(a) Each individual tract committed to the unit agreement meets its full performance obligation if one or more tracts in the unit meets the development or production requirements;

(b) Production from a well that meets the productivity criteria (see § 3137.82 of this subpart) under the unit agreement extends the term of all NPR-A leases committed to the unit agreement as provided in § 3137.111 of this subpart;

(c) You may drill within the unit without regard to certain lease restrictions, such as lease boundaries within the unit and spacing offsets; and

(d) You may consolidate operations and permitting and reporting requirements.

If the BLM administers a unit containing tracts where the mineral estate is owned by a regional corporation or the State of Alaska, or if a proposed unit contains tracts where the mineral estate is owned by a regional corporation or the State of Alaska, the BLM will consult with and provide opportunities for participation in negotiations with respect to the creation or expansion of the unit by—

(a) The regional corporation, if the unit acreage contains the regional corporation's mineral estate; or

(b) The State of Alaska, if the unit acreage contains the state's mineral estate.

As used in this subpart—

Actual drilling means operations you conduct that are similar to those that a person seriously looking for oil or gas could be expected to conduct in that particular area, given the existing knowledge of geologic and other pertinent facts about the area to be drilled. The term includes the testing, completing, or equipping of the drill hole (casing, tubing, packers, pumps, etc.) so that it is capable of producing oil or gas. Actual drilling operations do not include preparatory or preliminary work such as grading roads and well sites, or moving equipment onto the lease.

Actual production means oil or gas flowing from the wellbore into treatment or sales facilities.

Actual reworking operations means reasonably continuous well-bore operations such as fracturing, acidizing, and tubing repair.

Committed tract means—

(1) A Federal lease where all record title holders and all operating rights owners have agreed to the terms and conditions of a unit agreement, committed their interest to the unit; or

(2) A State lease or private parcel of land where all oil and gas lessees and all operating rights owners or the owners of unleased minerals have agreed to the terms and conditions of a unit agreement.

Constructive drilling means those activities that are necessary to prepare for actual drilling that occur after BLM approves an application to drill, but before you actually drill the well. These include, but are not limited to, activities such as road and well pad construction, and drilling rig and equipment set-up.

Constructive reworking operations means activities that are necessary to prepare for well-bore operations. These may include rig and equipment set-up and pit construction.

Continuing development obligations means a program of development or operations you conduct that, after you complete initial obligations defined in a unit agreement—

(1) Meets or exceeds the rate of non-unit operations in the vicinity of the unit; and

(2) Represents an investment proportionate to the size of the area covered by the unit agreement.

Drainage means the migration of hydrocarbons, inert gases (other than helium), or associated resources caused by production from other wells.

NPR-A lease means any oil and gas lease within the boundaries of the NPR-A, issued and administered by the United States under the Naval Petroleum Reserves Production Act of 1976, as amended (42 U.S.C. 6501-6508), that authorizes exploration for and removal of oil and gas.

Operating rights (working interest) means any interest you hold that allows you to explore for, develop, and produce oil and gas.

Participating area means those committed tracts or portions of those committed tracts within the unit area that are proven to be productive by a well meeting the productivity criteria specified in the unit agreement.

Primary target means the principal geologic formation that you intend to develop and produce.

Producible interval means any pool, deposit, zone, or portion thereof capable of producing oil or gas.

Record title means legal ownership of an oil and gas lease recorded in BLM's records.

Tract means land that may be included in an NPR-A oil and gas unit agreement and that may or may not be in a Federal lease.

Unit agreement means a BLM-approved agreement to cooperate in exploring, developing, operating and sharing in production of all or part of an oil or gas pool, field or like area, including at least one NPR-A lease, without regard to lease boundaries and ownership.

Unit area means all tracts committed to a BLM-approved unit. Tracts not committed to the unit, even though they may be within the external unit boundary, are not part of the unit area.

Unit operations are all activities associated with exploration, development drilling, and production operations the unit operator(s) conducts on committed tracts.

If the Federal lands constitute less than 10 percent of the lands in the proposed unit area—

(a) You may use a unit agreement approved by the State and/or a native corporation;

(b) BLM will authorize commitment of the Federal lands to the unit if it determines that the unit agreement protects the public interest; or

(c) As unit operator you may ask BLM to approve and administer the unit. If BLM agrees to approve and administer the unit, you must follow, and BLM will administer, the regulations in this subpart and 43 CFR part 3160.

