Willard Unit #148X (API 42-501-33091) is a well in Yoakum County operated by Oxy USA Wtp LP, completed July 31, 2025 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued September 19, 1986, permitted to 5,350 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 Grayburg, 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.

It holds an active disposal or injection permit, with 466 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.
