Flanagan Unit #77 (API 42-165-01463) is a well in Gaines County operated by Shell Western E&P Inc., completed February 9, 1982.

The RRC has issued 2 drilling permits between 1990 and 2016, permitted to 7,500 ft.

It was permitted by Occidental Permian Ltd. and has since transferred to Shell Western E&P Inc. on the wellbore schedule.

Completion filings report 7 formation tops, including Tansill, Yates, Grayburg, San Andres.

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.

It holds an active disposal or injection permit, with 40 barrels injected in the 12 months reported through October 2025.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
