Andrews Unit #231 (API 42-003-38632) is a well in Andrews County operated by Hilcorp Energy Company, completed January 16, 2008 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued May 26, 2000, permitted to 9,300 ft.

It was permitted by Belco Energy Corp. and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Completion filings report 5 formation tops, including Glorieta, Clear Fork, Wichita-Albany, Wolfcamp.

Its lease has reported 9.38M barrels of oil and 8.35M mcf of gas since July 1996, last reporting in July 2026. The lease carries 97 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 83.6K barrels injected in the 12 months reported through February 2026.

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