Editorial update: October 16, 2026. General educational information.

Federal mineral ownership, an operative federal lease, a Wyoming conservation order, an approved communitization agreement, and a federal unit agreement answer different questions. Verify the land description, effective dates, signed approvals, allocation schedule, and the present status of BLM policy. BLM Instruction Memorandum 2022-057 was rescinded February 27, 2025; IM 2025-012 and IM 2025-034 list September 30, 2028 as their expiration date, but should be checked for supersession and relevant regulatory revisions before reliance.

Start with mineral ownership and lease status

A private surface owner may hold no minerals, and a private mineral owner may share a drilling area with federally owned minerals. Determine the exact tract, federal or Indian mineral reservation if any, state/private mineral ownership, original land patent or later conveyance, BLM lease serial number, and lease or unit commitment. BLM MLRS public reports and GLO records and Master Title Plats are research aids; they do not replace the actual current county title chain or approved agency agreements.

Communitization agreements: 43 CFR §§ 3105.21–3105.24

A communitization agreement (CA) may be approved by BLM when a lease or part of one cannot be developed independently under an established spacing or development program (43 CFR § 3105.22). Under § 3105.21, the application is filed with the appropriate BLM office, identifies any departure from the current model form, certifies the necessary signatures, includes an Exhibit A tract map and an Exhibit B listing tracts and ownership, and should be submitted at least 90 calendar days before first production to facilitate royalty reporting. That 90-day provision is expressed as ‘should,’ not an unconditional statutory bar.

Section 3105.23 requires the separate tracts and production or royalty apportionment, identifies the operator, requires adequate protection of United States interests, and provides that a CA becomes effective for affected federal leases only upon approval. Federal lease-continuation and agreement-effective-date rules depend on the actual approved terms, first-production facts and, in some circumstances, state pooling-order timing. Section 3105.24 specifies an initial period and continuation provisions subject to the agreement’s terms. Examine approval letters and exhibits, not merely a submitted draft or an operator’s spreadsheet.

Exploratory unit agreements and participating areas: 43 CFR Part 3180

An exploratory unit agreement (UA) under 43 CFR Part 3180 coordinates development of an identified oil or gas area, often larger than one drilling spacing unit. Section 3181.2 addresses designation applications supported by maps and geological information; designation does not create an exclusive right to submit an agreement. Section 3181.3 requires all proper parties owning rights, title or interests in the deposits to be invited to join; for a nonjoining party, the proponent must submit evidence of reasonable joinder efforts when filing for approval, and provide reasons for nonjoinder when requested. State and Indian lands involve the separate approvals addressed in § 3181.4. Under § 3183.4, a unit agreement is not effective until the authorized officer executes the approval certification. Obtain the actual approved instrument and amendments.

A participating area (PA) is the part of an exploratory unit reasonably established as productive of the unitized substances in paying quantities or needed for unit operations, with production allocated as the unit agreement prescribes (43 CFR § 3180.0-5). Section 3183.5 addresses geological substantiation for PA approval or revision. Merely lying within a unit-area boundary does not mean that a tract participates in proceeds from every producing reservoir or period. Always obtain the unit agreement, Exhibits A and B, current PA maps, approval decisions and any amendments.

Pending allocations: Royalty Resiliency Act of 2024

For covered federal lease agreements, 30 U.S.C. § 1721(j) directs the Secretary to issue production-allocation determinations for unit and communitization agreements within 120 days of a request. While a determination remains pending, the lessee or designee generally reports and pays federal royalties using the proposed production-allocation schedule; after a determination, the lessee or designee must make necessary corrections by the end of the third month after receiving it. The statutory interest treatment depends on timely payments and other requirements. The subsection excludes agreements containing Indian lands.

BLM Instruction Memorandum 2025-012 describes its implementation, including provisional MLRS records, notices to ONRR, production reporting, and approval follow-up. These provisions concern federal royalty administration; they do not automatically approve an unexecuted CA, determine private mineral title, or guarantee that a private royalty owner’s checkstub uses the final approved decimal. If an operator’s payment changes after BLM approval, request the old and new allocation schedules and the effective production months.

Do not confuse commingling with communitization

Production commingling combines physical production streams for measurement or processing; a CA addresses production allocation and lease consequences across tracts. 43 CFR Subpart 3173 addresses site security and production handling, including commingling/allocation conditions and applications in §§ 3173.14–3173.15. Section 3173.19(c) states that a commingling and allocation approval does not modify the terms of the covered leases, units or CAs; off-lease measurement has separate provisions. BLM IM 2025-034 supplies interim direction following 2025 legislation. Read the regulations with the applicable statute, operative BLM direction and actual approvals, and check for later implementation or supersession before applying them.

Wyoming conservation orders do not replace federal approvals

A WOGCC spacing or compulsory pooling order establishes specified state regulatory conditions for a pool or reservoir. It does not, standing alone, establish federal mineral leasehold title or grant authority to produce unleased federal or Indian minerals. Review the WOGCC docket and signed order alongside BLM/BIA mineral status and the actual CA or UA. BLM IM 2022-057 concerning forced-pooling requests was rescinded February 27, 2025; it must be treated solely as historical background, not active agency instruction.

Federal leasing policy is a separate subject

BLM IM 2026-018, dated May 12, 2026, addresses leasing matters resulting from 2025 legislation, including expressions of interest, lease sales, noncompetitive leasing and royalty rates. It is not a replacement for the rescinded forced-pooling memorandum and does not supply the individual approvals required by 43 CFR Parts 3100 or 3180. Always inspect the lease, governing statute, current regulations and the actual approval.

