent acreage is a leased block in the 

Federal OCS. You must provide the Regional Supervisor proof of the date of 

the notification. The operators of the 

adjacent properties have 30 days after 

receiving the notification to provide 

the Regional Supervisor letters of acceptance or objection. If an adjacent 

operator does not respond within 30 

days, the Regional Supervisor will presume there are no objections and proceed with a decision. The notification 

must include: 

(1) The well name; 

(2) The rectangular coordinates (x, y) 

of the location of the top and bottom of 

the completion or target completion 

referenced to the North American 

Datum 1983, and the subsea depths of 

the top and bottom of the completion 

or target completion; 

(3) The distance from the completion 

or target completion to the unit or 

lease line at its nearest point; and 

(4) A statement indicating whether 

or not it will be a high-capacity completion having a perforated or open 

hole interval greater than 150 feet 

measured depth. 

§ 250.1157 How do I receive approval 

to produce gas-cap gas from an oil 

reservoir with an associated gas 

cap? 

(a) You must request and receive approval from the Regional Supervisor: 

(1) Before producing gas-cap gas from 

each completion in an oil reservoir 

that is known to have an associated 

gas cap. 

(2) To continue production from a 

well if the oil reservoir is not initially 

known to have an associated gas cap, 

but the oil well begins to show characteristics of a gas well. 

(b) For either request, you must submit the service fee listed in §250.125, 

according to the instructions in 

§250.126, and the supporting information, as listed in the table in §250.1167, 

with your request. 

(c) The Regional Supervisor will determine whether your request maximizes ultimate recovery. 

§ 250.1158 How do I receive approval 

to downhole commingle hydrocarbons? 

(a) Before you perforate a well, you 

must request and receive approval from 

the Regional Supervisor to commingle 

hydrocarbons produced from multiple 

reservoirs within a common wellbore. 

The Regional Supervisor will determine whether your request maximizes 

ultimate recovery. You must include 

the service fee listed in §250.125, according to the instructions in §250.126, 

and the supporting information, as listed in the table in §250.1167, with your 

request. 

(b) If one or more of the reservoirs 

proposed for commingling is a competitive reservoir, you must notify the operators of all leases that contain the 

reservoir that you intend to downhole 

commingle the reservoirs. Your request 

for approval of downhole commingling 

must include proof of the date of this 

notification. The notified operators 

have 30 days after notification to provide the Regional Supervisor with letters of acceptance or objection. If the 

notified operators do not respond within the specified period, the Regional 

Supervisor will assume the operators

175 

Safety & Environmental Enforcement, Interior § 250.1160 

do not object and proceed with a decision. 

PRODUCTION RATES

§ 250.1159 May the Regional Supervisor limit my well or reservoir production rates? 

(a) The Regional Supervisor may set 

a Maximum Production Rate (MPR) for 

a producing well completion, or set a 

Maximum Efficient Rate (MER) for a 

reservoir, or both, if the Regional Supervisor determines that an excessive 

production rate could harm ultimate 

recovery. An MPR or MER will be 

based on well tests and any limitations 

imposed by well and surface equipment, sand production, reservoir sensitivity, gas-oil and water-oil ratios, location of perforated intervals, and prudent operating practices. 

(b) If the Regional Supervisor sets an 

MPR for a producing well completion 

and/or an MER for a reservoir, you may 

not exceed those rates except due to 

normal variations and fluctuations in 

production rates as set by the Regional 

Supervisor. 

FLARING, VENTING, AND BURNING

HYDROCARBONS

§ 250.1160 When may I flare or vent 

gas? 

(a) You must request and receive approval from the Regional Supervisor to 

flare or vent natural gas at your facility, except in the following situations: 

Condition Additional requirements 

(1) When the gas is lease use gas (produced natural gas 

which is used on or for the benefit of lease operations such 

as gas used to operate production facilities) or is used as an 

additive necessary to burn waste products, such as H2S.

The volume of gas flared or vented may not exceed the 

amount necessary for its intended purpose. Burning waste 

products may require approval under other regulations. 

(2) During the restart of a facility that was shut in because of 

weather conditions, such as a hurricane.

Flaring or venting may not exceed 48 cumulative hours without 

Regional Supervisor approval. 

(3) During the blow down of transportation pipelines downstream of the royalty meter.(i) You must report the location, time, flare/vent volume, and 

reason for flaring/venting to the Regional Supervisor in writing within 72 hours after the incident is over. 

(ii) Additional approval may be required under subparts H and 

J of this part. 

(4) During the unloading or cleaning of a well, drill-stem testing, production testing, other well-evaluation testing, or the 

necessary blow down to perform these procedures.

You may not exceed 48 cumulative hours of flaring or venting 

per unloading or cleaning or testing operation on a single 

completion without Regional Supervisor approval. 

(5) When properly working equipment yields flash gas (natural 

gas released from liquid hydrocarbons as a result of a decrease in pressure, an increase in temperature, or both) from 

storage vessels or other low-pressure production vessels, 

and you cannot economically recover this flash gas.

You may not flare or vent more than an average of 50 MCF 

per day during any calendar month without Regional Supervisor approval. 

(6) When the equipment works properly but there is a temporary upset condition, such as a hydrate or paraffin plug.(i) For oil-well gas and gas-well flash gas (natural gas released 

from condensate as a result of a decrease in pressure, an 

increase in temperature, or both), you may not exceed 48 

continuous hours of flaring or venting without Regional Supervisor approval. 

(ii) For primary gas-well gas (natural gas from a gas well completion that is at or near its wellhead pressure; this does not 

include flash gas), you may not exceed 2 continuous hours 

of flaring or venting without Regional Supervisor approval. 

(iii) You may not exceed 144 cumulative hours of flaring or 

venting during a calendar month without Regional Supervisor 

approval. 

(7) When equipment fails to work properly, during equipment 

maintenance and repair, or when you must relieve system 

pressures.

