Oil and Gas and Sulphur Operations in the Outer Continental 
Shelf--Incorporate API RP 65 for Cementing Shallow Water Flow Zones

AGENCY: Minerals Management Service (MMS), Interior.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: MMS is incorporating by reference the First Edition of the 
American Petroleum Institute's Recommended Practice (RP) for Cementing 
Shallow Water Flow (SWF) Zones in Deep Water Wells (API RP 65) into MMS 
regulations. From 1987 to 2004, at least 113 Outer Continental Shelf 
(OCS) wells encountered SWF to varying degrees. While the majority of 
these wells experienced SWF to only a minor degree, there were 
instances of severe encounters resulting in abandonment of well sites 
and loss of wells. This action establishes best practices for cementing 
wells in deep water areas of the OCS that are prone to SWF.

EFFECTIVE DATE: March 30, 2007. The incorporation by reference of the 
publication listed in the regulation is approved by the Director of the 
Federal Register as of March 30, 2007.

FOR FURTHER INFORMATION CONTACT: Kirk Malstrom, Office of Offshore 
Regulatory Programs, Regulations and Standards Branch at (703) 787-
1751.

SUPPLEMENTARY INFORMATION:
    Background: Since 1987, OCS operators have reported encountering 
SWF problems while drilling in specific areas of the Gulf of Mexico 
(GOM). Between 1987 and 2004, MMS is aware of at least 113 wells, 
drilled by approximately 25 different operators, that encountered 
problems with SWF. General information on SWFs, and maps showing the 
location of areas in the GOM that have had documented cases of SWF, can 
be viewed at our Web site: http://www.gomr.mms.gov/homepg/offshore/safety/wtrflow.html.
    This final rule updates the requirements for cementing operations 
in 30 CFR Part 250 Subpart A--General, and Subpart D--Oil and Gas 
Drilling Operations. Subpart A is amended to incorporate by reference 
``API RP 65, Recommended Practice for Cementing SWF Zones in Deep Water 
Wells,'' First Edition, September 2002. Subpart D is amended by adding 
new subparagraph (e) to Sec.  250.415, detailing when API RP 65 is to 
be evaluated by an operator in designing a cementing program. Some of 
the key points of this final rulemaking include the following:
    <bullet> Use of this standard is not warranted for every OCS well, 
or for all casing strings in a particular well. Its use is limited to 
situations where there is a risk of encountering a SWF based upon past 
drilling activity, seismic data or interpretation, or correlation of 
data from offset wells in water depths greater than 500 feet (SWF has 
not been encountered in wells in water depths less than 500 feet).
    <bullet> The risk associated with encountering a SWF is 
characterized in one of two ways: (1) An area with an unknown SWF 
potential, or (2) an area known to contain a SWF hazard.
    <bullet> For purposes of this final rule, these terms are defined 
as follows:

    <bullet> An area with an unknown SWF potential means a zone or 
geologic formation where neither the presence nor absence of potential 
for a SWF has been confirmed.
    <bullet> An area known to contain a SWF hazard means a zone or 
geologic formation for which drilling has confirmed the presence of 
SWF.

