Flanagan Unit #531 (API 42-165-34625) is a well in Gaines County operated by Occidental Permian Eor LLC, completed May 17, 2018 and listed as shut in on the RRC schedule.

The RRC has issued 2 drilling permits between 1993 and 2017, permitted to 7,350 ft.

It was permitted by Occidental Permian Ltd. and has since transferred to Occidental Permian Eor LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Yates, San Andres, Glorieta, Clear Fork.

Its lease has reported 15.9M barrels of oil and 5.02M mcf of gas since January 1993, last reporting in July 2026. The lease carries 220 wells, so these are lease totals, not this well alone.
