Gibson Unit #508 (API 42-501-33809) is a well in Yoakum County operated by Occidental Permian Ltd., completed May 1, 2025 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued October 23, 1992, permitted to 8,130 ft.

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

Completion filings report 5 formation tops, including San Andres, Glorieta, Clear Fork, Tubb.

Its lease has reported 13.2M barrels of oil and 3.63M mcf of gas since the record begins in January 1993, last reporting volume in August 2026. The lease carries 209 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 3 barrels injected in the 12 months reported through September 2025.

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