State-by-state breakdown of regulatory bodies, key formations, income tax rules, forced pooling laws, and direct buyer access for every major oil and gas producing state.
TL;DR Selling mineral rights is not the same process in every state. The regulatory body, forced pooling law, state income tax rate on sale proceeds, and key formations vary by state. Texas has no state income tax and limited forced pooling through its Railroad Commission. Oklahoma's OCC issues forced pooling orders. Pennsylvania is the only major Marcellus state without forced pooling. California's income tax reaches 13.3%. Buckhead Energy buys mineral rights in all 50 states and provides free written valuations regardless of state.
Selling mineral rights is not the same process in every state. The regulatory body that oversees permits and pooling, the state income tax rate on proceeds, whether or not operators can force pool non-consenting owners, and the formations driving current value all vary by state. A mineral owner in Pennsylvania faces a completely different regulatory landscape than one in Oklahoma — even if both own royalties in an active gas well.
This page is the top-level directory. Each state section below identifies the key facts and links to the state-specific detailed guide. We buy in all 50 states. The depth of our state guides reflects where the largest concentration of mineral owners has the most questions.

Tax rates are state income tax on capital gains and are provided as general reference only. Effective rates depend on income level and individual circumstances. Forced pooling designations reflect whether the state has a mechanism by which operators can integrate non-consenting mineral owners into a drilling unit without a voluntary lease. Consult a CPA for tax advice specific to your situation.
Railroad Commission (RRC) | No state income tax
The largest oil and gas producing state in the US. Permian Basin (Midland + Delaware) leads; Eagle Ford in South Texas; Haynesville in East Texas. Texas has no state income tax on capital gains — a significant advantage for sellers. The RRC does not issue forced pooling orders like Oklahoma's OCC, though voluntary pooling is common in horizontal units.
Texas Seller's Guide →Corporation Commission (OCC) | 4.75% income tax
Home to SCOOP, STACK, and the Anadarko Basin. Oklahoma's OCC issues forced pooling orders — the most important process for OK mineral owners to understand before and during a sale. The Cherokee Platform and Mid-Continent region have long production histories. GPT withholding applies to royalties at the state level.
Oklahoma Seller's Guide →NMOCD | 5.9% income tax
The Permian Basin extends into Lea and Eddy counties — one of the most active drilling regions in the world. The San Juan Basin (Rio Arriba, San Juan counties) drives gas production in northwestern NM. NMOCD issues integration orders that function as forced pooling. OXY Permian dominates southeastern NM alongside Chevron, EOG, and Devon.
New Mexico Seller's Guide →WV DEP | Up to 6.5% income tax
Marcellus Shale dominates WV's shale production with wet gas in the northwest (Marshall, Wetzel, Doddridge) and dry gas in the central counties (Monongalia, Preston, Lewis). EQT, Antero, and CNX are the major operators. West Virginia has forced pooling provisions. Many WV mineral owners hold fractional interests in very old oil and gas leases — some dating to the late 1800s.
West Virginia Seller's Guide →PA DEP | 3.07% flat income tax
The largest Marcellus Shale producing state — northeastern PA for dry gas, southwestern PA for wet gas/NGLs. Pennsylvania is the only major shale state without forced pooling, giving PA mineral owners more negotiating leverage than their OK or WV counterparts. Pennsylvania has no severance tax (an impact fee replaces it), and its flat 3.07% income tax rate is one of the lowest of any major producing state.
Pennsylvania Seller's Guide →NDIC | Very low state income tax
The Williston Basin's Bakken and Three Forks formations make McKenzie, Mountrail, Williams, and Dunn counties among the most active drilling counties in the US. Bakken crude is light sweet (~42° API) and commands near-WTI prices. NDIC uses forced pooling to integrate spacing units. Continental Resources, ConocoPhillips, Hess, and Chord Energy (formerly Whiting) are the major operators. Many ND mineral owners live in Minnesota, Wisconsin, or other Midwest states.
