Anton-Irish Clearfork Unit #490 (API 42-303-31025) is a well in Lubbock County operated by Occidental Permian Ltd., completed October 1, 2023 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued June 5, 1984, permitted to 6,334 ft.

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

Completion filings report 5 formation tops, including Red Beds, Ruslter Anhydrite, Yates, Tubb.

Its lease has reported 66.1M barrels of oil and 34.9M mcf of gas since January 1993, last reporting in July 2026. The lease carries 591 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 1.44K barrels injected in the 12 months reported through March 2026.

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