(i) For oil-well gas and gas-well flash gas, you may not exceed 

48 continuous hours of flaring or venting without Regional 

Supervisor approval. 

(ii) For primary gas-well gas, you may not exceed 2 continuous 

hours of flaring or venting without Regional Supervisor approval. 

(iii) You may not exceed 144 cumulative hours of flaring or 

venting during a calendar month without Regional Supervisor 

approval. 

(iv) The continuous and cumulative hours allowed under this 

paragraph may be counted separately from the hours under 

paragraph (a)(6) of this section. 


Lhorne on DSK5TPTVN1PROD with CFR
176 

§ 250.1161 30 CFR Ch. II (7–1–15 Edition) 

(b) Regardless of the requirements in 

paragraph (a) of this section, you must 

not flare or vent gas over the volume 

approved in your Development Operations Coordination Document (DOCD) 

or your Development and Production 

Plan (DPP) submitted to BOEM. 

(c) The Regional Supervisor may establish alternative approval procedures 

to cover situations when you cannot 

contact the BSEE office, such as during non-office hours. 

(d) The Regional Supervisor may 

specify a volume limit, or a shorter 

time limit than specified elsewhere in 

this part, in order to prevent air quality degradation or loss of reserves. 

(e) If you flare or vent gas without 

the required approval, or if the Regional Supervisor determines that you 

were negligent or could have avoided 

flaring or venting the gas, the hydrocarbons will be considered avoidably 

lost or wasted. You must pay royalties 

on the loss or waste, according to 30 

CFR part 1202. You must value any gas 

or liquid hydrocarbons avoidably lost 

or wasted under the provisions of 30 

CFR part 1206. 

(f) Fugitive emissions from valves, 

fittings, flanges, pressure relief valves 

or similar components do not require 

approval under this subpart unless specifically required by the Regional Supervisor. 

§ 250.1161 When may I flare or vent 

gas for extended periods of time? 

You must request and receive approval from the Regional Supervisor to 

flare or vent gas for an extended period 

of time. The Regional Supervisor will 

specify the approved period of time, 

which will not exceed 1 year. The Regional Supervisor may deny your request if it does not ensure the conservation of natural resources or is not 

consistent with National interests relating to development and production 

of minerals of the OCS. The Regional 

Supervisor may approve your request 

for one of the following reasons: 

(a) You initiated an action which, 

when completed, will eliminate flaring 

and venting; or 

(b) You submit to the Regional Supervisor an evaluation supported by engineering, geologic, and economic data 

indicating that the oil and gas produced from the well(s) will not economically support the facilities necessary to sell the gas or to use the gas 

on or for the benefit of the lease. 

§ 250.1162 When may I burn produced 

liquid hydrocarbons? 

(a) You must request and receive approval from the Regional Supervisor to 

burn any produced liquid hydrocarbons. The Regional Supervisor may 

allow you to burn liquid hydrocarbons 

if you demonstrate that transporting 

them to market or re-injecting them is 

not technically feasible or poses a significant risk of harm to offshore personnel or the environment. 

(b) If you burn liquid hydrocarbons 

without the required approval, or if the 

Regional Supervisor determines that 

you were negligent or could have 

avoided burning liquid hydrocarbons, 

the hydrocarbons will be considered 

avoidably lost or wasted. You must pay 

royalties on the loss or waste, according to 30 CFR part 1202. You must value 

any liquid hydrocarbons avoidably lost 

or wasted under the provisions of 30 

CFR part 1206. 

§ 250.1163 How must I measure gas 

flaring or venting volumes and liquid hydrocarbon burning volumes, 

and what records must I maintain? 

(a) If your facility processes more 

than an average of 2,000 bopd during 

May 2010, you must install flare/vent 

meters within 180 days after May 2010. 

If your facility processes more than an 

average of 2,000 bopd during a calendar 

month after May 2010, you must install 

flare/vent meters within 120 days after 

the end of the month in which the average amount of oil processed exceeds 

2,000 bopd. 

(1) You must notify the Regional Supervisor when your facility begins to 

process more than an average of 2,000 

bopd in a calendar month; 

(2) The flare/vent meters must measure all flared and vented gas within 5 

percent accuracy; 

(3) You must calibrate the meters 

regularly, in accordance with the manufacturer’s recommendation, or at 

least once every year, whichever is 

shorter; and 


Lhorne on DSK5TPTVN1PROD with CFR
177 

Safety & Environmental Enforcement, Interior § 250.1164 

(4) You must use and maintain the 

flare/vent meters for the life of the facility. 

(b) You must report all hydrocarbons 

produced from a well completion, including all gas flared, gas vented, and 

liquid hydrocarbons burned, to Office 

of Natural Resources Revenue on Form 

ONRR–4054 (Oil and Gas Operations Report), in accordance with 30 CFR 

1210.102. 

(1) You must report the amount of 

gas flared and the amount of gas vented separately. 

(2) You may classify and report gas 

used to operate equipment on the lease, 

such as gas used to power engines, instrument gas, and gas used to maintain 

pilot lights, as lease use gas. 

(3) If flare/vent meters are required 

at one or more of your facilities, you 

must report the amount of gas flared 

and vented at each of those facilities 

separately from those facilities that do 

not require meters and separately from 

other facilities with meters. 

(4) If flare/vent meters are not required at your facility: 

(i) You may report the gas flared and 

vented on a lease or unit basis. Gas 

flared and vented from multiple facilities on a single lease or unit may be reported together. 

(ii) If you choose to install meters, 

you may report the gas volume flared 

and vented according to the method 

specified in paragraph (b)(3) of this section. 

(c) You must prepare and maintain 

records detailing gas flaring, gas venting, and liquid hydrocarbon burning for 

each facility for 6 years. 

(1) You must maintain these records 

on the facility for at least the first 2 

years and have them available for inspection by BSEE representatives. 

