Harold J. Reedy, Howard A. Sykes


The Carter-Knox oil field, located in the southeastern end of the Anadarko basin in southeastern Grady County and northeastern Stephens County, Oklahoma, covers an area of approximately 16.5 square miles, 1.5 miles wide and 11 miles long. The structure is a very steeply dipping, faulted anticline, which was first mapped on the surface in 1916. It produces from the rocks of the Permian System, and the Hoxbar, Deese, Springer, and Simpson groups. The first oil well was completed in 1923. Since the discovery of oil in the Permain, the field has undergone several drilling cycles, the latest being the development of gas-condensate production in the Simpson group which began with a Bromide sand discovery in 1956. As of January 1958, the Carter-Knox field had produced a total of 33,581,015 barrels of oil; and on the same date was producing. 3,370 barrels of oil per day from 407 wells, from all zones.
