Shafter Lake /San Andres/ Unit #504 (API 42-003-38614) is a plugged well in Andrews County, plugged February 28, 2025, last operated by Hilcorp Energy Company.

The RRC has issued one drilling permit, issued April 20, 2000, permitted to 5,000 ft.

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

Completion filings report 4 formation tops, including Yates, Queen, Grayburg, San Andres.

Its lease has reported 6.7M barrels of oil and 2.31M mcf of gas since January 1993, last reporting in July 2026. The lease carries 410 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.
