Guinn #5 (API 42-451-31512) is a plugged well in Tom Green County, plugged October 7, 2015, last operated by Core Petro LLC.
The RRC has issued one drilling permit, issued November 19, 1984, permitted to 1,100 ft.
It was permitted by Focus Petroleum, Inc. and has since transferred to Core Petro LLC on the wellbore schedule.
Completion filings report one formation top, including San Angelo.
Its lease has reported 9.96K barrels of oil and 38 mcf of gas since January 1993, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
