Wasson Odc Unit #668 (API 42-501-34055) is a well in Yoakum County operated by Occidental Permian Ltd., completed December 28, 2011 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued February 2, 1996, permitted to 5,327 ft.
It was permitted by Amoco Production Company and has since transferred to Occidental Permian Ltd. on the wellbore schedule.
Completion filings report 3 formation tops, including Rustler, Yates, San Andres.
Its lease has reported 117M barrels of oil and 293M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 848 wells, so these are lease totals, not this well alone.