(2) After 2 years, you must maintain 

the records, allow BSEE representatives to inspect the records upon request and provide copies to the Regional Supervisor upon request, but are 

not required to keep them on the facility. 

(3) The records must include, at a 

minimum: 

(i) Daily volumes of gas flared, gas 

vented, and liquid hydrocarbons 

burned; 

(ii) Number of hours of gas flaring,

(h) What are the requirements for establishing and applying operating meter factors for liquid hydrocarbons? (1) If you 

use a mechanical-displacement prover, 

you must record proof runs until five 

out of six consecutive runs produce a 

difference between individual runs of 

no greater than .05 percent. You must 

use the average of the five accepted 

runs to compute the meter factor. 

(2) If you use a master meter, you 

must record proof runs until three consecutive runs produce a total meter 

factor difference of no greater than 

0.0005. The flow rate through the meters during the proving must be within 

10 percent of the rate at which the line 

meter will operate. The final meter 

factor is determined by averaging the 

meter factors of the three runs; 

(3) If you use a tank prover, you must 

record proof runs until two consecutive 

runs produce a meter factor difference 

of no greater than .0005. The final 

meter factor is determined by averaging the meter factors of the two 

runs; and

factors forward starting with the date 

of the proving. 

(i) Under what circumstances does a liquid hydrocarbon royalty meter need to be 

taken out of service, and what must I do? 

(1) If the difference between the meter 

factor and the previous factor exceeds 

0.0025 it is a malfunction factor, and 

you must: 

(i) Remove the meter from service 

and inspect it for damage or wear; 

(ii) Adjust or repair the meter, and 

reprove it; 

(iii) Apply the average of the malfunction factor and the previous factor 

to the production measured through 

the meter between the date of the previous factor and the date of the malfunction factor; and 

(iv) Indicate that a meter malfunction occurred and show all appropriate 

remarks regarding subsequent repairs 

or adjustments on the proving report.

the contractual tolerances, adjust the 

meter to function properly or remove 

it from service and replace it. 

(2) Correct the volumes to the last 

acceptable calibration as follows: 

(i) If the duration of the error can be 

determined, calculate the volume adjustment for that period. 

(ii) If the duration of the error cannot be determined, apply the volume 

adjustment to one-half of the time 

elapsed since the last calibration or 21 

days, whichever is less. 

(e) What are the requirements when 

natural gas from a Federal lease on the 

OCS is transferred to a gas plant before 

royalty determination? If natural gas 

from a Federal lease on the OCS is 

transferred to a gas plant before royalty determination:

Subpart M—Unitization 

§ 250.1300 What is the purpose of this 

subpart? 

This subpart explains how Outer Continental Shelf (OCS) leases are unitized. If you are an OCS lessee, use the 

regulations in this subpart for both 

competitive reservoir and unitization 

situations. The purpose of joint development and unitization is to: 

(a) Conserve natural resources; 

(b) Prevent waste; and/or 

(c) Protect correlative rights, including Federal royalty interests. 

§ 250.1301 What are the requirements 

for unitization? 

(a) Voluntary unitization. You and 

other OCS lessees may ask the Regional Supervisor to approve a request 

for voluntary unitization. The Regional Supervisor may approve the request for voluntary unitization if unitized operations: 

(1) Promote and expedite exploration 

and development; or 

(2) Prevent waste, conserve natural 

resources, or protect correlative rights, 

including Federal royalty interests, of 

a reasonably delineated and productive 

reservoir. 

(b) Compulsory unitization. The Regional Supervisor may require you and 

other lessees to unitize operations of a 

reasonably delineated and productive 

reservoir if unitized operations are necessary to: 

(1) Prevent waste; 

(2) Conserve natural resources; or 


Lhorne on DSK5TPTVN1PROD with CFR
188 

§ 250.1302 30 CFR Ch. II (7–1–15 Edition) 

(3) Protect correlative rights, including Federal royalty interests. 

(c) Unit area. The area that a unit includes is the minimum number of 

leases that will allow the lessees to 

minimize the number of platforms, facility installations, and wells necessary for efficient exploration, development, and production of mineral deposits, oil and gas reservoirs, or potential hydrocarbon accumulations common to two or more leases. A unit may 

include whole leases or portions of 

leases. 

(d) Unit agreement. You, the other lessees, and the unit operator must enter 

into a unit agreement. The unit agreement must: allocate benefits to unitized leases, designate a unit operator, 

and specify the effective date of the 

unit agreement. The unit agreement 

must terminate when: the unit no 

longer produces unitized substances, 

and the unit operator no longer conducts drilling or well-workover operations (§250.180) under the unit agreement, unless the Regional Supervisor 

orders or approves a suspension of production under §250.170. 

(e) Unit operating agreement. The unit 

operator and the owners of working interests in the unitized leases must 

enter into a unit operating agreement. 

The unit operating agreement must describe how all the unit participants 

will apportion all costs and liabilities 

incurred maintaining or conducting operations. When a unit involves one or 

more net-profit-share leases, the unit 

operating agreement must describe 

how to attribute costs and credits to 

the net-profit-share lease(s), and this 

part of the agreement must be approved by the Regional Supervisor. 

Otherwise, you must provide a copy of 

the unit operating agreement to the 

Regional Supervisor, but the Regional 

Supervisor does not need to approve 

the unit operating agreement. 

(f) Extension of a lease covered by unit 

operations. If your unit agreement expires or terminates, or the unit area 

adjusts so that no part of your lease remains within the unit boundaries, your 

lease expires unless: 

(1) Its initial term has not expired; 

(2) You conduct drilling, production, 

or well-reworking operations on your 

lease consistent with applicable regulations; or 

(3) BSEE orders or approves a suspension of production or operations for 

your lease. 

(g) Unit operations. If your lease, or 

any part of your lease, is subject to a 

unit agreement, the entire lease continues for the term provided in the 

lease, and as long thereafter as any 

portion of your lease remains part of 

the unit area, and as long as operations 

continue the unit in effect. 

