South Mallet Unit #21-A (API 42-079-30825) is a permitted well in Cochran County filed by Texaco Inc.; no completion report is on file yet.
The RRC has issued one drilling permit, issued December 2, 1977, permitted to 5,000 ft.
It was permitted by Texaco Inc. and has since transferred to Winn Operating LLC on the wellbore schedule.
Its 2 leases have reported 926K barrels of oil and 615K mcf of gas since the record begins in January 1993, last reporting volume in August 2026. The leases carry 198 wells, so these are lease totals, not this well alone.
