The Carter-Knox oil field, located in the southeastern end of the Anadarko basin in southeastern Grady and northeastern Stephens Counties, Oklahoma, covers an area of approximately 7 square miles, ½–¾ mile wide and 10 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 Hoxbar, Deese and Springer groups. The first oil well was completed in 1923; and some drilling is being done at the present time. Since 1923 the Carter-Knox field produced a total of 27,643,000 barrels of oil, as of May 1953. Production from the Springer since its discovery in March 1947 has been 6,573,140 barrels. In May 1953 the Carter-Knox field was producing 4,317 barrels of oil daily from 375 wells from all zones.