North Dakota Seller's Guide →IDNR Oil and Gas Division | 4.95% flat income tax
The Illinois Basin spans southern Illinois (plus southwestern Indiana and western Kentucky) with a 130-year production history. Wayne, White, and Hamilton counties lead production through waterflood operations. The New Albany Shale adds speculative upside beneath existing conventional production. No forced pooling. Many interests are deeply fractional, inherited from the 1940s boom.
Illinois Seller's Guide →CalGEM | Up to 13.3% income tax
Kern County's San Joaquin Valley fields (Midway-Sunset, Kern River, Belridge) are among the largest in US history by cumulative production. California uses steam injection for heavy oil recovery. SB 1137 imposes 3,200-foot setbacks on new wells near sensitive receptors. California's income tax reaches 13.3% — the highest state rate of any producing state — and non-resident sellers face mandatory withholding at closing.
California Seller's Guide →WOGCC | Zero state income tax
The Powder River Basin (northeast Wyoming — Campbell, Converse, Johnson counties) hosts active Devon Energy and Continental Resources Niobrara and Turner horizontal programs. The Green River Basin (Pinedale Anticline, Jonah Field) is one of the largest onshore natural gas fields in North America. Wyoming has no state income tax — the same tax advantage as Texas — making WY one of the most favorable states for mineral sales.
Wyoming Seller's Guide →MBOGC | Up to 6.75% income tax
The Montana Bakken occupies the western margin of the Williston Basin in eastern Montana. Richland County — home to the historic Elm Coulee Field, one of the largest Bakken discoveries in the US — is the most active Montana Bakken county, with ConocoPhillips, XTO Energy (ExxonMobil), and Chord Energy as primary operators. Montana Bakken commands a discount to North Dakota core four pricing, reflecting the basin-margin position. MBOGC forced pooling applies to horizontal Bakken units.

Forced pooling (called "integration" in some states) allows an operator to include a non-consenting mineral owner in a drilling unit without a voluntary lease. States with forced pooling: Oklahoma, New Mexico, North Dakota, West Virginia, and many others. States without forced pooling: Texas (largely), Pennsylvania, Illinois, California. The practical impact: in forced-pooling states, mineral owners who don't lease may receive a reduced or penalized interest in a well; in non-pooling states, operators cannot develop without a signed lease.
The spread is enormous: Texas and North Dakota are at or near zero; Pennsylvania is a flat 3.07%; Oklahoma is 4.75%; New Mexico is 5.9%; West Virginia reaches 6.5%; California reaches 13.3%. For a $500,000 mineral sale, the state income tax difference between Texas (zero) and California (up to 13.3%) is $66,500 — a material factor in timing and structuring decisions. A 1031 exchange defers federal and state tax in all states (with California requiring FTB notification).
California's CalGEM and SB 1137 represent one end of the regulatory spectrum; Texas's RRC and North Dakota's NDIC represent the other. The regulatory trajectory of a state affects how buyers price future development potential — the upside credit on undeveloped or non-producing acreage is meaningfully different in a permissive vs. constrained regulatory environment. This is why California minerals trade at a discount to Texas minerals with comparable production.
The Permian Basin (Texas and New Mexico) commands the highest multiples on active producing royalties due to operator activity, well economics, and remaining inventory. Bakken (North Dakota) and Marcellus (Pennsylvania, West Virginia) are strong markets for gas royalties when gas prices are favorable. Illinois Basin and California assets are valued at lower multiples due to production profile and regulatory factors, respectively.
Yes. Most mineral rights owners live in a different state than their minerals. The transaction is handled remotely — documents by mail or overnight courier, signatures notarized locally, funding by wire. Non-residents may be subject to the mineral state's income tax on the gain and must file a return in the state where the minerals are located. See each state's guide for details.
No. What matters is that the buyer has specific expertise in the state where the minerals are located — they must understand the regulatory body, the formations, the title chain requirements, and the recording system in the mineral state. Buckhead Energy is licensed to acquire interests in all 50 states and has in-house expertise in every major producing region.
