West Welch Unit #720 (API 42-115-32652) is a plugged well in Dawson County, plugged March 13, 2023, last operated by Hilcorp Energy Company.

The RRC has issued one drilling permit, issued January 3, 1991, permitted to 4,970 ft.

It was permitted by Oxy USA Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Completion filings report 2 formation tops, including Yates, San Andres.

Its lease has reported 20.5M barrels of oil and 7.45M mcf of gas since the record begins in January 1993, last reporting volume in August 2026. The lease carries 687 wells, so these are lease totals, not this well alone.

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