Andrews County · Shafter Lake (San Andres) field · Shut In · Vertical
Shafter Lake /San Andres/ Unit #441 (API 42-003-38600) is a well in Andrews County operated by Hilcorp Energy Company, completed May 13, 2000 and listed as shut in on the RRC schedule, shut in June 1, 2024.
The RRC has issued one drilling permit, issued March 30, 2000, permitted to 4,700 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.
