Shafter Lake Clearfork Unit #325W (API 42-003-38285) is a well in Andrews County operated by Highmark Energy Operating LLC, completed December 23, 1997 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued September 19, 1997, permitted to 7,010 ft.

It was permitted by Henry Petroleum Corp. and has since transferred to Highmark Energy Operating LLC on the wellbore schedule.

Completion filings report 3 formation tops, including San Andres, Clear Fork, Tubb.

Its lease has reported 5.61M barrels of oil and 1.5M mcf of gas since February 1995, last reporting in July 2026. The lease carries 79 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit.

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