There is no standard unit agreement form. BLM will accept any unit agreement format if it protects the public interest and includes the mandatory terms required in § 3137.21 of this subpart.

(a) Your NPR-A unit agreement must include—

(1) A description of the unit area and any geologic and engineering factors upon which you are basing the area;

(g) A discussion of the proposed methodology for allocating production among the committed tracts. If the unit includes non-Federal oil and gas mineral estate, you must explain how the methodology takes into account reservoir heterogeneity and area variation in reservoir producibility; and

(h) Other documentation that the BLM may request. The BLM may require additional copies of maps, plats, and other similar exhibits.

(i) The processing fee found in the fee schedule in § 3000.120 of this chapter.

BLM will reject a unit agreement application—

(a) That does not address all mandatory terms, including those required under § 3137.21(b) of this subpart;

(b) If the unit operator—

(1) Has an unsatisfactory record of complying with applicable laws, regulations, the terms of any lease or permit, or the requirements of any notice or order; or

(2) Is not qualified to operate within NPR-A under applicable laws and regulations;

(c) That does not conserve natural resources;

(e) That does not comply with any special conditions in effect for any part of the NPR-A that the unit or any lease subject to the unit would affect; or

(f) That does not comply with the requirements of this subpart.

BLM will notify the unit operator in writing when it approves or disapproves the proposed unit agreement. The unit operator must notify, in writing, all parties to the unit agreement within 30 calendar days after receiving BLM's notice of approval or disapproval.

The unit agreement is effective on the date BLM approves it.

No subsequent contract or obligation—

(a) Modifies the terms or conditions of the unit agreement; or

(b) Relieves the unit operator of any right or obligation under the unit agreement.

A unit agreement includes all oil and gas resources of committed tracts unless BLM approves unit agreement terms to the contrary pursuant to § 3137.50 of this subpart.

Your unit agreement must define—

(a) The number of wells you anticipate will be necessary to assess the reservoir adequately;

(b) A primary target for each well;

(c) A schedule for starting and completing drilling operations for each well; and

(d) The time between starting operations on a well to the start of operations on the next well.

A unit agreement must provide for submission of supplemental or additional plans of development which obligate the operator to a program of exploration and development (see § 3137.71 of this subpart) that, after completion of the initial obligations —

(a) Meets or exceeds the rate of non-unit operations in the vicinity of the unit; and

(b) Represents an investment proportionate to the size of the area covered by the unit agreement.

BLM may approve the following optional terms for a unit agreement if they promote additional development or enhanced production potential—

(a) Limiting the unit agreement to certain formations and their intervals;

(b) Multiple unit operators (see § 3137.51 of this subpart);

(c) Allowing modification of the unit agreement terms if less than 100 percent of the parties to the unit agreement (see § 3137.52 of this subpart) agree to the modification; or

(d) Other terms that BLM determines will promote the greatest economic recovery of oil and gas consistent with applicable law.

BLM permits multiple unit operators only if the unit agreement defines—

(a) The conditions under which additional unit operators are acceptable;

(b) The responsibilities of the different operators, including obtaining BLM approvals, reporting, paying Federal royalties and conducting operations;

(c) Which unit operators are obligated to ensure bond coverage for each NPR-A lease in the unit;

(d) The consequences if one or more unit operators defaults. For example, if an operator defaults, the unit agreement would list which unit operators would conduct that operator's operations and ensure bonding of those operations; and

(e) Which unit operator is responsible for unit obligations not specifically assigned in the unit agreement.

(a) You may modify a unit agreement if—

(1) All current parties to the unit agreement agree to the modification; or

(2) You meet the requirements of the modification provision in the unit agreement. The modification provision must identify which parties, and what percentage of those parties, must consent to each type of modification.

(b) You must submit to BLM an application for modification. The application must include the following—

(1) The operator must certify that the necessary parties have agreed to the modification; and

(2) If the unit agreement modification alters the current allocation schedule, you must submit to BLM both a—

(i) Description of the new allocation methodology; and

(ii) New allocation schedule.

