OIL AND GAS REASONABLY 

FORESEEABLE DEVELOPMENT 

(RFD) 

INTRODUCTION 

At the time the 1984 Headwaters RMP was prepared 

little additional leasing was anticipated to take place 

because most available leases had already been 

acquired under existing established leasing regulations 

with appropriate stipulations for special conditions. It 

was also anticipated that a relatively large number of 

permits to drill might be sought, given the accelerated 

level of exploration activity that was being driven by 

economic conditions at the time and relatively new 

discovery of prospects for deep structurally trapped oil 

in the Montana Overthrust Belt. Laws, regulations, and 

rules were in-place to provide guidance with these 

leasing and permitting activities. It was anticipated that 

oil and gas drilling would be a part of the foreseeable 

future of resource development within the Planning 

Area. 

Despite the flurry of exploration activity in the Montana 

Overthrust Belt in 1983, the only two areas of oil and 

gas production were in Teton and Ponderosa counties, 

east of the Rocky Mountain Front in areas that have 

since been removed from the Planning Area. 

The Reasonably Foreseeable Development scenario is 

an estimate of oil and gas activity expected because of 

resumed oil and gas leasing in the Planning Area. The 

scenario is hypothetical in that drilling may occur 

anywhere in the planning area where an oil and gas 

lease allowing surface occupancy is issued. Actual 

drilling proposals that result from leasing, if any, will 

likely differ in location from those anticipated by this 

RFD scenario. It is also possible that leasing could 

result in either more or fewer drilling proposals than 

presented in the scenario. 

The RFD scenario attempts to portray the most 

reasonable and likely number of wells expected from a 

leasing decision on the Butte Field Office Planning 

Area. It is derived from knowledge of the USGS plays, 

Energy Information Administration price forecasts, oil 

and gas occurrence and development potential 

classifications for the Planning Area, and historical 

activity. 

Development potential is a ranking system, which is 

created so planners can evaluate the potential 

cumulative impacts of an oil and gas leasing decision 

on a designated area. BLM petroleum geologists rank 

the development potential of the planning area based on 

the probability, at this point in time, of oil and gas 

drilling occurring in the future. It is important to 

understand that development potential is a dynamic 

ranking system, which changes with time as new data 

and ideas become available. The development potential 

can also change as a function of the economics of oil 

supply and demand. 

OCCURRENCE AND DEVELOPMENT 

POTENTIAL 

Occurrence and Development Potential 

Rankings 

BLM staff geologists have classified the potential for 

occurrence and development of oil and gas resources 

within the Butte Field Office Planning Area. Their 

analysis is based on bedrock geologic mapping, 

geophysical data, and 110 oil and gas wells drilled in 

Planning Area. A summary of the geology, for each of 

the 1:100,000 quadrangles used for discussion and 

development of the occurrence and development 

potential sections of this report can be found in 

unpublished reports by Long (1990a-h, 1991a-c) that 

are on file in the BLM Montana State Office. The 

potential for oil and gas resource development within 

the Planning Area is shown on Figure A-1. 

On Figure A-1, areas have been designated as having 

moderate, low, and very low potential for the 

occurrence and development of oil and gas resources. 

As with the occurrence potential, there are no areas of 

“high” development potential within the Butte Field 

Office Planning Area. High development potential 

areas occur only within proven producing petroleum 

provinces or in areas with a significant number of 

hydrocarbon “shows”. Areas of moderate development 

potential have a significant thickness of sedimentary 

section present that includes possible source and 

reservoir rocks. An area having a low potential for 

development has a thin sedimentary section present or 

there is insufficient subsurface data available to analyze 

the potential. It also lacks source or reservoir rocks or is 

metamorphosed. An area of very low development 

potential has no sedimentary section at the surface or 

insufficient data for a different classification. These 

areas also include areas of Federal lands that are 

unavailable for leasing. The principal source of 

information used to determine the development 

potential of the Butte Field Office Planning Area is a 

series of 1:100,000 quadrangles (Long, 1990a-h, 1991ac). 

Development potential is not a prediction of precise 

future drilling locations and should not be used as a 

gauge of future interest or lack of interest in leasing. Oil 

and gas companies have numerous sources of 

proprietary data not available to the BLM (such as 

seismic data or internal geologic reports), which they 

use prior to making financial commitments to lease or 

Butte Draft RMP/EIS 883

drill. Therefore, even though an area is rated as very 

low development potential at this time with a low 

probability for any wells being drilled, a company may 

still be interested in leasing that area, should it be made 

available. 

Drilling Activity Forecast 

In order for the BLM to be able to analyze the effects of 

renewed oil and gas leasing, and possible impacts 

related to exploration, development, and cumulative 

effects, it is necessary to estimate how many wells 

industry might drill in the next 20 years. The following 

RFD scenario has been developed using historical oil 

and gas development, and oil “play” information from 

the USGS, potential development maps and other data 

from BLM files, and a number of other technical 

sources. 

The BLM has mapped the potential for occurrence of 

oil and gas under the Butte Field Office Planning Area 

and the potential for industry to develop those possible 

resources. The classification of development potential 

is depicted on Figure A-1. From these maps and other 

information, including leasing history and past and 

present economics, a forecast of the number of wells 

that might be drilled in the Planning Area on lands of 

all mineral ownerships is made. 

Based on this analysis, an estimate was made that as 

many as fifteen (15) conventional oil and gas wildcat 

wells (exploratory wells drilled in an area with no 

existing production) might be drilled in the Butte Field 

Office Planning Area in the next 15 to 20 years (Table 

1). Of these fifteen (15) wells, it is estimated that eleven 

(11) would be “dry” holes (no economically producible 

oil or gas is discovered). Dry holes would be plugged 

and abandoned with surface reclamation occurring 

shortly afterward. It is further estimated that four (4) of 

the wells could have oil or gas discoveries, two (2) of 

which would become producers with one located on 

either BLM minerals or lands administered by the 

Forest Service, and the other located on privately 

owned mineral lands. Each of the discovery wells 

would probably prompt additional step-out wells. A 

"step-out well" is a well drilled adjacent to or near a 

proven well to establish the limits and continuity of the 

oil or gas reservoir and/or to assist with production. It 

was estimated that a total of eight (8) step-out wells 

would be drilled, two for each discovery. 

In addition to conventional oil and gas wells, it is 

anticipated that as many as 40 wells (Table 1) would be 

drilled for coal bed natural gas in limited and scattered 

areas of known sub-bituminous coal resources located 

Gallatin and Park Counties; most likely in the Trail 

Creek Road area near Bozeman Pass (Livingston and 

Trail Creek Fields). 

The first four general geographic areas within the Butte 

Field Office Planning Area, where conventional oil and 

gas exploration is predicted to occur are shown on 

Figure A-1. Each of the four areas is associated with 

one or more play areas described above in the section 

entitled USGS Hydrocarbon Provinces and Plays. It is 

anticipated that the 15 projected wildcat wells would be 

drilled somewhere within the boundaries of these four 

play areas. (Table 1)

Area # 1 - Area #1 is referred to on Figure A-1 as the 

"Southern Deerlodge Valley Basin Area". This area 

occurs in the southernmost portion of a fault bounded 

Tertiary-aged basin that is located in the Deerlodge 

Valley. Along the eastern edge of this basin volcanic 

rocks obscure a thin section of Tertiary age basin fill 

sediments that in turn overlie Boulder Batholith rocks 

(Long, 1990b). Further to the west within this basin, 

rocks of Miocene to Eocene age have been encountered 

in previous drilling. The rocks are all non-marine and 

consist of sands and gravels of alluvial channels 

interlayered with sand, silt, and clay-rich alluvial 

overbank deposits that are interspersed with finegrained sediments deposited in lakes and marshes. 

