Grayson County · Big Mineral Creek (UV Sand Unit) field · Vertical
Big Mineral Creek (UV Sand) Unit #436 (API 42-181-01692) is a well in Grayson County operated by Flintlock Exploration LLC, completed May 3, 1983.
The RRC has issued one drilling permit, issued March 3, 1981, permitted to 7,550 ft.
It was permitted by Shell Oil Company and has since transferred to Flintlock Exploration LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Strawn, Barnes, U Sand, V Sand.
Its 4 leases have reported 3.08M barrels of oil and 3.61M mcf of gas since January 1993, last reporting in July 2026. The leases carry 214 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 21.3K barrels injected in the 12 months reported through September 2025.
