Shafter Lake /San Andres/ Unit #515 (API 42-003-38883) is a well in Andrews County operated by Hilcorp Energy Company, completed June 28, 2002 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued September 12, 2001, 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 3 formation tops, including 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.