Illustrative mixed-ownership problem

Assume a Wyoming 640-acre state drilling spacing unit includes private mineral tracts and a separately leased federal mineral tract. The WOGCC order may regulate spacing and state-law pooling. A CA application might propose how production is allocated across federal and private tracts. Until the owner obtains the final BLM approval and Exhibit B, the fact that a federal tract appears on the state map does not establish its legal commitment or final allocation. If an allocation remains pending, federal royalties may be reported on the proposed schedule under 30 U.S.C. § 1721(j), subject to the statute’s scope. A private owner’s division-order decimal still must be reconciled to title, lease, signed unit/CA instruments and applicable state law.

Owner document checklist

  • County legal description and deed chain; identify private, state, federal and Indian mineral tracts separately.
  • BLM lease serial numbers, MLRS case status, original lease and approved assignments.
  • WOGCC spacing or pooling docket, signed orders, effective dates, reservoir, tract map and amendments.
  • Approved federal CA and its signed Exhibit A tract map and Exhibit B ownership/allocation schedule.
  • If there is a UA: executed unit agreement and certification, approved participating areas and geological supporting orders.
  • Unit or CA application date, BLM final decision and any proposed versus final royalty allocation schedule.
  • Well API number, as-drilled location, product type and formation; ONRR/BLM reporting where federally applicable.
  • Operator royalty statements, historical and revised decimals, suspense/revenue adjustments and the responsible payor’s explanation.
  • Current agency policy and regulations on the date of the decision; distinguish active instructions from rescinded documents.

Primary authorities and source currency

Real Wyoming appellate dispute: a federal tract, two formations and separate orders

Union Pacific Resources Co. v. Texaco, Inc., 1994 WY 92, 882 P.2d 212, gives an unusually instructive real record. The 1981 operating agreement related to both a 760-acre Frontier Formation unit and a 640-acre Dakota Formation unit in the Bruff Field, Moxa Arch area. BLM owned mineral rights in an adjacent 120-acre portion of Section 22. Concern over drainage from a Dakota well led to a WOGCC order enlarging the Dakota spacing unit to 760 acres and to a separate compulsory pooling order. The Supreme Court held that spacing alone did not apportion production (¶ 61), examined the agreement’s relationship to the new orders, and left the separate challenge to the pooling order’s validity undecided (¶ 71).

This appellate record supports the core research sequence: (1) distinguish federal mineral title from the private working-interest agreement; (2) identify the reservoir-specific state spacing order; (3) examine a separate pooling or communitization instrument that allocates actual proceeds; and (4) inspect the final order and exhibits. The reported court opinion documents these underlying orders but is not itself a certified WOGCC order or BLM CA approval; those original files remain to be obtained.

How to retrieve a real Wyoming federal agreement file

Search BLM MLRS by serial number, case name and legal land description, retaining both the legacy WYW and the standardized modern case ID where available. Request the approval letter or certification, effective date, Exhibit A map, Exhibit B tract/ownership and percentage schedule, amendments, approved participating areas, first-production documents and related federal lease status. Compare these with the WOGCC Orders Search and hearing docket. BLM’s Wyoming Public Room provides record-copy assistance when an actual agreement or signed decision is unavailable online.

BLM’s Adjudicating Communitization Agreements training package includes sample approval letters and exercise materials referring to Wyoming orders 794-2024 and 132-2021 and serial records WYW149996 and WYW30211. These are training exercises; they should not be presented as independent proof that a particular operator holds a presently approved interest. Obtain the actual relevant MLRS/WOGCC file before citing any exercise as a real transaction.

Historical Frontier-only communitization: the limitation actually mattered

The Wyoming Supreme Court’s reported decision in Union Pacific Resources Co. v. Texaco identifies an October 7, 1981 Communitization Agreement incorporated into a private operating agreement. According to ¶69, the CA’s express coverage was limited to the Frontier Formation. It did not provide voluntary pooling for the enlarged Dakota Formation drilling unit when WOGCC later expanded Dakota spacing from 640 to 760 acres. Verify the covered formation, land, mineral ownership, approvals and governing instrument for each producing stream.

The June 13, 1991 Dakota pooling order’s reported working-interest percentages were: Amoco 45.4379%, Union Pacific 24.4246%, Wexpro 17.1950%, and Texaco 12.9425% (opinion ¶20). The Supreme Court expressly declined to decide the order’s validity (¶71). These are historical litigation facts, not proof of current BLM allocation or an individual royalty-owner pay decimal. The original signed Frontier CA, BLM approval and signed 1991 pooling order are not yet in the research archive.

Quality-control safeguard: approval and source dates

A lease-sale notice, training presentation, MLRS action summary, submitted CA, and approved CA are different evidence types. If two public source extracts show inconsistent effective dates for the same CA, do not choose a date by assumption. Verify the original signed agreement and approval decision and log the discrepancy in the research registry. The notice of an existing CA also does not adjudicate all private or state mineral interests within the described land.

Official federal sources were consulted for this guide. Specific BLM approvals, selected Wyoming field orders, individual lease files and private title instruments have not been examined. Obtain the signed agreements, approvals and schedules before applying an allocation to a particular property. General education only; any professional services require a separate written agreement.
