South Robertson (San Andres) U. #1508 (API 42-165-35455) is a well in Gaines County operated by Contango Resources Inc., completed February 23, 2001.

The RRC has issued one drilling permit, issued August 30, 1999, permitted to 4,820 ft.

It was permitted by Samedan Oil Corporation and has since transferred to Contango Resources Inc. on the wellbore schedule.

Completion filings report 5 formation tops, including Rustler, Yates, Queen, Grayburg.

Its 2 leases have reported 3.45M barrels of oil and 734K mcf of gas since August 1995, last reporting in July 2026. The leases carry 115 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.
