Four C San Andres Unit #1 (API 42-371-32325) is a well in Pecos County operated by Saguaro Petroleum LLC, completed December 6, 1977 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued July 8, 1977, permitted to 2,370 ft.
It was permitted by Four C Oil & Gas Corp. and has since transferred to Saguaro Petroleum LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Yates, Grayburg, San Andres.
Its 2 leases have reported 1.25M barrels of oil and 35.7K mcf of gas since January 1993, last reporting in July 2026. The leases carry 39 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 12K barrels injected in the 12 months reported through May 2025.