(c) A modification is not effective unless BLM approves it. After BLM approves the modification, it is effective retroactively to the date you filed a complete application for modification. However, BLM may approve a different effective date if you request it and provide acceptable justification.

(d) BLM will reject modifications that do not comply with BLM regulations or applicable law.

As the unit operator—

(a) You must comply with the terms and conditions of the unit agreement, Federal laws and regulations, lease terms and stipulations, and BLM notices and orders;

(b) You must provide to BLM evidence of acceptable bonding. Acceptable bonding means a bond in an amount which is no less than the sum of the individual Federal bonding requirements for each of the NPR-A leases committed to the unit. You may also meet this requirement if you add the unit operator as a principal to lease bonds to reach the required amount; and

(c) The bond must be payable to the Secretary of the Interior.

(a) To change unit operators, the new unit operator must submit to the BLM:

(1) Statements that:

(i) The new operator accepts unit obligations; and

(ii) The percentage of required interest owners consented to a change of unit operator;

(2) Evidence of acceptable bonding (see § 3137.60(b)); and

(3) The processing fee found in the fee schedule in § 3000.120 of this chapter.

(b) The effective date of the change in unit operator is the date the BLM approves the new unit operator.

You are responsible for all duties and obligations of the unit agreement that accrued while you were unit operator up to the date BLM approves a new unit operator.

(a) After BLM approves the change in unit operator, you, as the new unit operator, assume full liability, jointly and severally with the record title and operating rights owners, except as otherwise provided in paragraph (c) of this section and to the extent permitted by law, for—

(1) Compliance with the terms and conditions of the unit agreement, Federal laws and regulations, lease terms and stipulations, and BLM notices and orders;

(2) Plugging unplugged wells and reclaiming unreclaimed facilities that were installed or used before the effective date of the change in unit operator (this liability is joint and several with the former unit operator); and

(3) Those liabilities accruing during the time you are unit operator.

(b) Your liability includes, but is not limited to—

(1) Rental and royalty payments;

(2) Protecting the unit from loss due to drainage as provided in § 3137.64 of this subpart;

(3) Well plugging and abandonment;

(4) Surface reclamation;

(5) All environmental remediation or restoration required by law, regulations, lease terms, or conditions of approval; and

(6) Other requirements related to unit operations.

(c) Your liability for royalty and other payments on the unit is limited by section 102(a) of the Federal Oil and Gas Royalty Management Act of 1982, as amended (30 U.S.C. 1712(a)).

You must prevent uncompensated drainage of oil and gas from unit land by wells on land not subject to the unit agreement. Permissible means of satisfying the obligation include—

(a) Drilling a protective well if it is economically feasible. For this subpart, economically feasible means producing a sufficient quantity of oil or gas from a protective well in the unit for a reasonable profit above the cost of drilling, completing and operating the protective well;

(b) Paying compensatory royalty;

(c) Forming other agreements, or modifying existing agreements, that allow the tracts committed to the unit agreement to share in production after the effective date of the new or modified agreement; or

(d) BLM may require additional measures to prevent uncompensated drainage.

(a) To meet initial development obligations by the time specified in your unit agreement you must—

(1) Drill the required test well(s) to the primary target;

(2) Drill at least one well that meets the productivity criteria (see § 3137.82 of this subpart); or

(3) Establish, to BLM's satisfaction, that further drilling to meet the productivity criteria is unwarranted or impracticable.

(b) You must certify to BLM that you met initial development obligations no later than 60 calendar days after meeting the obligations. BLM may require you to supply documentation that supports your certification.

(a) Once you meet initial development obligations, you must perform additional development. Work you did before meeting initial development obligations is not continuing development. Continuing development includes the following operations—

(1) Drilling, testing, or completing additional wells to the primary target or other unit formations;

(2) Drilling or completing additional wells that establish production of oil and gas;

(3) Recompleting wells or other operations that establish new unit production; or

(4) Drilling existing wells to a deeper target.

(b) No later than 90 calendar days after meeting initial development obligations, submit to BLM a plan that describes how you will meet continuing development obligations. You must submit to BLM updated continuing obligation plans as soon as you determine that, for whatever reason, the plan needs amending.

(1) If you have drilled a well that meets the productivity criteria, your plan must describe the activities to fully develop the oil and gas field.