(1) If you drill, produce or perform 

well-workover operations on a lease 

within a unit, each lease, or part of a 

lease, in the unit will remain active in 

accordance with the unit agreement. 

Following a discovery, if your unit 

ceases drilling activities for a reasonable time period between the delineation of one or more reservoirs and the 

initiation of actual development drilling or production operations and that 

time period would extend beyond your 

lease’s primary term or any extension 

under §250.180, the unit operator must 

request and obtain BSEE approval of a 

suspension of production under §250.170 

in order to keep the unit from terminating. 

(2) When a lease in a unit agreement 

is beyond the primary term and the 

lease or unit is not producing, the lease 

will expire unless: 

(i) You conduct a continuous drilling 

or well reworking program designed to 

develop or restore the lease or unit production; or 

(ii) BSEE orders or approves a suspension of operations under §250.170. 

§ 250.1302 What if I have a competitive 

reservoir on a lease? 

(a) The Regional Supervisor may require you to conduct development and 

production operations in a competitive 

reservoir under either a joint Development and Production Plan, submitted 

to BOEM or a unitization agreement. A 

competitive reservoir has one or more 

producing or producible well completions on each of two or more leases, or 

portions of leases, with different lease 

operating interests. For purposes of 

this paragraph, a producible well completion is a well which is capable of 

production and which is shut in at the 


Lhorne on DSK5TPTVN1PROD with CFR
189 

Safety & Environmental Enforcement, Interior § 250.1304 

well head or at the surface but not necessarily connected to production facilities and from which the operator plans 

future production. 

(b) You may request that the Regional Supervisor make a preliminary 

determination whether a reservoir is 

competitive. When you receive the preliminary determination, you have 30 

days (or longer if the Regional Supervisor allows additional time) to concur 

or to submit an objection with supporting evidence if you do not concur. 

The Regional Supervisor will make a 

final determination and notify you and 

the other lessees. 

(c) If you conduct drilling or production operations in a reservoir determined competitive by the Regional Supervisor, you and the other affected 

lessees must submit for approval a 

joint plan of operations. You must submit the joint plan within 90 days after 

the Regional Supervisor makes a final 

determination that the reservoir is 

competitive. The joint plan must provide for the development and/or production of the reservoir. You may submit supplemental plans for the Regional Supervisor’s approval. 

(d) If you and the other affected lessees cannot reach an agreement on a 

joint Development and Production 

Plan, submitted to BOEM within the 

approved period of time, each lessee 

must submit a separate plan to the Regional Supervisor. The Regional Supervisor will hold a hearing to resolve differences in the separate plans. If the 

differences in the separate plans are 

not resolved at the hearing and the Regional Supervisor determines that 

unitization is necessary under 

§250.1301(b), BSEE will initiate unitization under §250.1304. 

§ 250.1303 How do I apply for voluntary unitization? 

(a) You must file a request for a voluntary unit with the Regional Supervisor. Your request must include: 

(1) A draft of the proposed unit agreement; 

(2) A proposed initial plan of operation; 

(3) Supporting geological, geophysical, and engineering data; and 

(4) Other information that may be 

necessary to show that the unitization 

proposal meets the criteria of §250.1300. 

(b) The unit agreement must comply 

with the requirements of this part. 

BSEE will maintain and provide a 

model unit agreement for you to follow. If BSEE revises the model, BSEE 

will publish the revised model in the 

FEDERAL REGISTER. If you vary your 

unit agreement from the model agreement, you must obtain the approval of 

the Regional Supervisor. 

(c) After the Regional Supervisor accepts your unitization proposal, you, 

the other lessees, and the unit operator 

must sign and file copies of the unit 

agreement, the unit operating agreement, and the initial plan of operation 

with the Regional Supervisor for approval. 

(d) You must pay the service fee listed in §250.125 of this part with your request for a voluntary unitization proposal or the expansion of a previously 

approved voluntary unit to include additional acreage. Additionally, you 

must pay the service fee listed in 

§250.125 with your request for unitization revision. 

§ 250.1304 How will BSEE require unitization? 

(a) If the Regional Supervisor determines that unitization of operations 

within a proposed unit area is necessary to prevent waste, conserve natural resources of the OCS, or protect 

correlative rights, including Federal 

royalty interests, the Regional Supervisor may require unitization. 

(b) If you ask BSEE to require unitization, you must file a request with 

the Regional Supervisor. You must include a proposed unit agreement as described in §§250.1301(d) and 250.1303(b); a 

proposed unit operating agreement; a 

proposed initial plan of operation; supporting geological, geophysical, and 

engineering data; and any other information that may be necessary to show 

that unitization meets the criteria of 

§250.1300. The proposed unit agreement 

must include a counterpart executed 

by each lessee seeking compulsory 

unitization. Lessees who seek compulsory unitization must simultaneously 

serve on the nonconsenting lessees copies of: 


Lhorne on DSK5TPTVN1PROD with CFR
190 

§ 250.1400 30 CFR Ch. II (7–1–15 Edition) 

(1) The request; 

(2) The proposed unit agreement with 

executed counterparts; 

(3) The proposed unit operating 

agreement; and 

(4) The proposed initial plan of operation. 

(c) If the Regional Supervisor initiates compulsory unitization, BSEE will 

serve all lessees of the proposed unit 

area with a proposed unitization plan 

and a statement of reasons for the proposed unitization. 

(d) The Regional Supervisor will not 

require unitization until BSEE provides all lessees of the proposed unit 

area written notice and an opportunity 

for a hearing. If you want BSEE to 

hold a hearing, you must request it 

within 30 days after you receive written notice from the Regional Supervisor or after you are served with a request for compulsory unitization from 

another lessee. 