    <bullet> Use of this standard is limited to water depths greater 
than 500 feet for areas with an unknown SWF potential or areas known to 
contain a SWF hazard. Data available to the MMS on the 113 wells that 
have encountered SWF show that the water depths for these wells ranged 
from approximately 500 feet to 9,675 feet, with an average water depth 
of 3,560 feet.
    <bullet> As part of an operator's Application for Permit to Drill 
(Form MMS-123), a statement needs to be included concerning how API RP 
65 was evaluated by the operator. The operator must also detail which 
of the cementing techniques from this standard were used as part of the 
cementing program for a well drilled in either ``areas with an unknown 
SWF potential'' or ``areas known to contain a SWF hazard.'' This 
information will be evaluated by MMS during the review of the 
application for permit to drill, and discussed with the operator as 
appropriate.
    <bullet> Particular attention should be placed on evaluating, 
designing, and implementing the cementing programs of both the surface 
and conductor casing strings in wells requiring review under API RP 65. 
Data available to the MMS on the 113 wells that have encountered SWF 
show that the tops of the SWF zones ranged from approximately 450 feet 
below mud line to 3,005 feet below mud line, with an average depth of 
encounter of 1,305 feet below mud line. These depths are typical of the 
setting depths of either conductor or surface casings.
    Comments on the Rule: On May 22, 2006, MMS published a proposed 
rule (71 FR 29280) to incorporate API RP 65. The public comment period 
ended on July 21, 2006. MMS received six comments on the proposed rule. 
All the comments came from companies or organizations working in the 
oil and gas industry, including ExxonMobil, BP, Devon, BJ Services 
Company, Schlumberger, and the Offshore Operators Committee (OOC). A 
majority of the comments addressed similar issues mostly on the bias 
toward using foam cement to address the SWF issue in sections of the 
RP. Other comments expressed concern that singling out a specific 
cementing technique hinders new methods and technology development, and 
that this RP is not appropriate for other cementing applications. You 
may view these comments on MMS' Public Connect on-line commenting 
system at: http://www.mms.gov/federalregister/PublicComments/APIRP65.htm.
    Discussion of Comments:
    Comment: Five out of the six comments wanted MMS to omit appendix F 
of API RP 65. The comments suggest omitting this appendix due to a 
perceived bias toward use of foam cementing. At the time the RP was 
developed, foam was the best available cement system for use in 
combating SWFs. Since development of this standard, new options have 
been developed that are similarly efficient, i.e., non-compressible 
systems. A few comments also recommend omitting appendices D and E due 
to bias toward foam cement.
    Response: MMS agrees that there appears to be a bias toward the use 
of foam cement in appendices D, E, and F. However, under this final 
rulemaking, MMS does not require a company to comply with the 
provisions contained in these appendices or submit any information 
related to these appendices. MMS views the appendices in this RP as 
examples and background information. With specific reference to 
appendix F, even with the apparent bias towards use of foam cement, MMS 
still views the cementing matrix as a useful tool that can help a 
company evaluate the performance of their cement jobs and improve upon 
subsequent cement operations.
    Comment: One comment provided further recommendations and alternate 
language to change sections 11.1, 11.2, and 11.3 of the RP to eliminate 
bias towards foam cement.

[[Page 8901]]

    Response: MMS does not have the authority to change an API 
document. While MMS could elect not to incorporate by reference 
specified provisions of the document, it has instead opted to 
incorporate API RP 65, First Edition (September 2002) in its entirety. 
API updates these recommended practices periodically through a 
consensus-based process. MMS believes it best that the changes 
suggested by this commenter be proposed to the API review committee so 
that they can be considered by a cross-section of industry. If the 
proposals are adopted by API, and incorporated into a revised edition 
of this RP, MMS would then have the option to consider incorporating 
the revised edition into the regulations.

Procedural Matters

Regulatory Planning and Review (Executive Order (E.O.) 12866)

