Robertson (San Andres) Unit #1 (API 42-165-31241) is a well in Gaines County operated by Hilcorp Energy Company, completed March 11, 2000 and listed as shut in on the RRC schedule, shut in September 1, 2021.

The RRC has issued 2 drilling permits in 1978, permitted to 7,300 ft.

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

Completion filings report 6 formation tops, including Rustler, Seven Rivers, Queen, San Andres.

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.

It holds an active disposal or injection permit.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