(2) If you fulfilled your initial development obligations, but did not establish a well that meets the productivity criteria, your plan must describe the further actual or constructive drilling operations you will conduct.

(a) If reasons beyond your control prevent you from meeting the initial or a continuing development obligation by the time specified in the unit agreement, you may apply to BLM for an extension of time for meeting those obligations. You must submit the request for an extension of time before the date the obligation is due to be met. In the application-

(1) State the obligation for which you are requesting an extension;

(2) List the reasons beyond your control that prevent you from performing the obligation; and

(3) State when you expect the reasons beyond your control to terminate.

(b) BLM will grant an extension of time to meet initial or continuing development obligations if we determine that-

(1) The extension encourages the greatest ultimate recovery of oil or gas or it is in the interest of conservation; and

(2) The reasons beyond your control prevent you from performing the initial or a continuing development obligation.

(c) The extension of time for performing the initial or a continuing development obligation will continue for so long as the conditions giving rise to the extension continue to exist.

Within 30 calendar days after receiving your proposed plan, BLM will notify you in writing that we—

(a) Approved your plan;

(b) Rejected your plan and explain why. This will include an explanation of how you should correct the plan to come into compliance; or

(c) Have not acted on the plan, explaining the reasons and when you can expect a final response.

No later than 90 calendar days after BLM's approval of your plan submitted under 3137.71(b), you must certify to BLM that you started operations to fulfill your continuing development obligations. BLM may require you to—

(a) Supply documentation to support your certification; and

(b) Submit periodic reports that demonstrate continuing development.

You may perform additional development either within or outside a participating area, depending on the terms of the unit agreement.

(a) After you establish a participating area, if you do not meet a continuing development obligation and BLM has not granted you an extension of time to meet the obligation, the unit contracts. This means that—

(1) All areas within the unit that do not have participating areas established are eliminated from the unit. Any eliminated areas are subject to their original lease terms; and

(2) Only established participating areas, whether they are actually producing or not, remain in the unit.

(b) Units contract effective the first day of the month after the date on which the unit agreement required the continuing development obligations to begin.

(c) If you do not meet a continuing development obligation before you establish a participating area, the unit terminates (see § 3137.132 of this subpart).

(a) Participating areas are those committed tracts or portions of those committed tracts within the unit area that are proven to be productive by a well meeting the productivity criteria specified in the unit agreement.

(b) You must include a description of the anticipated participating area(s) size in the unit agreement for planning purposes to aid in the mitigation of reasonably foreseeable and significantly adverse effects on NPR-A surface resources. The unit agreement must define the proposed participating areas. Your proposed participating area may be limited to separate producible intervals or areas.

(c) At the time you meet the productivity criteria discussed in § 3137.82 of this subpart, you must delineate those participating areas.

(a) The function of a participating area is to allocate production to each committed tract within a participating area. The BLM will allocate production for royalty purposes to each committed tract within the participating area using the allocation methodology agreed to in the unit agreement (see § 3137.23(g) of this subpart).

(b) For exploratory and primary recovery operations, BLM will consider gas cycling and pressure maintenance wells when establishing participating area boundaries.

(c) For secondary and tertiary recovery operations, BLM will consider all wells that contribute to production when establishing participating area boundaries.

(a) Productivity criteria are characteristics of a unit well that warrant including a defined area surrounding the well in a participating area. The unit agreement must define these criteria for each separate producible interval. You must be able to determine whether you meet the criteria when the well is drilled and you complete well testing, after a reasonable period of time to analyze new data.

(b) To meet the productivity criteria, the well must indicate future production potential sufficient to pay for the costs of drilling, completing, and operating the well on a unit basis.

(c) BLM will consider wells that contribute to unit production (e.g., pressure maintenance, gas cycling) when setting the participating area boundaries as provided in § 3137.81(b) and (c) of this subpart.

The first well you drill meeting the productivity criteria after the unit agreement is formed establishes an initial participating area. When you establish an initial participating area, lands that contain previously existing wells in the unit meeting the productivity criteria (see § 3137.82 of this subpart), will—

(a) Be added to that initial participating area as a revision, if the well is completed in the same producible interval; or

(b) Become a separate participating area, if the well is completed in a different producible interval (see also § 3137.88 of this subpart for wells that do not meet the productivity criteria).