These sediments have accumulated in thickness as great 

as 10,000 feet (3,048 meters). Fluvial sandstones are 

thought to be potential reservoir rocks with the source 

of oil and gas being either organic material buried 

deeply in the Tertiary basin proper or having migrated 

from Paleozoic sediments that lie beneath the Tertiary 

basin fill or across the basin margin faults. The thickest 

and most complete section of Paleozoic rocks lies to the 

west of the holes shown in the area of moderate 

potential (Figure A-1). Two holes have been drilled 

within the Planning Area and five more have been 

drilled in a similar geologic setting immediately to the 

north of this area. These holes were drilled from 6,411 

feet (1,954 meters) to as much as 11,774 feet (3,589 

meters) deep (Long, 1990b). One well, the Amoco 1 

Johnson, encountered good oil shows in the Tertiary 

basin fill sediments. Two exploratory wells for oil and 

gas might be expected in the next 15-20 years in this 

portion of the Planning Area. They would probably lie 

to the north and west of the holes shown, closer to basin 

margin faults with potentially thicker sequences of 

Paleozoic source rocks underlying Tertiary basin fill

adjacent to the fault zone. As only about 20 percent of 

the land within this basin is underlain by federally 

administered subsurface mineral rights and more than 

87 percent of the surface is privately owned (no BLM 

surface ownership), it is unlikely that any of the wells 

would be drilled on federal lands. It is also unlikely that 

there would be any discoveries in this area. 

Area #2 - Area #2 is referred to on Figure A-1 as the 

“Imbricate Thrust Zone”. The area occurs both to the 

north and east of Helena, Montana, in a sequence of 

sediments that are thick and structurally thickened by 

imbricate thrust faulting associated with the Eldorado 

and Reff thrust faults. Here Cenozoic sediments 

unconformably overly Mesozoic and Paleozoic 

sediments, and basement Precambrian-age rocks. Only 

two oil and gas wells have been completed in this area 

between 1975 and 1990. One, the Getty well, was 

spudded in Mississippian Lodgepole Limestone and 

drilled in Paleozoic sediments to a final depth of 12,731 

feet (3,880 meters). It encountered eleven thrust faults 

that repeated the Lodgepole Limestone eight (8) times. 

The other well drilled by Arco, was completed at a 

depth of 5,002 feet (1,525 meters). It was spudded in 

the Precambrian Belt sediments and drilled through the 

Eldorado thrust fault at 2,500 feet (762 meters) and into 

good potential host rocks of the Mississippian Madison 

Formation, in which it remained until the bottom of the 

hole. Unocal drilled a third, very deep (17,818 feet or 

5,431 meters) dry well, in the northern portion of this 

area (Table 1). The recently drilled Suncor well, 

described in the Exploration Drilling section, is present 

in the northernmost portion of the Planning Area on the 

Sieban Ranch near Flesher Pass. Area 2 is thought to 

have moderate oil and gas potential because of the 

significant thicknesses of Paleozoic sediment (known to 

contain good reservoir and source rocks) in a zone that 

is complicated and repeated by thrust faulting that can 

create stratigraphic and structurally controlled traps by 

folding and the juxtapositioning of rocks across the 

thrust faults. Five wells are expected to be drilled in this 

area within the next 15-20 years. One of these wells is 

predicted to have significant shows of oil and gas 

warranting offset drilling of two additional wells. The 

tests in this area can be deep and expensive, and the 

structure complex and difficult to understand. Most of 

the BLM lands in Area 2 occur in two continuous 

blocks and when combined with split estate lands with 

federal minerals make up about 20% of the entire area. 

The large contiguous area in the northeastern portion of 

Area 2 lies to the east of the intensely imbricated thrust 

fault zone that has seen exploration drilling along the 

western margin of this play area. It is possible that one 

or more of the five exploration wells could be drilled on 

federal lands, but with a small likelihood of a 

discovery. 

Areas #3 - Area #3 is referred to as the “Helena Salient 

Gas Play Zone”. This zone occurs over a very large 

area in the east-central portion of the Planning Area 

(Figure A-1). The area is underlain by Jurassic (locally 

Cretaceous) through Cambrian age rocks in a sediment 

package as much as 10,000 feet (3,048 meters) thick. 

The area has been thrust faulted along north-south 

structures that have resulted in a series of parallel northsouth anticlines and synclines. The entire sequence can 

be overlain by 1,600 feet (488 meters) (in the west) to 

as much as 5,000 feet in the east (1,524 meters) of 

volcanics in the Elkhorn Mountain area. Hydrocarbons 

have been reported from a well along the east flank of 

the Mauldow Basin in a well drilled to 11,592 feet 

(3,533 meters) into Precambrian rock. Gas shows were 

reported from Cambrian sediments at a depth of about 

11,000 feet (3,353 meters). Elsewhere in the area, 

several shallow wells (<1,005 feet or 306 meters) had 

oil shows in the Cambrian and Devonian portion of the 

section. It may be necessary to drill through sub-thrust 

Precambrian rocks to find deep potential reservoir rocks 

(10,000-12,000 feet or 3,048-3,658 meters) in the 

western portion of the area and 15,000-25,000 feet 

(4,572-7,620 meters) in the eastern portion of the area. 

Areas of moderate potential in the Helena Salient area 

are coincident with the location of mapped anticlinal 

structures. Three wells have been drilled since 1975, 

one of which was a dry hole drilled in 1991. Four wells 

are anticipated in the next 15-20 years, additional 

shows are expected, and one discovery well is predicted 

with one or two offset wells (limited number of wells 

because of depth and cost of drilling). Although the 

BLM owns surface and mineral rights to some 37,000 

acres, about 20% of Area 3) more than half of that area 

lies within the Limestone Hill Montana Army National 

Guard Training area, which is contaminated with 

unexploded military ordinance and the subject of a 

current Legislative EIS that proposes to withdraw the 

area from future mineral entry. It is unlikely that any 

federal wells would be drilled in Area 3. Mineral 

withdrawal normally does not apply to access for the 

Mineral Leasing Act, therefore access for fluid mineral 

drilling within the Limestone Hills Training Area may 

be possible. Assuming the issue involving safe access 

with respect to unexploded ordinance can be resolved 

one well may be drilled on Federal lands within the 

Limestone Hills Training Area. 

Area #4 - Area #4 consists of the “Crazy Mountain Oil 

and Gas Play” on Figure A-1. This area occupies most 

of the northern portions of Gallatin and Park Counties 

in the easternmost portion of the Planning Area as a 

broad extensive area of potential oil and gas resources. 

In particular the area east of Livingston appears to have 

a moderate potential. Non-marine Upper Cretaceous 

rocks of the Livingston group cover most of the area 

and range in thickness from 9,000 feet (2,743 meters) 

(in the west between Belgrade and Bozeman) to about 

1,000 feet (305 meters) along the eastern Planning Area 

boundary. Concealed beneath these sediments are 

Cretaceous marine sediments and beneath them a 

complete sequence of Paleozoic sediments that have 

Butte Draft RMP/EIS 885 
Appendix L 

locally been thrust faulted, repeating the section. In this 

area, the Superior 22-25 Windsor well was drilled on 

the Hunter Anticline to a depth of 8,990 feet (2,740 

meters). This well encountered gas in the Cretaceous 

Eagle sandstone at 1,950 feet (594 meters). Thrust 

faults were encountered in this well that bottomed in 

Cambrian sediments, suggesting that multiple stacked 

targets may be present at depths of 10,000-20,000 feet 

(3,048-3,658 meters), in addition to the shallow 

Cretaceous gas targets. Numerous anticlines have been 

identified in the section that may represent structural 

traps. Six wells have been drilled since 1975 and none 

in recent years (post 1990). It is envisioned that four (4) 

wells may be drilled in this area including one deep 

well east of Livingston around the interstate and three 

shallow wells exploring for Cretaceous gas resources. It 

is envisioned that the deep well and one of the shallow 

wells would yield discoveries that warranted step-out 

drilling of two holes for each discovery. These wells 

will be either on National Forest System Lands, or more 

likely, on lands with private mineral rights that make up 

about 94% of Area 4. 

Area #5 - Other places within the Butte Field Office 

Planning Area, where gas exploration is predicted to 

occur are areas of coal bed natural gas potential 

associated with known sub-bituminous coal deposits. 

Areas of coal bed natural gas potential where activity is 

predicted in the reasonably foreseeable development 

scenario occur in one area labeled Area 5 on Figure A1. Overall it is envisioned that initially ten exploration 

wells would be drilled, and that six of these would 

discover coal bed natural gas resources that would 

warrant the drilling of an additional 24 step-out wells to 

develop the resources (Table 1). These would all likely 

be non-federal wells. 

