Big Mineral Creek/Strawnii/Unit #421 (API 42-181-01825) is a plugged well in Grayson County, plugged October 31, 2024, last operated by Venoco Inc..

The RRC has issued one drilling permit, issued January 8, 1987, permitted to 3,651 ft.

It was permitted by Shell Western E&P Inc. and has since transferred to Venoco Inc. on the wellbore schedule.

Completion filings report one formation top, including Strawn.

Its 3 leases have reported 2.91M barrels of oil and 1.39M mcf of gas since January 1993, last reporting in July 2026. The leases carry 231 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
