Andrews Unit #551W (API 42-003-43230) is a well in Andrews County operated by Hilcorp Energy Company, completed January 20, 2020 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued August 3, 2011, permitted to 9,065 ft.

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

Completion filings report one formation top, including Wolfcamp.

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

It holds an active disposal or injection permit, with 57.7K 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.