The reasonably foreseeable development scenarios for 

these areas have been developed for Gallatin and Park 

Counties by the Bureau of Land Management and the 

Montana Board of Oil and Gas Conservation (BLM and 

MBOGC, 2003). It has been estimated that as many as 

five to 15 wells would be drilled in Gallatin County and 

that of these, as many as five to 10 would be producing 

wells from one field (BLM and State of Montana, 

2003). Two locations were permitted for exploration 

drill holes for coal bed natural gas on untested private 

land in section 13 and 14 of T. 2 S., R. 7E. in the Trail 

Creek coal field by the state of Montana in 2001. The 

wells were scheduled to be drilled to depths of about 

5,500 feet (1,676 meters) to test the Upper Cretaceousage Telegraph Creek-Eagle Sandstone interval along 

the crest of an anticlinal structure. However, legal 

challenges involving Gallatin County and the formation 

of a local zoning district tied up the drilling process and 

the permits to drill expired in January of 2003. Legal 

issues need to be resolved in the Trail Creek area before 

drilling of this previously permitted well might be 

undertaken. The BLM administers a small number of 

isolated tracts of split estate minerals in the Trail Creek 

coal deposit area, but most of the exploration potential 

lies on private land with separated surface and mineral 

estate. Assuming that natural gas prices remain high, it 

is likely that exploration drilling will ultimately be 

permitted on private land in this area. 

In Park County it has been estimated that as many as 

10-25 coal bed natural gas exploratory wells might be 

drilled with as many as 10 to 20 becoming producing 

wells also from one field (BLM and state of Montana, 

2003). 

Surface Disturbance Impacts 

This section of the Reasonable Foreseeable 

Development Scenario describes the anticipated 

disturbances associated with the Drilling Activity 

Forecast predicted in the preceding section. Table 2 

describes the tasks involved and the surface 

disturbances that are likely to result from the successful 

and unsuccessful drilling of conventional and coal bed 

natural gas wildcat wells, development or step-out 

drilling, and field production activities of the RFD 

drilling forecast. The number of acres of disturbance 

estimated relies on data derived from wildcat well 

drilling within the Butte Field Office Planning area and 

on existing small scale production from fields 

developed within the Overthrust belt of Montana and 

from data presented in the Final State-wide Oil and Gas 

EIS (BLM and MBOGC, 2003). Reclaimed acres 

(regraded and seeded) are assumed to be stabilized after 

two years.

PROCEDURES IN OIL AND GAS 

RECOVERY AND OPERATIONS 

GEOPHYSICAL OPERATIONS 

Oil and gas reservoirs are discovered by either direct or 

indirect exploration methods. Direct methods include 

mapping of surface geology, observing oil or gas seeps, 

and gathering information on hydrocarbon shows 

observed in drilling wells. Indirect methods include 

various types of geophysical exploration such as 

seismic, gravity, and magnetic surveys, which use 

remote data gathering techniques to delineate subsurface 

structures or lithologic changes that are not directly 

observable, but that may contain or trap oil and gas. 

Data is often acquired using equipment mounted on 

surface vehicles or aircraft. Information from 

geophysical exploration can lead oil companies or others 

to request that lands be offered for lease, or assist in the 

selection of drill sites on existing leases. However, a 

federal oil and gas lease is not required in order to 

conduct geophysical operations. Existing road systems 

are used where available. Roads may be cleared of 

vegetation and loose rocks to improve access for trucks 

if the permit allows that action. 

Blading and road construction for seismic operations are 

not usually allowed so that environmental impacts are 

minimized. In areas with rugged terrain or without 

access roads, and during certain seasons of the year, 

seismic work is conducted by helicopter rather than by 

ground vehicles. Other geophysical operations that do 

not cause additional surface disturbance include remote 

sensing, and gravity, and aeromagnetic surveying. 

Geophysical Permitting Procedures and 

Regulations 

Geophysical operations on and off an oil and gas lease 

are reviewed by the Federal Surface Management 

Agency (SMA), which can include the BLM, Bureau of 

Reclamation, or U.S. Forest Service (USFS). Close 

cooperation between the operator and the managing 

agency during geophysical operations minimizes surface 

impacts and protects other resources. 

Notification Process 

Geophysical operations on public lands are reviewed by 

the BLM. Geophysical exploration on public lands 

requires review and approval following the procedures 

in 43 CFR Subparts 3150, 3151, and 3154. In the Butte 

Field Office, the Field Manager is authorized to approve 

geophysical operations. The responsibilities of the 

geophysical operator and the Field Manager during 

geophysical operations are described below. 

Geophysical Operator 

The operator is required to file a Notice of Intent to 

Conduct Oil and Gas Exploration Operations (form 

3150-4) for operations on public lands administered by 

the BLM. Maps (preferably 1:24,000 scale topographic 

maps) showing the location of the proposed lines, access 

routes and ancillary facilities must accompany the 

Notice of Intent. When the Notice of Intent is filed, the 

authorized officer may request a prework conference or 

field inspection. Special requirements or procedures that 

are identified by the authorized officer are included in 

the Terms and Conditions for Notice of Intent to 

Conduct Geophysical Exploration (form 3150-4 and a 

copy of the state requirements). Any changes in the 

original Notice of Intent must be submitted in writing to 

the authorized officer. Written approval must be secured 

before activities proceed. 

Bonding of the operator is required. A copy of proof of 

satisfactory bonding shall accompany the Notice of 

Intent. Proper bonding may include a $5,000 individual, 

$25,000 statewide, or $50,000 nationwide geophysical 

exploration bond. In lieu of an exploration bond, a 

statewide or nationwide oil and gas bond may be used if 

it contains a rider for geophysical exploration. The 

operator is required to comply with applicable federal, 

state, and local laws such as Federal Land Policy and 

Management Act of 1976, the National Historic 

Preservation Act of 1966, and the Endangered Species 

Act of 1973, as amended. Earth-moving equipment shall 

not be used without prior approval. Operators may be 

required to submit an archeological evaluation and the 

agency provide NEPA documentation for cultural and 

wildlife resources if dirt work or other surface 

disturbance is contemplated, or if there is reason to 

believe that these resources may be adversely affected. 

When geophysical operations have been completed 

including any required reclamation or rehabilitation, the 

operator is required to file a Notice of Completion (form 

3150-5) including certification that all terms and 

conditions of the approved Notice of Intent have been 

fulfilled. The operator must also submit a map that 

shows the actual line location, access route, and other 

survey details. 

BLM Field Manager (authorized officer) 

The authorized officer is required to contact the operator 

within five working days after receiving the Notice of 

Intent to explain the terms of the notice, including the 

“Terms and Conditions for Notice of Intent to Conduct 

Geophysical Exploration,” current laws, and BLMadministrative requirements. At the time of the prework 

conference or field inspection, written instructions or 

orders are given to the operator. The authorized officer 

is responsible for the examination of resource values to 

determine appropriate surface protection and 

reclamation measures. Compliance inspections during 

the operation ensure that stipulations are followed. The 

Butte Draft RMP/EIS 889 
Appendix L 

authorized officer is required to make a final inspection 

following filing of the Notice of Completion. 

Compliance inspections upon completion of work ensure 

that required reclamation is properly completed. When 

reclamation is approved, obligation against the 

operator’s bond is released. The BLM has 30 days after 

receipt of the Notice of Completion to notify the 

operator whether the reclamation is satisfactory or if 

additional reclamation work is needed. Bonding liability 

will automatically terminate within 90 days after receipt 

of the Notice of Completion unless the authorized 

officer notifies the operator of the need for additional 

reclamation work. 

State Standards 

Geophysical operators register with the state through the 

County Clerk and Recorder’s office. State regulations 

include requirements for permitting geophysical 

activities such as shothole locations, drilling techniques, 

plugging techniques, bonding, and reclamation. 

Mitigation 

When a geophysical Notice of Intent is received, 

restrictions may be placed on the application to protect 

resource values or to mitigate impacts. Many of these 

requirements may be the same as the oil and gas lease 

stipulations adopted in the RMP. Other less restrictive 

measures may be used when impacts to resource values 

will be less severe. This is due in part to the temporary 

nature of geophysical exploration. Seasonal restrictions 

may be imposed to reduce conflicts with wildlife, 

watershed damage, and hunting activity. The decisions 

concerning the level of protection required are made on 

a case-by-case basis when a Notice of Intent is received. 

LEASING PROCESS 

Federal oil and gas leasing authority is found in the 1920 

Mineral Leasing Act, as amended, for public lands and 

the 1947 Acquired Lands Leasing Act, as amended, for 

acquired lands. Leasing of federal oil and gas is affected 

by other acts such as National Environmental Policy Act 

of 1969, the Wilderness Act of 1964, National Historic 

Preservation Act of 1966, the Endangered Species Act of 

1973, Federal Land Policy and Management Act of 

1976, and the Federal Onshore Oil and Gas Leasing 

Reform Act of 1987. Regulations governing federal oil 

and gas leasing are contained in 43 CFR Part 3100 with 

additional requirements and clarification found in 

Onshore Operating Orders and Washington office 

manuals, handbooks and instruction memorandums. 

