Big Mineral Creek (UV Sand) Unit #511W (API 42-181-01696) is a well in Grayson County operated by Venoco Inc., completed May 19, 1994.
The RRC has issued one drilling permit, issued November 18, 1993, permitted to 7,339 ft.
It was permitted by Shell Western E&P Inc. and has since transferred to Venoco Inc. on the wellbore schedule.
Completion filings report 4 formation tops, including Strawn, Barnes Sand, S Sdstn., Uv Sand.
Its 4 leases have reported 3.34M barrels of oil and 2.25M mcf of gas since January 1993, last reporting in July 2026. The leases carry 268 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 17.1K barrels injected in the 12 months reported through September 2025.
