The Kinta gas field comprises the former Cartersville, McCurtain, Lewisville, West Milton, Lequire, and Kinta gas fields. It is in Haskell County in the northern shelf area of the Arkoma basin. There are approximately 200 gas wells with a total reserve of more than 1 trillion cu ft of gas. Production is from the Spiro Sand (200 wells) of early Atokan age and from the Cromwell Sand (34 wells) of Morrowan age. Production first was established in 1916 from the Hartshorne Sandstone. This reservoir has been depleted. Key discoveries in the deeper Spiro and Cromwell were made by Superior Oil Company in 1951 at Kinta and by Red Bank Oil Company at Cartersville in 1930.

Anticlinal structure is shown in surface and subsurface strata, but the accumulation appears to be controlled stratigraphically by porosity of both the Spiro and Cromwell Sands. Porosity is the result of erratic sandstone deposition and is independent of structure. The area is cut by normal "growth" faults which show greater deposition of Atoka shale in the downthrown blocks. Water sands are present in the Spiro and Cromwell north of the Mulberry fault in Haskell County, and south of the fault gas generally is found where these sandstone units are porous.