    This final rule is not a significant rule as determined by the 
Office of Management and Budget (OMB), and is not subject to review 
under E.O. 12866.
    (1) The final rule will not have an annual effect of $100 million 
or more on the economy. It will not adversely affect in a material way 
the economy, productivity, competition, jobs, the environment, public 
health or safety, or State, local, or tribal governments or 
communities.
    The economic analysis prepared by the MMS indicates that, if the 
techniques included in API RP 65 are evaluated by operating companies 
in the planning phases of wells drilled in Areas with an Unknown SWF 
Potential or Areas Known to Contain a SWF Hazard, this process will 
increase the planning costs associated with these wells by no more than 
$20,000 per well (industry estimate). This cost includes planning 
associated with a full range of SWF mitigation measures. The measures 
include casing centralization; pipe movement; use of light weight 
cements such as a foam system; use of non-compressible systems; proper 
mud circulation prior to cementing; site selection; the drilling of 
pilot holes; setting extra strings of casing; use of measurement while 
drilling technology; pressure while drilling technology; and use of a 
drilling riser for shallow sections of a deep water well. Today, most 
lessees conducting operations in SWF-prone areas already use most of 
these techniques. As a result, additional costs associated with 
implementing these techniques under this final rule will be negligible.
    Based on information available to MMS, there have been a total of 
1,275 wells drilled on the OCS in water depths of 500 feet or greater 
during the period 2000-2004. The cost to industry over the past 5 years 
for SWF mitigation would have been approximately $25.5 million ($20,000 
per well x 1,275 wells = $25.5 million) if the evaluations required for 
this final rule were conducted prior to drilling all of these wells. In 
reality, a significant number of the 1,275 wells would have been 
located in areas known to be free of SWF, and would not have required 
an operating company to implement the techniques included in API RP 65 
as part of their well planning efforts, resulting in a significantly 
lower cost to the offshore industry.
    Using the well data trends from 2000-2004, in water depths greater 
than 500 feet, MMS estimates an average of 200 wells will be drilled 
per year. Using the average of 200 wells, the estimated annual cost to 
industry will be approximately $4 million ($20,000 per well x 200 wells 
= $4 million). Based on actual drilling figures, estimated total well 
costs are in excess of $40 million per well. Industry estimates of 
$20,000 per well for SWF mitigation represents only 0.05 percent of 
total well costs. The possible consequences of SWF, well abandonment, 
or well loss are far more severe than the 0.05 percent of well costs 
for SWF mitigation.
    For the above reasons, the final rule will have a minor economic 
effect on the offshore oil and gas industry.
    (2) The final rule will not create a serious inconsistency or 
otherwise interfere with action taken or planned by another agency. It 
will not change the relationships of the OCS oil and gas leasing 
program with other agencies' actions.
    (3) This final rule will not alter the budgetary effects of 
entitlements, grants, user fees or loan programs, or the rights or 
obligations of their recipients. The changes proposed in this rule are 
strictly planning requirements for specific well cementing processes to 
prevent accidents and environmental pollution on the OCS.
    (4) This final rule will not raise novel legal or policy issues.

Regulatory Flexibility Act (RFA)

    The Department certifies that this final rule will not have a 
significant economic effect on a substantial number of small entities 
under the RFA (5 U.S.C. 601 et seq.).
    The changes in the final rule will affect lessees and operators of 
leases on the OCS. This could include about 130 active Federal oil and 
gas lessees. Small lessees that operate under this rule fall under the 
Small Business Administration's (SBA) North American Industry 
Classification System (NAICS) codes 211111, Crude Petroleum and Natural 
Gas Extraction, and 213111, Drilling Oil and Gas Wells. For these NAICS 
code classifications, a small company is one with fewer than 500 
employees. Based on these criteria, an estimated 70 percent of these 
companies are considered small. This final rule will therefore affect a 
substantial number of small entities.
    As previously stated, there have been a total of 1,275 wells 
drilled on the OCS in water depths of 500 feet or greater during the 
period 2000-2004. Of the total 1,275 wells drilled, 1,107 were drilled 
by large businesses and 168 by small businesses. The 168 wells were 
drilled by a total of 15 small businesses. The 1,107 large business 
wells correspond to 87 percent of all wells drilled, leaving 13 percent 
as small business wells.
    The final rule will have a minor economic effect on the oil and gas 
offshore lessees and operators on the OCS, regardless of company size. 
This is due to the relatively small SWF mitigation costs in relation to 
the high drilling costs. Because of the high potential costs of SWF, 
well abandonment, or well loss, in the overwhelming majority of cases 
operators choose to perform improved and safer well cementing 
procedures on their own initiative, not because of MMS safety 
requirements. The final rule will add relatively little to the cost of 
a well cementing procedure. Thus, there will not be a significant 
impact on a substantial number of small entities under the RFA (5 
U.S.C. 601 et seq.). The final rule will not cause the business 
practices of any of these companies to change.
    Your comments are important. The Small Business and Agriculture 
Regulatory Enforcement Ombudsman and 10 Regional Fairness Boards were 
established to receive comments from small businesses about Federal 
agency enforcement actions. The Ombudsman will annually evaluate the 
enforcement activities and rate each agency's responsiveness to small 
business. If you wish to comment on the actions of MMS, call 1-888-734-
3247. You may comment to the Small Business Administration without fear 
of retaliation. Disciplinary action for retaliation by an MMS employee 
may include suspension or termination from employment with the DOI.