The 1920 Mineral Leasing Act provides that all public 

lands are open to oil and gas leasing unless a specific 

order has been issued to close an area. Leasing 

procedures for oil, conventional gas, and coal bed 

natural gas are the same. 

The lease grants the right to explore, extract, remove, 

and dispose of oil and gas deposits that may be found in 

the leased lands. The lessee may exercise the rights 

conveyed by the lease subject to the lease terms and 

attached stipulations, if any. 

Lease rights may be subject to lease stipulations and 

permit approval requirements. Stipulations and permit 

requirements describe how lease rights are modified. 

Lease constraints or requirements may also be applied to 

applications for permit to drill on existing leases 

provided the constraints or requirements are within the 

authority reserved by the terms and conditions of the 

lease. The stipulations and conditions of approval must 

be in accordance with laws, regulations, and lease terms. 

The lease stipulations and permit conditions of approval 

allow for management of federal oil and gas resources in 

concert with other resources and land uses. The BLM 

planning process is the mechanism used to evaluate and 

determine where and how federal oil and gas resources 

will be made available for leasing. In areas where oil and 

gas development may conflict with other resources, the 

areas may be closed to leasing. Areas where oil and gas 

development could coexist with other land uses or 

resources will be open to leasing. Leases in these areas 

will be issued with standard lease terms or with added 

stipulations based upon decisions in the land use 

document. Added stipulations are a part of the lease only 

when environmental and planning records demonstrate 

the necessity for the stipulations (modifications of the 

lease). 

Currently, leases are issued as either competitive leases 

or noncompetitive leases with 10-year terms. 

Competitive leases will be sold to the highest qualified 

bidder at oral auctions that are held at least quarterly. 

Tracts that receive no bid at the sale are available for the 

filing of noncompetitive offers for two years following 

the sale. All offers filed the day after the sale (referred to 

as day-after-the-sale filings) are considered 

simultaneously filed. This means that if there is more 

than one offer filed for a specific parcel the day after the 

sale, a drawing must be held to determine the priority on 

multiple offers. Noncompetitive offers filed after that 

time are on a first-come first-served basis. If there are no 

offers filed for a parcel for the two-year period after the 

sale, the lands must be nominated again for competitive 

leasing. Rental payments for these leases will be $1.50 

per acre for the first 5 years and $2.00 per acre thereafter 

until production is established. If the lessee establishes 

hydrocarbon production, the leases can be held for as 

long as oil or gas is produced. The royalty rate for leases 

issued following the 1987 Oil and Gas Leasing Reform 

Act is 12-1/2 percent one-half of which is returned to the 

State of Montana on public domain lands (not acquired 

lands). Minimum royalty is the same amount as the 

rental. Future interest leases are available for entire or 

fractional mineral estates that have not reverted to 

federal ownership. These are minerals that are reserved 

by the grantor for a specific period of time in warranty 

deeds to the United States. Any future interest leases 

890 Butte Draft RMP/EIS 
Fluid Minerals 

may be obtained only through the competitive bidding 

process and are made effective the date of vesting of the 

minerals with the United States. 

Resource Management Plan 

Maintenance 

New information may lead to changes in existing 

resource inventories. New use areas and resource 

locations may be identified or use areas and resource 

locations that are no longer valid may be identified. 

These resources usually cover small areas requiring the 

same protection or mitigation as identified in this plan. 

Identification of new areas or removal of old areas that 

no longer have those resource values will result in the 

use of the same lease stipulation identified in this plan. 

These areas will be added to the existing data inventory 

without a plan amendment. In cases where the changes 

constitute a change in resource allocation outside the 

scope of this plan, a plan amendment would be required. 

Lease Stipulations 

Certain resources in the planning area require protection 

from impacts associated with oil and gas activities. The 

specific resource and the method of protection are 

contained in lease stipulations. Lease stipulations are 

usually no surface occupancy, controlled surface use, or 

timing limitation. A notice may also be included with a 

lease to provide guidance regarding resources or land 

uses. While the actual wording of the stipulations may 

be adjusted at the time of leasing, the protection 

standards described will be maintained. 

Controlled Surface Use 

Use or occupancy is allowed (unless restricted by 

another stipulation), but identified resource values 

require special operational constraints that may modify 

the lease rights. Controlled surface use is used for 

operating guidance, not as a substitute for the no surface 

occupancy or timing stipulations. 

No Surface Occupancy (NSO) 

Use or occupancy of the land surface for fluid mineral 

exploration or development is prohibited in order to 

protect identified resource values. The no surface 

occupancy stipulation includes stipulations which may 

have been worded as No Surface Use and Occupancy,” 

“No Surface Disturbance,” “Conditional No Surface 

Occupancy,” and “Surface Disturbance or Occupancy 

Restriction (by location).” 

Timing Limitation (Seasonal Restriction) 

Prohibits surface use during specified times to protect 

identified resource values. This stipulation does not 

apply to the operation and maintenance of production 

facilities unless the findings of analysis demonstrate the 

continued need for such mitigation and that less 

stringent, project-specific mitigation measures would be 

insufficient. 

PERMITTING 

A federal lessee or operator is governed by procedures 

set forth in the Code of Federal Regulations at 43 CFR 

Part 3160, Onshore Oil and Gas Order No. 1, “Approval 

of Operations on Onshore Federal and Indian Oil I and 

Gas Leases,” issued under 43 Code of Federal 

Regulations (CFR) 3164 and other orders and notices. 

The lessee may conduct lease operations after lease 

issuance. However, proposed drilling and associated 

activities must be approved in advance before beginning 

operations. Therefore, before beginning construction or 

the drilling of a well, the lessee or operator must file an 

Application for Permit to Drill (APD) with the BLM 

Great Falls Oil and Gas Field Station. A copy of the 

application will be posted in the Field Station and Butte 

Field Office, and if applicable, in the office of the 

Surface Management Agency (SMA) for a minimum of 

30 days for review by the public. After 30 days, the 

application can be approved in accordance with (a) lease 

stipulations, (b) Onshore Oil and Gas Orders, and (c) 

Onshore Oil and Gas regulations (43 CFR Part 3160) if 

it is administratively and technically complete. 

Evidence of bond coverage for lease operations must be 

submitted with the application. Bond amount must not 

be less than a $10,000.00 lease bond, a $25,000.00 

statewide bond or a $150,000.00 nationwide bond. 

Pre-drill on-site inspections will be conducted for all 

wells. The inspection makes possible selection of the 

most feasible well site and access road from 

environmental, geological, and engineering points of 

view. The purpose of the field inspection is to evaluate 

the operator's plan, assess the situation for possible 

impacts, and to formulate resource protection 

stipulations. Surface use and reclamation requirements 

are developed during the on-site inspection that is 

usually conducted within 15 days after receipt of the 

Notice of Staking (NOS) or APD. For operations 

proposed on privately-owned surface, if the operator 

after a good-faith effort is unable to reach an agreement 

with the private surface owner, the operator must post a 

bond to cover loss of crops and damages to tangible 

improvements prior to approval of the APD. 

Normally, site-specific mitigations in the form of 

conditions of approval are added to the APD for 

protection of surface and subsurface (including 

groundwater) resource values in the vicinity of the 

proposed activity. The BLM is responsible for preparing 

environmental documentation necessary to satisfy the 

National Environmental Policy Act (NEPA) 

requirements and provide any mitigation measures 

needed to protect the affected resource values. 

Butte Draft RMP/EIS 891 
Appendix L 

Conditions of approval implement the lease stipulations 

and are part of the permit when environmental and field 

reviews demonstrate the necessity for operating 

constraints or requirements. A surface restoration plan is 

part of an approved permit, either an APD or Sundry 

Notice that includes other surface-disturbing activities. 

