Robertson (San Andres) Unit #71 (API 42-165-35415) is a well in Gaines County operated by Occidental Permian Eor LLC, completed October 1, 1999 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued May 12, 1999, permitted to 5,000 ft.
It was permitted by Altura Energy Ltd. and has since transferred to Occidental Permian Eor LLC on the wellbore schedule.
Completion filings report 5 formation tops, including Rustler, Yates, Seven Rivers, Queen.
Its lease has reported 4.68M barrels of oil and 1.65M mcf of gas since January 1993, last reporting in July 2026. The lease carries 73 wells, so these are lease totals, not this well alone.
