North Robertson San Andres Unit #9 (API 42-165-33204) is a well in Gaines County operated by Citation Oil & Gas Corp., completed October 24, 2025 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued March 25, 1985, permitted to 4,719 ft.
It was permitted by Exxon Corp. and has since transferred to Citation Oil & Gas Corp. on the wellbore schedule.
Completion filings report 8 formation tops, including Tansil, Tansill, Yates, Seven Rivers.
Its 3 leases have reported 2.23M barrels of oil and 1.39M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 162 wells, so these are lease totals, not this well alone.
