Grayson County · Big Mineral Creek (UV Sand Unit) field · Shut In · Vertical
Big Mineral Creek (UV Sand) Unit #1 (API 42-181-01679) is a well in Grayson County operated by Flintlock Exploration LLC, completed December 4, 2023 and listed as shut in on the RRC schedule, shut in September 1, 2010.
The RRC has issued one drilling permit, issued April 20, 1990, permitted to 7,050 ft.
It was permitted by Shell Western E&P Inc. and has since transferred to Flintlock Exploration LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Strawn, Barnes 1, S-Sand, Baker (V-Lower).
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 236 wells, so these are lease totals, not this well alone.
