Nix-South Unit #22 (API 42-003-41378) is a well in Andrews County operated by Montare Operating Ltd., completed May 14, 2010 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued January 13, 2010, permitted to 7,500 ft.
It was permitted by OK Arena Operating Company and has since transferred to Montare Operating Ltd. on the wellbore schedule.
Completion filings report 7 formation tops, including Rustler, Yates, Grayburg, San Andres.
Its lease has reported 131K barrels of oil and 94.3K mcf of gas since January 1993, last reporting in July 2026. The lease carries 17 wells, so these are lease totals, not this well alone.
