The Mills Ranch complex is fast developing into one of the largest fields in the deep Anadarko Basin. This complex is part of a deeply buried granite uplift which extends northwest to southeast for 15 m (24 km) or more from Wheeler County, Texas, into Beckham County, Oklahoma. It is a long narrow anticlinal feature paralleling a northwest- to southeast-striking thrust fault and is complicated by numerous faults and unconformities. The discovery well of deep Mills Ranch-Hunton play which started a large drilling program was the Freeport Oil Co. 1 Sidney Fabian which was drilled in 1972 to a depth of 21,640 ft (6,596 m) and completed at a calculated open flow rate of 93,050 Mcfd. Since that time a continuous program, chiefly by the Chevron-Freeport Group, has proved at least 3 separate productive reservoirs in the Hunton. The Hunton section averages 929 ft (283 m) in thickness, and produces from both the Chimneyhill and the Henryhouse sections. Wells in the Hunton on the main structure are capable of producing up to 20,000 Mcfd.
