Texas -AA- #12 (API 42-003-36494) is a well in Andrews County operated by Maverick Operating LLC, completed November 12, 1989.

The RRC has issued 4 drilling permits (amended once) between 1989 and 2000, permitted to 11,500 ft.

It was permitted by Merit Energy Company and has since transferred to Maverick Operating LLC on the wellbore schedule.

Completion filings report 5 formation tops, including Yates, Tubb, Wolfcamp, Devonian.

Its 4 leases have reported 1.15M barrels of oil and 1.82M mcf of gas since January 1993, last reporting in July 2026. The leases carry 18 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.
