Shackelford County · Shackelford County Regular (Gas) field · Water Supply · Vertical
Cook Ranch #A201 (API 42-417-37594) is a well in Shackelford County operated by Stasney Well Service LLC, completed October 2, 2000 and listed as water supply on the RRC schedule, shut in February 1, 2026.
The RRC has issued 2 drilling permits between 1992 and 2000, permitted to 5,250 ft.
It was permitted by Breck Operating Corp. and has since transferred to Stasney Well Service LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Caddo, Mississippian, Ellenburger.
Its 3 leases have reported 106K barrels of oil and 717K mcf of gas since January 1993, last reporting in July 2026. The leases carry 7 wells, so these are lease totals, not this well alone.