The authorized officer will act on the application in one 

of two ways: 

Within 30 days after the operator has submitted a 

complete application including incorporating any 

changes that resulted from the onsite inspection the 

BLM will: 

(1) approve the application subject to reasonable 

conditions of approval if the requirements of the 

National Environmental Policy Act (NEPA), National 

Historic Preservation Act (NHPA), Endangered Species 

Act (ESA), or other applicable law have been completed 

and, if on FS lands, FS has approved the Surface Use 

Plan of Operations; or 

(2) notify the operator that it is deferring action on the 

permit. The notice of deferral must specify: 

(a) any action the operator could take that would enable 

BLM to issue a final decision on the application, with FS 

concurrence if appropriate. Actions may include but are 

not limited to; assistance with data gathering or 

assistance with preparation of analyses and documents; 

(b) and if necessary, a list of actions that BLM or the FS, 

if appropriate, need to take, including completing 

requirements of NEPA or other applicable law and a 

schedule for completing these actions. 

The operator has 2 years from the date of the notice of 

deferral to take the action specified in the notice. If all 

analyses required by NEPA, NHPA, ESA and other 

applicable laws have been prepared, BLM and with FS 

concurrence, if appropriate, shall make a decision on the 

permit within 10 days of receiving a report from the 

operator addressing all of the issues or actions specified 

in the deferral notice and certifying that all required 

actions have been taken. If the operator has not 

completed the actions specified in the notice, BLM may 

deny the permit at any time later than 2 years from the 

operator’s receipt of the deferral notice.” 

For drilling operations on lands with state or private 

mineral ownership, the lessee must meet the 

requirements of the mineral owner and the state 

regulatory agency. The BLM does not have jurisdiction 

over nonfederal minerals; however, the BLM has surface 

management responsibility in situations of BLM surface 

over nonfederal mineral ownership. 

When final approval is given by the BLM, the operator 

may begin construction and drilling operations. 

Approval of an APD is valid for one year. If 

construction does not begin within one year, the permit 

must be reviewed prior to approving another APD. 

A Sundry Notice is used to approve other surface and 

subsurface lease operations. When a well is no longer 

useful, the well is plugged and the surface reclaimed. A 

Sundry Notice is also used to approve well plugging and 

reclamation operations, although verbal approval for 

plugging may be given for a well that was drilled but not 

completed for production. 

The period of bond liability is terminated after all wells 

covered by the bond are properly plugged and the 

surface reclaimed. The lands may then become available 

for future leasing. 

APPLICATION FOR PERMIT TO 

DRILL 

Applications for Permit to Drill are approved for the 

Butte Field Office by the supervisor of the Great Falls 

Oil and Gas Field Station. The approved APD includes 

Conditions of Approval, and Informational Notices that 

cite the regulatory requirements from the Code of 

Federal Regulations, Onshore Operating Orders and 

other guidance. 

CONDITIONS OF APPROVAL 

Conditions of approval are mitigation measures that 

implement restrictions in light of site-specific 

conditions. General guidance for conditions of approval 

and surface operating standards is found in the BLM and 

USFS brochure entitled “Surface Operating Standards 

for Oil and Gas Exploration and Development” (USDI, 

BLM1989c) and BLM Manual 9113 entitled “Roads”. 

The BLM commonly applies best management practices 

when approving APDs. The sources of many of these 

may be found in RMP Appendix D at page 4. 

The following mitigation measures may be applied to 

approved permits to drill as conditions of approval. The 

listing is not all-inclusive, but presents some possible 

conditions of approval that may be used in the planning 

area. The wording of the condition of approval may be 

modified or additional conditions of approval may be 

developed to address specific conditions. 

Surface Conditions 

a) The access road on the BLM surface will not be 

bladed unless prior BLM approval is obtained. 

b) The operator will be responsible for weed control on 

the access road, well location, and pipeline for the 

life of the well. 

c) The operator will clean the undercarriage of all rigs 

prior to entering onto the leasehold to reduce the 

chances for noxious weed infestations. 

d) Topsoil is to be removed and stockpiled. Operator 

will be required to cover the topsoil pile to prevent 

the loss of topsoil to wind erosion. Operator must 

cover the topsoil with a biodegradable mesh fabric 

that allows water and air to circulate through the 

892 Butte Draft RMP/EIS 
Fluid Minerals 

topsoil. Operator cannot cover the topsoil with any 

type of impermeable fabric. Operator will be 

responsible for weed control on the topsoil 

stockpile. 

e) Avoid constructing reserve pits in natural 

watercourses or areas of shallow groundwater. 

Water courses include lake beds, gullies, draws, 

streambeds, washes, arroyos, or channels that are 

delineated on a 1:24,000 USGS quadrangle map or 

have a hydrologic connection to streams, rivers, or 

lakes. The reserve pit should normally be located 

entirely in cut material. The preferred method of 

reserve pit construction on steeply sloping sites is to 

locate the pit on the drill pad next to the high wall. 

The pits are constructed totally in cut at such 

locations. If this is not possible, at least 50 percent 

of the reserve pit should be constructed below 

original ground level to help prevent failure of the 

pit dike. Fill dikes should be properly compacted in 

lifts. The necessary degree of compaction depends 

on soil texture and moisture content. The pit should 

be designed to contain all anticipated drilling muds, 

cuttings, fracture fluids, and precipitation while 

maintaining at least 2 feet of freeboard. Pits 

improperly constructed on slopes or poor soil types 

may leak along the plane between the natural 

ground level and the fill. There is a significant 

potential for pit failure in these situations. When 

constructing dikes for pits or impoundments with 

fill embankment, a keyway or core trench should be 

excavated to a minimum depth of 2 to 3 feet below 

the original ground level. The core of the 

embankment can then be constructed with 

compacted, water-impervious material. 

f) Containment structures sufficiently impervious to 

prevent a discharge to waters of the US, such as 

containment dikes, containment walls, drip pans, or 

equivalent protection actions are to be constructed 

and maintained around all qualifying bulk oil 

storage facilities, including tank batteries, 

consistent with the Environmental Protection 

Agency’s Spill Prevention, Control, and 

Countermeasure (SPCC) regulation (40 CFR 112). 

The containment structure must have sufficient 

volume to contain, at a minimum, the content of the 

largest storage tank containing liquid hydrocarbons 

within the facility/battery and sufficient freeboard to 

contain precipitation, unless more stringent 

protective requirements are deemed necessary by 

the authorized officer. Containment dikes are not to 

be constructed with topsoil or coarse, insufficiently 

impervious spoil material. Containment is strongly 

suggested for produced water tanks. Chemicals 

should be placed within secondary containment and 

stored so that the containers are not in contact with 

soil or standing water and product and hazard labels 

are not exposed to weathering. 

g) Rehabilitation of upland sites following disturbance 

would use the plant species listed in Table 3 for 

seeding. The species used for rehabilitation would 

vary depending on the adjacent habitat conditions, 

site potential, soils, and precipitation. Species not in 

the following list could be added if site conditions 

warrant, species availability changes or if there are 

large acreages are involved. 

h) All permanent structures will be painted the neutral 

color of Sand Beige (5Y 6/3), Desert Brown (10YR 

6/3), Carlsbad Canyon (2.5Y 6/2) or Slate Gray (5Y 

6/1) as displayed in the Standard Environmental 

Color chart (available at the BLM office) or other 

acceptable color approved by the authorized officer 

to blend in with the surrounding landscape. 

i) If the well is a dry hole, Operator will be required to 

fence the entire disturbed area of the location to 

allow the seedlings and vegetation to re-establish. 

This fencing must be stock tight and must remain in 

place until the BLM requests otherwise. 

j) The Operator will be responsible for control of 

noxious weeds occurring as a result of lease 

operations. The Surface Management Agency will 

be responsible for approval of weed control 

programs. 

k) Prior to the use of herbicides on public land, the 

applicant will have to obtain from the BLM 

authorized officer written approval of a plan 

showing the type and quantity of material to be 

used, weed(s) to be controlled, method of 

application, location of storage and disposal of 

containers and any other pertinent information 

deemed necessary by the authorized officer. 

Operators must monitor disturbed areas annually 

from June through August for the presence of 

noxious weeds. Monitoring must begin prior to 

disturbance. 

l) Within the Distribution Zone of grizzly bears, food 

storage regulations will be followed to minimize 

bear-human conflicts. Proper food storage is 

essential to successful human-bear management. 

“Food” includes actual food, trash, recyclables, 

toiletries, cosmetics, first aid kits, pet food, 

sunscreen, baby wipes, scented tissue, beverage 

cans and bottles, canned food, mosquito repellant, 

tobacco products, and any related items with a 

scent. All food items, garbage, beverages, coolers, 

stoves, grills, cooking utensils, food containers, and 

pet food not in immediate use (day or night) must 

stored in Bear Resistant Containers (BRC), stored in 

a closed vehicle constructed of solid, nonpliable 

material or be hung from food poles where provided 

or limbs of trees. Food items must be hung 10 feet 

clear of the ground at all points and 4 feet 

horizontally from any supporting tree or pole. 