To establish a new participating area or modify an existing participating area, you must submit to BLM a—

(a) Statement that—

(1) The well meets the productivity criteria (see § 3137.82 of this subpart), necessary to establish a new participating area. You must submit information supporting your statement; or

(2) Explains the reasons for modifying an existing participating area. You must submit information supporting your explanation;

(b) Map showing the new or revised participating area and acreage; and

(c) Schedule that establishes the production allocation for each NPR-A lease or tract, and each record title holder and operating rights owner in the participating area. You must submit a separate allocation schedule for each participating area.

(a) The effective date of an initial participating area is the first day of the month in which you complete a well meeting the productivity criteria, but no earlier than the effective date of the unit.

(b) The effective date of a modified participating area or modified allocation schedule is the earlier of the first day of the month in which you file the proposal for a modification or such other effective date as may be provided for in the unit agreement and approved by the BLM, but no earlier than the effective date of the unit.

(a) If you obtain new information demonstrating that the participating area should be larger than BLM previously determined, within 60 calendar days of obtaining the information, you must—

(1) File a statement, map and revised production allocation schedule under § 3137.84 of this subpart requesting addition to the participating area of all committed tracts or portions of committed tracts in the unit area that meet the productivity criteria;

(2) If the proposed expanded participating area is outside the existing unit boundaries, invite all owners of oil and gas rights (leased or unleased) and lease interests (record title and operating rights) in such additional land to join the unit. If the owners of oil and gas rights in any tract of such land join the unit, you must submit to BLM—

(i) An application to enlarge the unit to include the expanded area;

(ii) A map showing the expanded area of the unit and the information with respect to each additional committed tract you proposed to add to the unit specified in § 3137.23(c) of this subpart; and

(iii) A revised allocation schedule; and

(3) If any additional committed tract or tracts are added to the unit under paragraph (a)(2) of this section, you must file a statement, map and revised production allocation schedule under § 3137.84 of this subpart requesting addition to the participating area of all such committed tracts or portions of such committed tracts in the unit area meeting the productivity criteria.

(b) If you obtain information demonstrating that the participating area should be smaller than previously determined, within 60 calendar days of obtaining the information, you must file a statement, map and revised production allocation schedule under § 3137.84 of this subpart requesting removal from the participating area of all land that does not meet the productivity criteria.

If there are unleased Federal tracts in a participating area, you must—

(a) Include the unleased Federal tracts in the participating area, even though BLM will not share in unit costs;

(b) Allocate production for royalty purposes as if the unleased Federal tracts were leased and committed to the unit agreement under § 3137.100 of this subpart;

(c) Admit Federal tracts leased after the effective date of the unit agreement into the unit agreement on the date the lease is effective; and

(d) Submit to BLM revised maps, a list of committed leases, and allocation schedules that reflect the commitment of the newly leased Federal tracts to the unit.

If a well outside any of the established participating area(s) does not meet the productivity criteria, all operations on that well are non-unit operations and we will not revise the participating area. You must notify BLM within 60 calendar days after you determine a well does not meet the productivity criteria. You must conduct non-unit operations under the terms of the underlying lease or other federally-approved cooperative oil and gas agreements.

(a) If a well that does not meet the productivity criteria was drilled before the unit was formed, the production is allocated on a lease or other federally-approved oil and gas agreement basis. You must pay and report the royalties from any such well either as specified in the underlying lease or other federally-approved oil and gas agreements.

(b) If you drilled a well after the unit was formed and the well is completed within an existing participating area, the production becomes a part of that participating area production even if it does not meet the productivity criteria. BLM may require the participating area to be revised under § 3137.84 of this subpart.

(c) If a well not meeting the productivity criteria is outside a participating area, the production is allocated as provided in paragraph (a) of this section.

(a) If a well not meeting the productivity criteria was drilled before the unit was formed and is not included in the participating area, the operator of the well at the time the unit was formed may continue as operator.

(b) As unit operator, you must continue to operate wells drilled after unit formation not meeting the productivity criteria unless BLM approves a change in the designation of operator for those wells.

