De Luna R. G. #12 (API 42-131-36177) is a plugged well in Duval County, plugged December 16, 2020, last operated by Texas Southern Petroleum Corp..
The RRC has issued one drilling permit, issued January 14, 1983, permitted to 6,000 ft.
It was permitted by Gathings Oil, Inc. and has since transferred to Texas Southern Petroleum Corp. on the wellbore schedule.
Completion filings report 3 formation tops, including T/Hockley, T/Pettus, T/Yegua.
Its 3 leases have reported 258 barrels of oil and 25.6K mcf of gas since January 1993, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