Camps and job sites must be clean at all times. No 

garbage will be burned or buried. All garbage will 

be removed from the site.

notify the authorized officer by letter or sundry 

notice, Form 3160-5, or orally to be followed by a 

letter or sundry notice, of the date on which such 

production has begun or resumed. 

Hazardous Materials 

a) Operators and their contractors are to ensure all 

production, use, storage, transport, and disposal of 

hazardous materials resulting from the proposed 

project is in accordance with all applicable Federal, 

State and local laws, regulations and guidelines, 

existing or hereafter enacted or promulgated that 

effect the management of hazardous material, as 

defined in this paragraph. Hazardous material 

means any substance, pollutant, or contaminant 

listed as a hazardous substance under the 

Comprehensive Environmental Response, 

Compensation and Liability Act (CERCLA) of 

1980, as amended, 42 USC 9601 et seq., and its 

regulations (found at 40 CFR 302). The definition 

of hazardous substances under CERCLA includes 

“hazardous waste” defined in the Resource 

Conservation and Recovery Act (RCRA) of 1976, 

as amended, 42 USC 6901 et seq., and its 

regulations. The term also includes any extremely 

hazardous substances defined by 40 CFR 355 and 

any nuclear or byproduct material defined by the 

Atomic Energy Act of 1954, as amended, 42 USC 

2011 ET seq. The term does not include petroleum, 

including crude oil or any fraction thereof not 

otherwise listed or designated as a hazardous 

substance under CERCLA section 101 (14), 42 USC 

9601 (14), or natural gas. 

b) Only drilling mud, drilling fluids, cuttings, native 

soils, cementing materials and/or approved pit 

solidifying materials will be placed in the reserve or 

working pits. 

c) Nonexempt wastes will not be mixed with exempt 

wastes. 

Environmental Obligations and Disposal 

of Produced Water 

a) The Operator is required to take all necessary steps 

to prevent any death of a migratory bird in pits or 

open vessels associated with the drilling, testing, 

completion, or production of this well. The death of 

any migratory bird found in such a pit or open 

vessel is a violation of the Migratory Bird Treaty 

Act and is considered a criminal act. Any deaths of 

migratory birds attributable to pits or open vessels 

associated with drilling, testing, completing, or 

production operations must be reported to this office 

Butte Draft RMP/EIS 895 
Appendix L 

and the United States Fish and Wildlife Service 

within 24 hours. 

b) The BLM may require that the pit be designed or 

the open vessel be covered to deter the entry of 

birds in any facility associated with drilling, testing, 

completing, or production of this well. Fencing, 

screening, and netting of pits may be required as a 

means to deter bird entry. These conditions would 

most likely be imposed to prevent the entry of 

migratory birds if oil is left in pits or open vessels 

after the cessation of drilling or completion 

operations, if water disposal pits consistently 

receive oil, or if pits or open vessels are used 

repeatedly for emergency situations which result in 

the accumulation of oil. 

c) Voluntary pit fencing, screening, and netting, or 

sealing vessels is encouraged thus avoiding 

potential instances that may result in the death of a 

migratory bird. 

d) With BLM approval, water produced from newly 

completed wells may be temporarily disposed of 

into unlined pits for up to 90 days. During this 

initial period, application for the permanent disposal 

method must be made in accordance with Onshore 

Order No. 7. 

Paleontological/Cultural Stipulations 

Paleontological and archaeological field checks by BLM 

personnel or other authorized personnel will occur prior 

to disturbance as deemed appropriate by the BLM. A 

BLM-approved archaeologist or paleontologist will 

conduct monitoring during surface-disturbing activities. 

Paleontological or cultural resource sites will be avoided 

or mitigated as necessary prior to disturbance. Any 

cultural or paleontological resource discovered by an 

operator or any person working on his/her behalf will be 

reported immediately to the BLM, and all operations that 

may further disturb such resources will be suspended 

until written authorization to proceed is issued by the 

BLM authorizing officer. An evaluation of the discovery 

will be made by the BLM to determine appropriate 

actions to prevent the loss of significant resources. 

CONSTRUCTION 

Construction of the access road and the well site is 

necessary before drilling operations begin. The extent of 

surface disturbance necessary for construction depends 

on the terrain, depth of the well, drill rig size, circulating 

system, and safety standards. 

The depth of the drill test determines the size of drill rig 

needed, and therefore, the size of the work area 

necessary, the need for all-weather roads, water 

requirements, and other needs. The terrain influences the 

construction problems and the amount of surface area to 

be disturbed. Reserve pit size may vary because of well 

depth, drill rig size, or circulating system. 

Access roads to well sites in the planning area usually 

consist of running surfaces 14 to 24 feet wide that are 

ditched on one or both sides. Many of the roads 

constructed will follow existing roads or trails. New 

roads might be necessary because existing roads are not 

at an acceptable standard. For example, a road may be 

too steep so that realignment is necessary. 

Roads can be permanent or temporary, depending on the 

success of the well. The initial construction can be for a 

temporary road; however, it is designed so that it can 

become permanent if the well produces. Not all 

temporary roads constructed are immediately 

rehabilitated when the drilling stops. A temporary road 

is often used as access to other drill sites. The main 

roads and temporary roads require graveling to be 

maintained as all-weather roads. This is especially 

important in the spring. Access roads may be required to 

cross public lands to a well site located on private or 

state lands. The portion of the access road on public land 

would require a BLM right-of-way. 

The amount of level surface required for safely 

assembling and operating a drilling rig varies with the 

type of rig, but averages 300 feet by 400 feet. 

Approximately 3-1/2 acres would be impacted by well 

site construction. The area is cleared of large vegetation, 

boulders, or debris. Then the topsoil is removed and 

saved for reclamation. A level area is then constructed 

for the well site, which includes the reserve pit. 

Bulldozers and motor scrapers are typically used to 

construct the well pad. The well pad is flat (to 

accommodate the drill rig and support equipment) and 

large enough to store all the equipment and supplies 

without restricting safe work areas. The drill rig must be 

placed on “cut” material rather than on “fill” material to 

provide a stable foundation for the rig. The degree of 

cutting and filling depends on terrain; that is, the flatter 

the site, the less dirt work is required. 

Hillside locations are common, and the amount of dirt 

work varies with the steepness. A typical well pad will 

require a cut 10 feet deep against the hill and a fill 8 feet 

high on the outside. It is normal to have more cut than 

fill to allow for compaction, and any excess material is 

then stockpiled. Eventually, when the well is plugged 

and abandoned, excavated material is put back in its 

original place. 

Reserve pits are normally constructed on the well pad. 

Usually the reserve pit is excavated in “cut” material on 

the well pad. The reserve pit is designed to hold water, 

drill cuttings, and used drilling fluids. Generally, reserve 

pits are rectangular in shape and 8 to 12 feet deep, 

however, the size and number of pits depends on the 

depth of the well, circulating system and anticipated 

down hole problems, such as excess water flows. The 

reserve pit can be lined with a synthetic liner to contain 

pit contents and reduce pit seepage. Not all reserve pits 

are lined; however, BLM can require a synthetic liner 

896 Butte Draft RMP/EIS 
Fluid Minerals 

based upon factors such as soils, pit locations, ground 

water, and drilling mud constituents. The operator can 

elect to line the reserve pit without that requirement. Pits 

may be divided into compartments separated by berms 

for the proper management of derived waste (e.g., drill 

cuttings, mud, water flows). 

An adequate supply of water is required for drilling 

operations and other uses. During drilling operations, 

water is continually transported to the rig location. 

Approximately 1,680,000 gallons of water are required 

to drill an oil or gas well to the depth of 9,000 feet. The 

sources of water can be a water well at the drill site or 

remote sources such as streams, ponds, or wells. The 

water is transported to the site by truck or pipeline. 

Pipelines are normally small diameter surface lines. The 

operator must file for and obtain all necessary permits 

for water from the state of Montana. On public lands, an 

operator must have the BLM’s permission before surface 

water can be used. 

