Guinn #1
Caldwell County · Luling-Branyon field · Vertical
Guinn #1 (API 42-055-31363) is a well in Caldwell County operated by Guinn Oil Company, completed May 27, 1980.
The RRC has issued one drilling permit, issued March 17, 1980, permitted to 2,400 ft.
It was permitted by Union Oil And Minerals Corp. and has since transferred to Guinn Oil Company on the wellbore schedule.
Its 2 leases have reported 12.6K barrels of oil and 3.53K mcf of gas since January 1993, last reporting in July 2026. The leases carry 4 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Union Oil and Minerals Corp.; the EWA schedule now lists a different operator.
