Munger Nix A Lzs #45 (API 42-003-42646) 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 February 11, 2011, 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 1.81M barrels of oil and 938K mcf of gas since January 1993, last reporting in July 2026. The lease carries 79 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 83.5K barrels injected in the 12 months reported through March 2026.
