Anadarko
Basin

The Anadarko Basin is a deep sedimentary basin spanning western and central Oklahoma, the northern Texas Panhandle, and small portions of southwestern Kansas and southeastern Colorado. The basin is one of the deepest in North America, with sediments reaching more than 40,000 feet thick in its deepest part. For mineral owners, the relevant story is the modern stacked-pay horizontal development concentrated in central Oklahoma, where multiple formations remain economically productive at drillable depths.

Modern Anadarko Basin development is divided into three principal sub-plays. The SCOOP (South Central Oklahoma Oil Province) targets the Woodford Shale and Springer Sandstone primarily in Garvin, Grady, and Stephens counties. The STACK (Sooner Trend Anadarko Canadian Kingfisher) targets the Mississippian Meramec and Osage formations primarily in Canadian, Kingfisher, and Blaine counties. The Merge is the geographic overlap zone between SCOOP and STACK and produces from multiple horizons.

The basin’s operator base includes Devon Energy with a substantial STACK position, Continental Resources, ConocoPhillips through the legacy Marathon Oil position, Ovintiv, BP America, and several private operators. Occidental Petroleum’s Anadarko Basin presence came primarily through the 2019 Anadarko Petroleum acquisition. The Oklahoma Corporation Commission’s well search provides searchable access to permit data and operator records by API number.

Oklahoma’s forced-pooling framework is well-established and operators use it frequently. Pooling orders typically include a default royalty option (often 1/8) plus alternative election options at different royalty rates and bonus structures. For mineral owners receiving a pooling notice, the option to negotiate a voluntary lease before the OCC hearing is usually preferable to letting the default order terms apply.

In Oklahoma, Anadarko Basin development is concentrated in a corridor running through the central and western parts of the state. Canadian County sits at the heart of the STACK play and hosts substantial Meramec horizontal development. Kingfisher County extends the STACK play to the north and west. Blaine, Grady, Garvin, Custer, Dewey, Logan, and Major counties also host significant development across the SCOOP, STACK, and Merge sub-plays.

The Texas Panhandle portion of the basin extends into Hemphill, Wheeler, Lipscomb, and Roberts counties, with development at a more selective pace than the Oklahoma core. Some Anadarko Basin acreage sits in counties we have not yet built dedicated pages for, but we work mineral interests across the full basin footprint.

Mineral rights in the Anadarko Basin are valued based on which sub-play the tract sits in, what formations are productive at depth, and the operator’s development plans for the surrounding acreage. STACK tracts in Canadian and Kingfisher counties typically command strong valuations because the Meramec horizontal play has been a focus of operator capital for years. SCOOP tracts in Grady and Garvin counties are valued on Woodford and Springer development potential.

Royalty paperwork in the Anadarko Basin frequently shows multiple legacy operator names. Anadarko Petroleum (acquired by Occidental in 2019), Marathon Oil (acquired by ConocoPhillips in 2024), and several smaller acquired companies all appear on legacy paperwork. The underlying mineral interest carries over unchanged through each transaction; what changes is the company administering the payment. The current operator on any specific well can be confirmed through the Oklahoma Corporation Commission well search.

Oklahoma’s forced-pooling framework matters substantially for mineral owners. If you receive a pooling notice from the OCC, you generally have several options including a voluntary lease negotiated with the operator (usually preferable), participation as a working interest owner (rarely the right move for passive mineral owners), or accepting one of the default order options. Most owners benefit from the voluntary lease path. The default royalty options on pooling orders are often less favorable than what can be negotiated directly with the operator.

If you are considering selling mineral rights in the Anadarko Basin, we pull operator activity in your specific spacing unit, identify nearby permits and active drilling, look at lease and pooling order language, and produce a written analysis of what your interest is worth. We are happy to do this for any Anadarko Basin tract regardless of size or sub-play.