DRILLING OPERATIONS 

Starting to drill is called “spudding in” the well. Initially, 

drilling proceeds rapidly due to the presence of 

unconsolidated or shallow, poorly consolidated rock 

formations. Drilling is accomplished by rotating special 

bits under pressure at the end of drill pipe (string) 

extended down the hole as it advances. While drilling, 

the rig derrick and associated hoisting equipment bear 

most of the drill pipe (string) weight. The weight on the 

bit is generally a small fraction of the total drill string 

weight. The combination of rotary motion and weight on 

the bit causes rock to be chipped away at the bottom of 

the hole. 

Drilling fluid or mud is circulated through the drill pipe 

to the bottom of the hole, through the bit, up the bore of 

the well, and finally to the surface. When the mud 

emerges from the hole, it goes through equipment used 

to screen and remove rock chips and sand-size solids. 

When the solids have been removed, the mud is placed 

into holding tanks and from the tanks it is pumped back 

into the well. The mud is maintained at a specific weight 

and viscosity to cool the bit, seal off any porous zones 

(protect aquifers or prevent damage to producing zone 

productivity), subsurface pressure control, lubrication of 

the drill string, clean the bottom of the hole, and bring 

the rock chips to the surface. 

There are three common types of drilling fluids: waterbased, oil-based, and synthetic. Water-based muds are 

the most common and are largely made up of water and 

bentonite, clay that has special properties used to 

maintain proper viscosity and other properties over a 

wide range of drilling conditions. Oil-based mud is used 

for subsurface conditions where water may react with 

shale and cause caving and sloughing of the sides of the 

well bore. Synthetic drilling fluids are used for special 

conditions and have become more common in recent 

years. They are composed of organic polymers or other 

chemicals and are often designed to be environmentally 

benign. Additives are used to maintain the drilling mud 

properties for specific conditions that may be 

encountered during drilling. 

As drilling progresses for a vertical well, pipe or casing 

is placed as a liner in the hole. Casing consists of steel 

pipe that is placed into the hole to prevent the collapse of 

the hole, to protect aquifers, and to isolate producing 

zones from other formations. Several strings of casing, 

that have different purposes, may be placed into the 

well. The first string of pipe is the conductor pipe, which 

stabilizes the hole near the surface. The second string of 

pipe placed in the hole is for surface casing, which is set 

deep enough to reach a competent rock below the 

deepest usable freshwater aquifer. 

The surface casing is set and cemented in the hole by 

pumping cement between the casing and the well bore 

wall. Surface casing acts as a safety device to protect 

freshwater zones from drilling fluid contamination. To 

prevent the well from “blowing-out” in the event the 

drill bit hits a high-pressure zone, blowout preventers are 

mounted on top of the surface casing. If high-pressure 

zones are encountered that cannot be controlled with 

weighting using mud additives (drilling fluids are the 

first line of defense against a blowout), the blowout 

preventers can be closed through a system of 

hydraulically activated valves and manifolds to 

effectively seal the well and prevent the uncontrolled 

flow of fluids. 

After the surface casing is set, a smaller drill bit that fits 

inside the surface casing is installed and drilling 

resumes. Depending on well conditions, additional 

strings of casing called intermediate casing may be 

installed and cemented into place. Conditions resulting 

in the need for intermediate casing include freshwater 

zones and sloughing formation zones. Casing prevents 

the flow of freshwater into the wellbore, and conversely 

prevents drilling fluids from infiltrating porous 

formations with low internal pressures. Casing also 

prevents mixing of waters from different formations 

(interformational mixing) where water within the 

formations is of differing quality. 

All cementing operation plans are reviewed to assure 

cement is placed at the appropriate depths and a 

sufficient quantity is utilized to effectively seal all 

freshwater-bearing formations from contamination by 

interformational mixing or migration of fluids. 

Drilling operations are continuous, 24 hours a day, 7 

days a week. There are three 8-hour or two 12- hour 

shifts a day. Pickups or cars are used for workers' 

transportation to and from the location. 

If no oil or gas is encountered, the well is called a “dry 

hole” and it is plugged with cement and abandoned in 

accordance with state and federal requirements. The drill 

site and access roads are rehabilitated according to 

Butte Draft RMP/EIS 897 
Appendix L 

stipulations and conditions attached to the approved 

APD and the drilling equipment is moved to another 

location. 

If the well is a producer, casing is set and cemented in 

place. 

Directional drilling may be used where the drill site 

cannot be located directly over the drilling target. There 

are limits to both the degree that the well bore can be 

deviated from the vertical and the horizontal distance the 

well can be drilled away from the well site. 

Horizontal wells are drilled similarly to directional 

wells, except that the bottomhole location of the well is 

not a single point, but rather a lateral horizontal section. 

They are drilled to increase the recovery oil and gas 

reserves from vertically fractured reservoirs, or 

reservoirs with directional permeability. 

PRODUCTION AND 

DEVELOPMENT 

Production 

Production begins when a well yields oil or gas in 

commercial quantities. If formation pressure is sufficient 

to raise oil to the surface, the well is completed as a 

flowing well. A pumping unit is installed if the 

formation pressure is not sufficient to bring the oil to the 

surface. 

When the well is completed as a free-flowing well, an 

assembly of valves and special connections known as a 

“Christmas tree” (so called because of its many branchlike fittings) is installed on top of the casing to regulate 

the flow of the well. Later, when the natural pressure 

declines, the Christmas tree can give way to a simple 

wellhead arrangement of valves and a pumping unit to 

lift the oil artificially. Many pumping units are “beam” 

style pumps that are powered by electric motors or 

gasoline engines. Most gas wells produce by natural 

flow and do not require pumping. Surface facilities at a 

flowing well are usually in a small area containing a gas 

well Christmas tree, a dehydrator, a produced water pit, 

and a meter house. Separators, condensate tanks, and 

compressors may be included. Some gas wells require 

continuous water pumping as water entering the well 

chokes off the gas flow. 

Development 

New field development may be analyzed under NEPA 

by means of an environmental assessment (EA) or 

environmental impact statement (EIS) usually after the 

second or third confirmation well is drilled. The operator 

should then have an idea of the extent of drilling and 

disturbance required to extract and produce the oil and 

gas. When an oil or gas discovery is made, a well 

spacing pattern must be established before development 

drilling begins. 

Development can take years and include from one or 

two wells to more than a hundred wells per field. 

However, the reasonably foreseeable development 

scenario for this planning document should only 

forecasts two additional wells per field. Roads to 

producing wells are upgraded to all-weather roads as 

necessary. Pipelines, electrical transmission lines, 

separators, dehydrators, sump pits, and compressor 

stations soon follow. Sometimes oil and gas processing 

facilities are built in or adjacent to the field. 

Further Seismic Testing 

More detailed seismic work can be done to achieve 

better definition of the petroleum reservoir. Diagonal 

seismic lines can be required to tie the previous seismic 

work to the discovery well. The discovery well can be 

used to conduct studies to correct the previous seismic 

work and provide more accurate subsurface data. 

Spacing Requirements 

A well spacing pattern must be established before 

development drilling begins. Information considered in 

establishment of a spacing pattern includes data from the 

discovery well on porosity, permeability, pressure, 

composition, and depth of formations in the reservoir; 

well production rates and type (predominantly oil or 

gas); and the economic effect of the proposed spacing on 

recovery. The state of Montana establishes well spacing 

patterns for both exploratory and development wells 

which the BLM generally adopts. The state specifies the 

minimum distance from lease lines or government 

survey lines for the bottom hole location of the well bore 

depending upon depth of the well. The spacing 

regulations determine the acres assigned to each well. 

Spacing unit size is established to provide for the most 

efficient and economic recovery of oil or gas from a 

reservoir. Normal well spacing ranges from 40 acres to 

640 acres (Figures A-2 and A-3). Wells deeper than 

11,000 feet can be no closer than 1,650 feet to other 

producing wells below 11,000 feet. Only one producing 

well per formation is allowed in each 40, 80, 160, 320, 

and 640-acre unit. 

Drilling of Development Wells 

The procedures used in drilling development wells are 

the same as those used for wildcat wells, but usually 

with less subsurface sampling, testing, and evaluation. 

The rate at which development wells are drilled in a 

field depends on factors such as whether the field is 

developed on a lease basis or unitized basis, the 

probability of profitable production, the availability of 

drilling equipment, lease requirements, and the degree to 

which limits of the field are known. Some fields go 

through several development phases, the first resulting 

from the original discovery and others from later 

discovery. A field can be considered fully developed and 

produce for several years, and then a well may be drilled 

to a deeper or shallower pay zone. Discovery of a new 

898 Butte Draft RMP/EIS 
Fluid Minerals 

pay zone in an existing field is a “pool” discovery (as 

distinguished from a new field discovery). A pool 

discovery may lead to the drilling of additional wells, 

often from the same drilling pad as existing wells. 

