Strain L. A. #12 (API 42-335-33863) is a well in Mitchell County operated by Unitex Oil & Gas L.L.C., completed June 17, 1997.
The RRC has issued one drilling permit, issued July 24, 1996, permitted to 1,700 ft.
It was permitted by Wjc, Inc. and has since transferred to Unitex Oil & Gas L.L.C. on the wellbore schedule.
Completion filings report 3 formation tops, including Yartes, Yates, San Andres.
Its lease has reported 371K barrels of oil and 21 mcf of gas since January 1993, last reporting in July 2026. The lease carries 15 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 12.4K barrels injected in the 12 months reported through July 2025.