(e) BSEE will not hold a hearing 

under this paragraph until at least 30 

days after BSEE provides written notice of the hearing date to all parties 

owning interests that would be made 

subject to the unit agreement. The Regional Supervisor must give all lessees 

of the proposed unit area an opportunity to submit views orally and in 

writing and to question both those 

seeking and those opposing compulsory 

unitization. Adjudicatory procedures 

are not required. The Regional Supervisor will make a decision based upon a 

record of the hearing, including any 

written information made a part of the 

record. The Regional Supervisor will 

arrange for a court reporter to make a 

verbatim transcript. The party seeking 

compulsory unitization must pay for 

the court reporter and pay for and provide to the Regional Supervisor within 

10 days after the hearing three copies 

of the verbatim transcript. 

(f) The Regional Supervisor will issue 

an order that requires or rejects compulsory unitization. That order must 

include a statement of reasons for the 

action taken and identify those parts 

of the record which form the basis of 

the decision. Any adversely affected 

party may appeal the final order of the 

Regional Supervisor under 30 CFR part 

290.

days to either pay the penalty or file 

an appeal in accordance with 30 CFR 

part 290, subpart A. 

(b) If you file an appeal, you must either: 

(1) Submit a surety bond in the 

amount of the penalty to the appropriate Leasing Office in the Region 

where the penalty was assessed, following instructions that the Reviewing 

Officer will include in the final decision; or 

(2) Notify the appropriate Leasing Office, in the Region where the penalty 

was assessed, that you want your leasespecific/area-wide bond on file to be 

used as the bond for the penalty 

amount. 

(c) If you choose the alternative in 

paragraph (b)(2) of this section, the 

BOEM Regional Director may require 


Lhorne on DSK5TPTVN1PROD with CFR
192 

§ 250.1450 30 CFR Ch. II (7–1–15 Edition) 

additional security (i.e., security in excess of your existing bond) to ensure 

sufficient coverage during an appeal. In 

that event, the Regional Director will 

require you to post the supplemental 

bond with the regional office in the 

same manner as under 30 CFR 556.53(d) 

through (f). If the Regional Director 

determines the appeal should be covered by a lease-specific abandonment 

account then you must establish an account that meets the requirements of 

30 CFR part 556.56. 

(d) If you do not either pay the penalty or file a timely appeal, BSEE will 

take one or more of the following actions: 

(1) We will collect the amount you 

were assessed, plus interest, late payment charges, and other fees as provided by law, from the date you received the Reviewing Officer’s final decision until the date we receive payment; 

(2) We may initiate additional enforcement, including, if appropriate, 

cancellation of the lease, right-of-way, 

license, permit, or approval, or the forfeiture of a bond under this part; or 

(3) We may bar you from doing further business with the Federal Government according to Executive Orders 

12549 and 12689, and section 2455 of the 

Federal Acquisition Streamlining Act 

of 1994, 31 U.S.C. 6101. The Department 

of the Interior’s regulations implementing these authorities are found at 

43 CFR part 12, subpart D.

GENERAL PROVISIONS

§ 250.1470 How does BSEE decide what

be? 

We determine the amount of the penalty by considering the severity of the 

violations, your history of compliance, 

and if you are a small business. 

§ 250.1471 Does the penalty affect 

whether I owe interest? 

If you do not pay the penalty by the

on the penalty amount at the same 

rate interest is assessed under 30 CFR 

1218.54.

issue a decision in accordance with the 

evidence presented and applicable law. 

§ 250.1473 How may I appeal the Administrative Law Judge’s decision?

and did not appeal the Administrative 

Law Judge’s determination to the 

IBLA under §250.1473; 

(3) You received an IBLA decision

case. 

(e) If you do not pay, that amount is 

subject to collection under the provisions of §250.1477. 

§ 250.1476 Can BSEE reduce my penalty once it is assessed?

your payment under 30 U.S.C. 1719(k).

assessment of a penalty, the court 

shall have jurisdiction to award the 

amount assessed plus interest assessed 

from the date of the expiration of the 

90-day period referred to in §250.1474. 

The amount of any penalty, as finally 

determined, may be deducted from any 

sum owing to you by the United States. 

CRIMINAL PENALTIES

§ 250.1480 May the United States 

criminally prosecute me for violations under Federal oil and gas 

leases? 

If you commit an act for which a 

civil penalty is provided at 30 U.S.C.

States may pursue criminal penalties 

as provided at 30 U.S.C. 1720, in addition to any authority for prosecution

Lhorne on DSK5TPTVN1PROD with CFR
196

BOEM instructions. BSEE will give 

you written information and standard 

forms for BOEM-specified surety instrument requirements. 

(b) BOEM will use a bank-rating service to determine whether a financial 

institution has an acceptable rating to 

provide a surety instrument adequate 

to indemnify the lessor from loss or 

damage. 

(1) Administrative appeal bonds must 

be issued by a qualified surety company which the Department of the 

Treasury has approved. 

(2) Irrevocable letters of credit or 

certificates of deposit must be from a

BOEM with a minimum 1-year period 

of coverage subject to automatic renewal up to 5 years. 

§ 250.1491 How will BOEM determine 

the amount of my bond or other 

surety instrument? 

(a) The BOEM bond-approving officer 

may approve your surety if he or she 

determines that the amount is adequate to guarantee payment. The 

amount of your surety may vary depending on the form of the surety and 

how long the surety is effective. 

(1) The amount of the BOEM-specified surety instrument must include 

the principal amount owed under the 

Notice of Noncompliance or Notice of 

Civil Penalty plus any accrued interest 

we determine is owed plus projected interest for a 1-year period. 

(2) Treasury book-entry bond or note 

amounts must be equal to at least 120 

percent of the required surety amount. 

(b) If your appeal is not decided within 1 year from the filing date, you must 

increase the surety amount to cover 

additional estimated interest for another 1-year period. You must continue 

to do this annually on the date your 

appeal was filed. We will determine the 

additional estimated interest and notify you of the amount so you can 

amend your surety instrument. 

