Andrews County · Shafter Lake (San Andres) field · Horizontal
Shafter Lake /San Andres/ Unit #129 W (API 42-003-03473) is a plugged horizontal well in Andrews County, plugged April 28, 2011, last operated by Hilcorp Energy Company.
The RRC has issued one drilling permit, issued May 4, 2003, permitted to 4,750 ft.
It was permitted by Westport Oil And Gas Company, LP and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 3 formation tops, including Grayburg, Queen, San Andres.
Its lease has reported 6.7M barrels of oil and 2.31M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 410 wells, so these are lease totals, not this well alone.
