Wasson South Clearfork Unit #7535S (API 42-165-33943) is a well in Gaines County operated by Occidental Permian Ltd., completed July 10, 2001 and listed as shut in on the RRC schedule, shut in December 1, 2004.

The RRC has issued one drilling permit, issued March 18, 1988, permitted to 7,650 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 6 formation tops, including Rustler, Yates, Queen, San Andres.

Its 2 leases have reported 26.3M barrels of oil and 32.3M mcf of gas since January 1993, last reporting in July 2026. The leases carry 260 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit.

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