(c) You may submit a single surety 

instrument that covers multiple appeals. You may change the instrument 

to add new amounts under appeal or remove amounts that have been adjudicated in your favor or that you have 

paid, if you: 

(1) Amend the single surety instrument annually on the date you filed 

your first appeal; and 

(2) Submit a separate surety instrument for new amounts under appeal 

until you amend the instrument to 

cover the new appeals.

notifies you that you must redemonstrate financial solvency. 

§ 250.1496 How will BOEM determine 

if I am financially solvent? 

(a) The BOEM bond-approving officer 

will determine your financial solvency 


Lhorne on DSK5TPTVN1PROD with CFR
197 

Safety & Environmental Enforcement, Interior § 250.1500 

by examining your total net worth, including, as appropriate, the net worth 

of your affiliated entities. 

(b) If your net worth, minus the 

amount we would require as surety 

under §§250.1490 and 250.1491 for all orders you have appealed is greater than 

$300 million, you are presumptively 

deemed financially solvent, and we will 

not require you to post a bond or other 

surety instrument. 

(c) If your net worth, minus the 

amount we would require as surety 

under §§250.1490 and 250.1491 for all orders you have appealed is less than $300 

million, you must submit the following 

to BSEE by one of the methods in 

§250.1495(a):

consult a business-information, or 

credit-reporting service or program to 

determine your financial solvency; and 

(2) A nonrefundable $50 processing 

fee: 

(i) You must pay the processing fee

payments; 

(ii) You must submit the fee with 

your request under paragraph (c)(1) of 

this section, and then annually on the 

date we first determined that you demonstrated financial solvency, as long as 

you are not able to demonstrate financial solvency under paragraph (a) of 

this section and you have active appeals. 

(d) If you request that we consult a 

business-information or credit-reporting service or program under paragraph 

(c) of this section: 

(1) We will use criteria similar to 

that which a potential creditor would 

use to lend an amount equal to the 

bond or other surety instrument we 

would require under §§250.1490 and 

250.1491; 

(2) For us to consider you financially 

solvent, the business-information or 

credit-reporting service or program 

must demonstrate your degree of risk 

as low to moderate: 

(i) If our bond-approving officer determines that the business-information 

or credit-reporting service or program 

information demonstrates your financial solvency to our satisfaction, our 

bond-approving officer will not require 

you to post a bond or other surety instrument under §§250.1490 and 250.1491; 

(ii) If our bond-approving officer determines that the business-information 

or credit-reporting service or program 

information does not demonstrate your 

financial solvency to our satisfaction, 

our bond-approving officer will require 

you to post a bond or other surety instrument under §§250.1490 and 250.1491 

or pay the obligation. 

§ 250.1497 When will BOEM monitor 

my financial solvency? 

(a) If you are presumptively financially solvent under §250.1496(b), BOEM 

will determine your net worth as described under §250.1496(b) and (c) to 

evaluate your financial solvency at 

least annually on the date we first determined that you demonstrated financial solvency as long as you have active appeals and each time you appeal 

a new order. 

(b) If you ask us to consult a business-information or credit-reporting 

service or program under §250.1496(c), 

we will consult a service or program 

annually as long as you have active appeals and each time you appeal a new 

order. 

(c) If our bond-approving officer determines that you are no longer financially solvent, you must post a bond or 

other BOEM-specified surety instrument under §§250.1490 and 250.1491.

§ 250.1605 30 CFR Ch. II (7–1–15 Edition) 

drilling operation. The information 

shall be submitted with, or prior to, 

the submission of Form BSEE–0123, Application for Permit to Drill (APD), in 

accordance with §250.1617 of this subpart. After a drilling unit has been approved by a BSEE district office, the 

information required in this paragraph 

need not be resubmitted unless required by the District Manager or 

there are changes in the equipment 

that affect the rated capacity of the 

unit. 

(c) Oceanographic, meteorological, and 

drilling unit performance data. Where 

oceanographic, meteorological, and 

drilling unit performance data are not 

otherwise readily available, lessees 

shall collect and report such data upon 

request to the District Manager. The 

type of information to be collected and 

reported will be determined by the District Manager in the interests of safety 

in the conduct of operations and the 

structural integrity of the drilling 

unit. 

(d) Foundation requirements. When the 

lessee fails to provide sufficient information pursuant to 30 CFR 550.211 

through 550.228 and 30 CFR 550.241 

through 550.262 to support a determination that the seafloor is capable of supporting a specific bottom-founded drilling unit under the site-specific soil and 

oceanographic conditions, the District 

Manager may require that additional 

surveys and soil borings be performed 

and the results submitted for review 

and evaluation by the District Manager 

before approval is granted for commencing drilling operations. 

(e) Tests, surveys, and samples. (1) Lessees shall drill and take cores and/or 

run well and mud logs through the objective interval to determine the presence, quality, and quantity of sulphur 

and other minerals (e.g., oil and gas) in 

the cap rock and the outline of the 

commercial sulphur deposit. 

(2) Inclinational surveys shall be obtained on all vertical wells at intervals 

not exceeding 1,000 feet during the normal course of drilling. Directional surveys giving both inclination and azimuth shall be obtained on all directionally drilled wells at intervals not 

exceeding 500 feet during the normal 

course of drilling and at intervals not 

exceeding 200 feet in all planned anglechange portions of the borehole. 

(3) Directional surveys giving both 

inclination and azimuth shall be obtained on both vertically and directionally drilled wells at intervals not 

exceeding 500 feet prior to or upon setting a string of casing, or production 

liner, and at total depth. Composite directional surveys shall be prepared 

with the interval shown from the bottom of the conductor casing. In calculating all surveys, a correction from 

the true north to Universal-Transverse-Mercator-Grid-north or LambertGrid-north shall be made after making 

the magnetic-to-true-north correction. 

