Bigby J. O. -14- #12 (API 42-173-00071) is a plugged well in Glasscock County, plugged March 5, 2019, last operated by Diamondback E&P LLC.
The RRC has issued one drilling permit, issued December 31, 1985, permitted to 8,350 ft.
It was permitted by Arco Oil & Gas CO. and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report one formation top, including Dean.
Its 3 leases have reported 187K barrels of oil and 1.36M mcf of gas since January 1993, last reporting in July 2026. The leases carry 11 wells, so these are lease totals, not this well alone.
