Martin Nellie C. #31 (API 42-003-45473) is a well in Andrews County operated by Unitex Oil & Gas L.L.C., completed September 28, 2017 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued June 24, 2013, permitted to 9,000 ft.
It was permitted by Lime Rock Resources II-A, L.P. and has since transferred to Unitex Oil & Gas L.L.C. on the wellbore schedule.
Completion filings report 13 formation tops, including Rustler, Tansel, Yates, Seven Rivers.
Its lease has reported 702K barrels of oil and 4.31M mcf of gas since December 2000, last reporting in July 2026. The lease carries 33 wells, so these are lease totals, not this well alone.
