Wasson Odc Unit #634 (API 42-501-33556) is a well in Yoakum County operated by Occidental Permian Ltd., completed November 15, 2022 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued February 26, 1990, permitted to 5,233 ft.

It was permitted by Amoco Production Company and has since transferred to Occidental Permian Ltd. on the wellbore schedule.

Completion filings report 10 formation tops, including Rustler, Queen, Grayburg, San Andres.

Its lease has reported 118M barrels of oil and 294M mcf of gas since the record begins in January 1993, last reporting volume in August 2026. The lease carries 850 wells, so these are lease totals, not this well alone.

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