Big Mineral Creek (UV Sand) Unit #1 (API 42-181-01691) is a plugged well in Grayson County, plugged November 6, 2024, last operated by Flintlock Exploration LLC.
The RRC has issued one drilling permit, issued April 10, 1980, permitted to 7,215 ft.
It was permitted by Shell Oil Company and has since transferred to Flintlock Exploration LLC on the wellbore schedule.
Its 5 leases have reported 3.21M barrels of oil and 3.92M mcf of gas since January 1993, last reporting in July 2026. The leases carry 235 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Shell Oil Company; the EWA schedule now lists a different operator.