A composite dipmeter directional survey or a composite measurement 

while-drilling directional survey will 

be acceptable as fulfilling the applicable requirements of this paragraph. 

(4) Wells are classified as vertical if 

the calculated average of inclination 

readings weighted by the respective interval lengths between readings from 

surface to drilled depth does not exceed 

3 degrees from the vertical. When the 

calculated average inclination readings 

weighted by the length of the respective interval between readings from the 

surface to drilled depth exceeds 3 degrees, the well is classified as directional. 

(5) At the request of a holder of an 

adjoining lease, the Regional Supervisor may, for the protection of correlative rights, furnish a copy of the directional survey to that leaseholder. 

(f) Fixed drilling platforms. Applications for installation of fixed drilling 

platforms or structures including artificial islands shall be submitted in accordance with the provisions of subpart 

I, Platforms and Structures, of this 

part. Mobile drilling units that have 

their jacking equipment removed or 

have been otherwise immobilized are 

classified as fixed bottom founded drilling platforms. 

(g) Crane operations. You must operate a crane installed on fixed platforms 

according to §250.108 of this subpart. 

(h) Diesel-engine air intakes. Diesel-engine air intakes must be equipped with 

a device to shut down the diesel engine 

in the event of runaway. Diesel engines 

that are continuously attended must 


Lhorne on DSK5TPTVN1PROD with CFR
203 

Safety & Environmental Enforcement, Interior § 250.1608 

be equipped with either remote-operated manual or automatic-shutdown 

devices. Diesel engines that are not 

continuously attended must be 

equipped with automatic shutdown devices. 

§ 250.1606 Control of wells. 

The lessee shall take necessary precautions to keep its wells under control at all times. Operations shall be 

conducted in a safe and workmanlike 

manner. The lessee shall utilize the 

best available and safest drilling technologies and state-of-the-art methods 

to evaluate and minimize the potential 

for a well to flow or kick. The lessee 

shall utilize personnel who are trained 

and competent and shall utilize and 

maintain equipment and materials necessary to assure the safety and protection of personnel, equipment, natural 

resources, and the environment. 

§ 250.1607 Field rules. 

When geological and engineering information in a field enables a District 

Manager to determine specific operating requirements, field rules may be 

established for drilling, well completion, or well workover on the District 

Manager’s initiative or in response to a 

request from a lessee; such rules may 

modify the specific requirements of 

this subpart. After field rules have 

been established, operations in the 

field shall be conducted in accordance 

with such rules and other requirements 

of this subpart. Field rules may be 

amended or canceled for cause at any 

time upon the initiative of the District 

Manager or upon the request of a lessee. 

§ 250.1608 Well casing and cementing. 

(a) General requirements. (1) For the 

purpose of this subpart, the several 

casing strings in order of normal installation are: 

(i) Drive or structural, 

(ii) Conductor, 

(iii) Cap rock casing, 

(iv) Bobtail cap rock casing (required 

when the cap rock casing does not penetrate into the cap rock), 

(v) Second cap rock casing (brine 

wells), and 

(vi) Production liner. 

(2) The lessee shall case and cement 

all wells with a sufficient number of 

strings of casing cemented in a manner 

necessary to prevent release of fluids 

from any stratum through the wellbore 

(directly or indirectly) into the sea, 

protect freshwater aquifers from contamination, support unconsolidated 

sediments, and otherwise provide a 

means of control of the formation pressures and fluids. Cement composition, 

placement techniques, and waiting 

time shall be designed and conducted 

so that the cement in place behind the 

bottom 500 feet of casing or total 

length of annular cement fill, if less, 

attains a minimum compressive 

strength of 160 pounds per square inch 

(psi). 

(3) The lessee shall install casing designed to withstand the anticipated 

stresses imposed by tensile, compressive, and buckling loads; burst and collapse pressures; thermal effects; and 

combinations thereof. Safety factors in 

the drilling and casing program designs 

shall be of sufficient magnitude to provide well control during drilling and to 

assure safe operations for the life of 

the well. 

(4) In cases where cement has filled 

the annular space back to the mud 

line, the cement may be washed out or 

displaced to a depth not exceeding the 

depth of the structural casing shoe to 

facilitate casing removal upon well 

abandonment if the District Manager 

determines that subsurface protection 

against damage to freshwater aquifers 

and against damage caused by adverse 

loads, pressures, and fluid flows is not 

jeopardized. 

(5) If there are indications of inadequate cementing (such as lost returns, 

cement channeling, or mechanical failure of equipment), the lessee shall 

evaluate the adequacy of the cementing operations by pressure testing the 

casing shoe. If the test indicates inadequate cementing, the lessee shall initiate remedial action as approved by 

the District Manager. For cap rock casing, the test for adequacy of cementing 

shall be the pressure testing of the annulus between the cap rock and the 

conductor casings. The pressure shall 


Lhorne on DSK5TPTVN1PROD with CFR
204 

§ 250.1609 30 CFR Ch. II (7–1–15 Edition) 

not exceed 70 percent of the burst pressure of the conductor casing or 70 percent of the collapse pressure of the cap 

rock casing. 

(b) Drive or structural casing. This casing shall be set by driving, jetting, or 

drilling to a minimum depth of 100 feet 

below the mud line or such other 

depth, as may be required or approved 

by the District Manager, in order to 

support unconsolidated deposits and to 

provide hole stability for initial drilling operations. If this portion of the 

hole is drilled, a quantity of cement 

sufficient to fill the annular space back 

to the mud line shall be used. 