If you, as the unit operator, complete sufficient work so that a well BLM previously determined to be a non-unit well now meets the productivity criteria, you must demonstrate this to BLM within 60 calendar days after you determine that the well meets the productivity criteria. You must then modify an existing participating area or establish a new participating area (see § 3137.84 of this subpart).

(a) After contraction under § 3137.76 of this subpart, a participating area terminates 60 calendar days after BLM notifies you that there is insufficient production to meet the operating costs of that production, unless you show that within 60 calendar days after BLM's notification—

(1) Your operations to restore or establish new production are in progress; and

(2) You are diligently pursuing oil or gas production.

(b) If you demonstrate to BLM that reasons beyond your control prevent you, despite reasonable diligence, from meeting the requirements in paragraphs (a)(1) and (a)(2) of this section within 60 calendar days after BLM notifies you that there is insufficient production to meet the operating costs of that production, BLM will extend the period of time to start those operations.

(a) When a participating area includes unleased Federal lands, you must allocate production as if the unleased Federal lands were leased and committed to the unit agreement (see §§ 3137.80 and 3137.81 of this subpart). The obligation to pay royalty for production attributable to unleased Federal lands accrues from the later of the date the—

(1) Committed leases in the participating area that includes unleased Federal lands receive a production allocation; or

(2) Previously leased tracts within the participating area become unleased.

(b) The royalty rate applicable to production allocated to unleased Federal lands is the greater of 12 1/2 percent or the highest royalty rate for any lease committed to the unit.

(c) The value of the production must be determined under the Minerals Management Service's oil and gas product value regulations at 30 CFR part 206.

A unit agreement does not modify Federal lease stipulations.

If the unit operator requests it, the BLM will extend the primary term of all NPR-A leases committed to a unit agreement or renew the leases committed to a unit agreement if any committed lease within the unit is extended or renewed under § 3135.1-5 or § 3135.1-6. If the BLM approves a lease renewal under § 3135.1-6(b), the BLM will require a renewal fee of $100 per acre for each lease in the unit that is renewed.

(a) If you demonstrate to BLM that reasons beyond your control prevent you, despite reasonable diligence, from starting actual or constructive drilling, reworking, or completing operations, BLM will extend all committed NPR-A leases as if you were performing constructive or actual drilling or reworking operations. You are limited to two extensions under this section.

(b) You must resume actual or constructive drilling or reworking operations when conditions permit. If you do not resume operations—

(1) BLM will cancel the extension; and

(2) The unit terminates (see § 3137.131 of this subpart).

As a transferee of an interest in an NPR-A lease that is included in a unit agreement, you are subject to the terms and conditions of the unit agreement.

BLM will approve the voluntary termination of the unit at any time—

(a) Before the unit operator discovers production sufficient to establish a participating area; and

(b) The unit operator submits to BLM certification that at least 75 percent of the operating rights owners in the unit agreement, on a surface acreage basis, agree to the termination.

If the unit terminated before the unit operator met the initial development obligations, BLM's approval of the unit agreement is revoked. You, as lessee, forfeit all further benefits, including extensions and suspensions, granted any NPR-A lease because of having been committed to the unit. Any lease that the BLM extended because of being committed to the unit would expire unless it had been granted an extension or renewal under § 3135.1-5 or § 3135.1-6.

If you do not meet a continuing development obligation before you establish any participating area, the unit terminates automatically. Termination is effective the day after you did not meet a continuing development obligation.

After participating areas are established, the unit terminates when the last participating area of the unit terminates (see § 3137.92 of this subpart).

(a) If the unit terminates, all committed NPR-A leases return to individual lease status and are subject to their original provisions.

(b) An NPR-A lease that has completed its primary term on or before the date the unit terminates will expire unless it is granted an extension or renewal under § 3135.1-5 or § 3135.1-6.

Within three months after unit termination, the unit operator must submit to BLM for approval a plan and schedule for mitigating the impacts resulting from unit operations. The plan must describe in detail planned plugging and abandonment and surface restoration operations. The unit operator must then comply with the BLM-approved plan and schedule.

(a) You may file for a State Director Review (SDR) of a decision BLM issues under this subpart. Part 3160, subpart 3165 of this title contains regulations on SDR; or

(b) If you are adversely affected by a BLM decision under this subpart you may directly appeal the decision under parts 4 and 1840 of this title.