Small Business Regulatory Enforcement Fairness Act (SBREFA)

    The final rule is not a major rule under the SBREFA (5 U.S.C. 
804(2)). This final rule:
    a. Will not have an annual effect on the economy of $100 million or 
more.
    b. Will not cause a major increase in costs or prices for 
consumers, individual industries, Federal, State, or local government 
agencies, or geographic regions.
    c. Will not have significant adverse effects on competition, 
employment, investment, productivity, innovation, or the ability of 
U.S.-based enterprises to compete with foreign-based enterprises. 
Leasing on the OCS is limited to residents of the U.S. or companies 
incorporated in the U.S. This final rule will not change that 
requirement.

Unfunded Mandates Reform Act (UMRA)

    This final rule will not impose an unfunded mandate on State, 
local, or tribal governments or the private sector of more than $100 
million per year. The final rule will not have a significant or unique 
effect on State, local, or tribal governments or the private sector. A 
statement containing the information required by UMRA (2 U.S.C. 1531 et 
seq.) is not required.

Takings Implication Assessment (Executive Order 12630)

    This final rule is not a governmental action capable of 
interference with constitutionally protected property rights. Thus, MMS 
did not need to prepare a Takings Implication Assessment according to 
E.O. 12630, Governmental Actions and Interference with Constitutionally 
Protected Property Rights.

Federalism (Executive Order 13132)

    With respect to E.O. 13132, this final rule will not have 
federalism implications. This final rule will not substantially and 
directly affect the relationship between the Federal and State 
governments. To the extent that State and local governments have a role 
in OCS activities, this final rule will not affect that role.

Civil Justice Reform (Executive Order 12988)

    With respect to E.O. 12988, the Office of the Solicitor has 
determined that the final rule does not unduly burden the judicial 
system and does meet the requirements of sections 3(a) and 3(b)(2) of 
the Order.

Paperwork Reduction Act (PRA)

    The revisions to 30 CFR 250 refer to, but do not change, 
information collection requirements in current regulations. They impose 
no new reporting or recordkeeping requirements and a submission to OMB 
under Sec.  3507(d) of the PRA is not required. The PRA provides that 
an agency may not conduct or sponsor a collection of information unless 
it displays a currently valid OMB control number. Until OMB approves a 
collection of information and assigns a number, you are not required to 
respond. OMB approved the referenced information collection 
requirements for 30 CFR part 250 under OMB Control Numbers 1010-0114 
(22,538 burden hours), expiration October 31, 2007, and 1010-0141 
(163,714 burden hours), expiration August 31, 2008.

National Environmental Policy Act (NEPA) of 1969

    This rule does not constitute a major Federal action significantly 
affecting the quality of the human environment. MMS has analyzed this 
rule under the criteria of the NEPA and 516 Departmental Manual 6, 
Appendix 10.4C(1). MMS completed a Categorical Exclusion Review for 
this action and concluded that ``the rulemaking does not represent an 
exception to the established criteria for categorical exclusion; 
therefore, preparation of an environmental analysis or environmental 
impact statement will not be required.''

Energy Supply, Distribution, or Use (Executive Order 13211)

    Executive Order 13211 requires the agency to prepare a Statement of 
Energy Effects when it takes a regulatory action that is identified as 
a significant energy action. This final rule is not a significant 
energy action; and therefore, will not require a Statement of Energy 
Effects because it:
    a. Is not a significant regulatory action under E.O. 12866,
    b. Is not likely to have a significant adverse effect on the 
supply, distribution, or use of energy, and
    c. Has not been designated by the Administrator of the Office of 
Information and Regulatory Affairs, OMB, as a significant energy 
action.

Consultation With Indian Tribes (Executive Order 13175)

    Under the criteria in E.O. 13175, we have evaluated this final rule 
and determined that it has no potential effects on federally recognized 
Indian tribes. There are no Indian or tribal lands on the OCS.