Inspections 

Geophysical operations and lease operations are 

inspected to determine compliance with approved 

permits, to resolve conflicts or correct problems and to 

determine effectiveness and need of lease stipulations. 

All inspections are documented. Operators are required 

to correct problems or violations. 

Surface Requirements 

Field development activities that cause surface 

disturbance include access roads, well sites, production 

facility sites, flow line and utility line routes and waste 

disposal sites. Surface uses in a gas field will be less 

than in an oil field, because gas wells are usually drilled 

on larger spacing units. The spacing pattern of 640 acres 

per well, which is common in gas fields, will require 

only one well per section and might require only 1/2 

mile of access roads and pipelines. Production facilities 

include separation and storage equipment. Separation 

equipment is required when production includes a 

combination of oil, gas, or water and storage equipment 

is required for holding liquids prior to sales. 

Flow Lines 

Oil and gas are transferred from the well to storage 

facilities through small diameter (<6 inches) flow lines. 

Flow lines can be on the surface, buried or elevated. 

Produced water, gas, or polymerized liquid is transferred 

from storage facilities to injection wells for secondary 

recovery. 

Separating, Treating, and Storage 

Any water or gas associated with produced oil is 

separated from the oil before it is placed in storage 

tanks. The treating facilities are located at a storage tank 

battery. Low-pressure petroleum that must be pumped 

from the well is treated in a single separation. Highpressure, flowing petroleum can require several stages or 

separation, with a pressure reduction accompanying each 

stage. 

Produced gas is sold when there is sufficient volume, 

necessary transportation, a market, and it is economical. 

Generally, if the volume of produced gas is too low for 

sales, it is used as fuel for well pump engines and 

heating fuel for the treaters. If the volume of produced 

gas exceeds fuel requirements on the lease but gas sales 

are not possible, the gas can be flared or vented into the 

atmosphere when authorized by permit in accordance 

with state and federal regulations. When water is 

produced with the hydrocarbons, it is separated before 

the gas is removed. In primary operations, where natural 

pressures or gravity causes the petroleum in the reservoir 

to flow to the wellbores, the degree of mixing is high 

enough to require chemical and heat treatment to 

separate the oil and water. In secondary production, 

where water injection or other methods are used to force 

additional petroleum to the wellbore, the oil and water 

often are not highly emulsified. In this case, the oil and 

water can be separated by gravity in a tall settling tank. 

Produced water can be disposed of by injection into the 

subsurface, surface evaporation or beneficial purposes 

such as water for livestock or irrigation. 

Produced water from oil and gas operations is normally 

disposed of by subsurface injection or in surface pits. 

Regardless of the method of disposal, it must be 

acceptable to the BLM, in accordance with the 

requirements of Onshore Oil and Gas Order No. 7, titled 

“Disposal of Produced Water.” Disposal of produced 

water by injection wells requires permits from the 

Montana Board of Oil and Gas Conservation. When 

produced water is disposed underground, it is introduced 

or injected under pressure into a subsurface horizon 

containing water of equal or poorer quality. Produced 

water may be injected into the producing zone from 

which it originated to stimulate oil production. Dry holes 

or depleted wells are commonly converted for saltwater 

disposal and occasionally new wells are drilled for this 

purpose. The law and regulations require that all 

injection wells be permitted under the Underground 

Injection Control program. 

Under the Underground Injection Control approval 

process, the disposal well must be pressure tested to 

ensure the integrity of the casing. The disposal zone 

must also be isolated by use of tubing and mechanical 

plug called a packer. The packer seals off the inside of 

the casing and only allows the injected water to enter the 

disposal zone. The tubing and packer are also pressure 

tested to ensure their integrity. These pressure tests 

confirm isolation of the disposal zone from possible 

usable water zones. The oil is transported to storage 

tanks through flow lines after separation from any water 

or gas. Storage tanks are usually located on the lease 

either at the producing well or at a central production 

facility. The number and size of tanks are dependent 

upon the type and amount of production on the lease. 

ABANDONMENT 

When drilling wells are unsuccessful or production wells 

are no longer useful, the well is plugged, equipment is 

removed from the well site or production facility site, 

and the site is abandoned. The well bore is secured by 

placing cement plugs to isolate hydrocarbon-producing 

formations from contaminating other mineral or water 

bearing formations. The site and roads are then restored 

as near as possible to original contours. Topsoil is 

replaced and the recontoured areas are seeded. 

Reclamation of access roads and well sites on privately 

owned surface is completed according to the surface 

owner’s requirements. 

Butte Draft RMP/EIS 899 
Appendix L 

Rehabilitation requirements generally are made a part of 

the Application for Permit to Drill. Upon completion of 

abandonment and rehabilitation operations, the lessee or 

operator notifies the Great Falls Oil and Gas Field 

Station that the location is ready for inspection. Final 

abandonment will not be approved until the required 

surface reclamation work has been completed to the 

satisfaction of the BLM or surface owner. The period of 

bond liability for the well site is terminated after 

approval of final abandonment. Reclamation of the 

reserve pit is part of the well site reclamation process. 

Reserve pit reclamation includes removal of fluids to a 

disposal well or commercial pit and burial of solids in 

the pit. Solids should not be buried until dry and then 

covered with a minimum of 6 feet of native soil. Any pit 

liner may be buried in place. Methods such as 

solidification or dewatering may be used to help dry the 

solids.

SPECIAL PROCEDURES 

UNIT AND COMMUNITIZATION 

AGREEMENTS 

Unit and communitization agreements can be formed in 

the interest of conservation and to allow for the orderly 

development of oil and gas reserves. A unit agreement 

provides for the recovery of oil and gas from the lands as 

a single consolidated entity without regard to separate 

lease ownerships. An exploratory unit is used for the 

discovery and development of the field in an orderly and 

efficient manner. Paying and nonpaying well 

determinations are made for each well drilled. If the well 

is nonpaying as defined by the agreement, the 

production is allocated on a lease basis. If the well is a 

paying unit well, a participating area is formed and the 

production is allocated to all interest owners in the 

participating area based on surface area. A secondary 

unit is formed after the field has been defined and 

enhanced recovery techniques are being utilized. 

Secondary recovery techniques include water injection, 

natural gas injection, or carbon dioxide injection. 

Injection is initiated to maintain the reservoir pressure to 

maintain oil production. The agreement provides for the 

allocation of production among all the interest owners. 

A communitization agreement combines two or more 

leases (federal, state, or fee) that otherwise could not be 

independently developed in conformity with established 

well spacing patterns. The leases within the spacing unit 

share in the costs and benefits of the well drilled in the 

spacing unit. Therefore, unit and communitization 

agreements can lessen the amount of damage to the 

environment and 

unnecessary wells,

SPLIT ESTATE 

Part of the area included in the planning area contains 

lands known as split estate lands. These are lands where 

the surface ownership is different from the mineral 

ownership. Management of federal oil and gas resources 

on these lands is somewhat different from management 

on lands where both surface and mineral ownership is 

federal. On split estate lands where the surface 

ownership is private, the BLM places necessary 

restrictions and requirements on its leases and permit 

approvals and works in cooperation with the surface 

owner. BLM has established policies for the 

management of federal oil and gas resources in 

accordance with federal laws and regulations. 

The BLM does not have the legal authority to regulate 

how private surface is managed. BLM does have the 

statutory authority to require measures by lessees to 

avoid or minimize adverse impacts that may result from 

federally authorized mineral lease activities. These 

measures, in the form of lease stipulations or permit 

conditions of approval, are intended to protect or 

preserve the privately owned resources and prevent 

adverse impacts to adjoining lands, not to dictate 

management to the surface owner. The term split estate 

can also refer to lands where the surface ownership is 

federal and the mineral ownership is private. In this 

situation, BLM is the surface owner, and works in 

cooperation with the proponent and the state regulatory 

agency that approves private mineral applications. BLM 

has responsibilities in this situation under the previously 

mentioned statutes; however, BLM does not have the 

authority to approve or disapprove the mineral owner’s 

actions. The mineral estate owner usually has the right to 

enter the land and use the surface that is necessary and 

reasonable for mineral development through either a 

reserved or an outstanding right contained in the deed.
