The Anadarko Basin is one of the deepest basins on the North American continent, encompassing roughly 35,000 square miles in western Oklahoma, the northern Texas Panhandle and Southwestern Kansas. In depth and volume, the Anadarko Basin is one of North America's major geologic features. It contains over 40,000 feet of potential hydrocarbon bearing sediments, constituting one of the thickest and most complete Paleozoic sections in the Mid-Continent structural province.
Numerous productive formations are found in the Anadarko Basin. The major producing horizons and the most common focus of the deep basin exploration are seven formations:
- Arbuckle (Cambio-Ordovician)
- Simpson (Ordovician)
- Hunton (late Ordovician-early Devonian)
- Springer (Pennsylvanian)
- Morrow (Pennsylvanian)
- Atoka (Pennsylvanian)
- Redfork (Pennsylvanian)
The Granite Wash formations (from Permian Wolfcamp-middle Pennsylvanian Atoka) also represent economically significant hydrocarbon objectives. The depth of these formations range from 10,000 to 30,000 feet. The majority of the Anadarko Minerals' production is from 13,000 to 18,000 feet, but this production holds leasehold rights for the future exploration and development at greater depths.
