The South Thrifty Lease has a history of production. Since the field was opened in the 80's there have been over 180,000 barrels of oil produced and over 4.1 billion cubic feet of natural gas produced from this field. The Hunt A-1 well that was spud in 1988 originally flowed at over 792 barrels per day, with 19 thousand cubic feet of gas per day. There are 24 wells, one water injection well, and four tank batteries on the property. These wells are primarily gas producers.

Organic-rich Barnett Shale is the primary source rock for oil and gas that is produced from Paleozoic reservoir rocks in the Bend Arch-Fort Worth Basin Province. Areal distribution of hydrocarbons in this mature petroleum province indicates generation and expulsion from the Barnett Shale of the Fort Worth Basin. These Barnett-sourced hydrocarbons migrated westward into the reservoir rocks of the Bend Arch where South Thrifty is located. With the Barnett being the source of hydrocarbon development in the Chappel Reef, a geological and reserve assessment report was done 5 years ago on South Thrifty indicating the Chappel Reef could have a minimum of 2 million and up to 7 million barrels of recoverable oil.