(c) Conductor and cap rock casing setting and cementing requirements. (1) Conductor and cap rock casing design and 

setting depths shall be based upon relevant engineering and geologic factors 

including the presence or absence of 

hydrocarbons, potential hazards, and 

water depths. The proposed casing setting depths may be varied, subject to 

District Manager approval, to permit 

the casing to be set in a competent formation or through formations determined desirable to be isolated from the 

wellbore by casing for safer drilling operations. However, the conductor casing shall be set immediately prior to 

drilling into formations known to contain oil or gas or, if unknown, upon encountering such formations. Cap rock 

casing shall be set and cemented 

through formations known to contain 

oil or gas or, if unknown, upon encountering such formations. Upon encountering unexpected formation pressures, 

the lessee shall submit a revised casing 

program to the District Manager for 

approval. 

(2) Conductor casing shall be cemented with a quantity of cement that 

fills the calculated annular space back 

to the mud line. Cement fill shall be 

verified by the observation of cement 

returns. In the event that observation 

of cement returns is not feasible, additional quantities of cement shall be 

used to assure fill to the mud line. 

(3) Cap rock casing shall be cemented 

with a quantity of cement that fills the 

calculated annular space to at least 200 

feet inside the conductor casing. When 

geologic conditions such as near surface fractures and faulting exist, cap 

rock casing shall be cemented with a 

quantity of cement that fills the calculated annular space to the mud line, 

unless otherwise approved by the District Manager. In brine wells, the second cap rock casing shall be cemented 

with a quantity of cement that fills the 

calculated annular space to at least 200 

feet above the setting depth of the first 

cap rock casing. 

(d) Bobtail cap rock casing setting and 

cementing requirements. (1) Bobtail cap 

rock casing shall be set on or just in 

cap rock and lapped a minimum of 100 

feet into the previous casing string. 

(2) Sufficient cement shall be used to 

fill the annular space to the top of the 

bobtail cap rock casing. 

(e) Production liner setting and cementing requirements. (1) Production liners 

for sulphur wells and bleedwells shall 

be set in cap rock at or above the bottom of the open hole (hole that is open 

in cap rock, below the bottom of the 

cap rock casing) and lapped into the 

previous casing string or to the surface. For brine wells, the liner shall be 

set in salt and lapped into the previous 

casing string or to the surface. 

(2) The production liner is not required to be cemented unless the cap 

rock contains oil or gas. If the cap rock 

contains oil or gas, sufficient cement 

shall be used to fill the annular space 

to the top of the production liner. 

§ 250.1609 Pressure testing of casing. 

(a) Prior to drilling the plug after cementing, all casing strings, except the 

drive or structural casing, shall be 

pressure tested. The conductor casing 

shall be tested to at least 200 psi. All 

casing strings below the conductor casing shall be tested to 500 psi or 0.22 psi/ 

ft, whichever is greater. (When oil or 

gas is not present in the cap rock, the 

production liner need not be cemented 

in place; thus, it would not be subject 

to pressure testing.) If the pressure declines more than 10 percent in 30 minutes or if there is another indication of 

a leak, the casing shall be recemented, 

repaired, or an additional casing string 

run and the casing tested again. The 

above procedures shall be repeated 

until a satisfactory test is obtained. 

The time, conditions of testing, and results of all casing pressure tests shall 

be recorded in the driller’s report. 


Lhorne on DSK5TPTVN1PROD with CFR
205 

Safety & Environmental Enforcement, Interior § 250.1610 

(b) After cementing any string of casing other than structural, drilling shall 

not be resumed until there has been a 

timelapse of at least 8 hours under 

pressure for the conductor casing 

string or 12 hours under pressure for all 

other casing strings. Cement is considered under pressure if one or more float 

valves are shown to be holding the cement in place or when other means of 

holding pressure are used. 

§ 250.1610 Blowout preventer systems 

and system components. 

(a) General. The blowout preventer 

(BOP) systems and system components 

shall be designed, installed, used, 

maintained, and tested to assure well 

control. 

(b) BOP stacks. The BOP stacks shall 

consist of an annular preventer and the 

number of ram-type preventers as specified under paragraphs (e) and (f) of 

this section. The pipe rams shall be of 

proper size to fit the drill pipe in use.

may be of the automatic-reset type. 

(iii) A fuel-gas odorant or an automatic gas-detection and alarm system 

is required in enclosed, continuously 

manned areas of the facility that are 

provided with fuel gas. Living quarters 

and doghouses not containing a gas 

source and not located in a classified 

area do not require a gas detection system. 

(iv) The District Manager may require the installation and maintenance 

of a gas detector or alarm in any potentially hazardous area. 

(v) Fire- and gas-detection systems 

must be an approved type, designed and 

installed according to API RP 14C, API 

RP 14G, and either API RP 14F or API 

RP 14FZ (the preceding four documents 

as incorporated by reference in 

§250.198).

§ 250.1919 What criteria for investigation of incidents must be in my 

SEMS program? 

To learn from incidents and help prevent similar incidents, your SEMS program must establish procedures for investigation of all incidents with serious safety or environmental consequences and require investigation of 

incidents that are determined by facility management or BSEE to have possessed the potential for serious safety 

or environmental consequences. Incident investigations must be initiated 

as promptly as possible, with due regard for the necessity of securing the 

incident scene and protecting people 

and the environment. Incident investigations must be conducted by personnel knowledgeable in the process involved, investigation techniques, and 

other specialties that are relevant or 

necessary. 

(a) The investigation of an incident 

must address the following: 

(1) The nature of the incident; 

(2) The factors (human or other) that 

contributed to the initiation of the incident and its escalation/control; and 

(3) Recommended changes identified 

as a result of the investigation. 

(b) A corrective action program must 

be established based on the findings of 

the investigation in order to analyze 

incidents for common root causes. The 

corrective action program must: 

(1) Retain the findings of investigations for use in the next hazard analysis update or audit; 

(2) Determine and document the response to each finding to ensure that 

corrective actions are completed; and 

(3) Implement a system whereby conclusions of investigations are distributed to similar facilities and appropriate personnel within their organization. 

§ 250.1920 What are the auditing requirements for my SEMS program? 

(a) Your SEMS program must be audited by an accredited ASP according 

to the requirements of this subpart and
