Willard Unit #115C (API 42-501-33543) is a well in Yoakum County operated by Oxy USA Wtp LP, completed July 15, 1990 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued December 14, 1989, permitted to 5,500 ft.
It was permitted by Arco Oil & Gas CO. and has since transferred to Oxy USA Wtp LP on the wellbore schedule.
Completion filings report 2 formation tops, including Yates, San Andres.
Its lease has reported 65.4M barrels of oil and 195M mcf of gas since January 1993, last reporting in July 2026. The lease carries 876 wells, so these are lease totals, not this well alone.
