Gaines County · Robertson N. (San Andres) field · Water Supply · Vertical
Robertson (San Andres) Unit #5S (API 42-165-00885) is a well in Gaines County operated by Hilcorp Energy Company, completed December 28, 1987 and listed as water supply on the RRC schedule, shut in February 1, 2026.
The RRC has issued one drilling permit, issued May 3, 1989, permitted to 7,145 ft.
It was permitted by Shell Western E&P Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Its lease has reported 4.68M barrels of oil and 1.65M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 73 wells, so these are lease totals, not this well alone.
