Munger Nix -B- #12 (API 42-003-44275) is a well in Andrews County operated by Montare Operating Ltd., completed May 1, 2023 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued May 4, 2012, permitted to 4,900 ft.

It was permitted by Sandridge Expl. And Prod., LLC and has since transferred to Montare Operating Ltd. on the wellbore schedule.

Completion filings report 10 formation tops, including Grayburg, San Andres, Clear Fork, Glorieta.

Its lease has reported 289K barrels of oil and 122K mcf of gas since January 1993, last reporting in July 2026. The lease carries 16 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 96.1K barrels injected in the 12 months reported through March 2026.

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