Harkins #4C (API 42-175-32004) is a plugged well in Goliad County, plugged May 10, 2021, last operated by Charro Operating L.L.C..
The RRC has issued one drilling permit (amended once), issued March 22, 1985, permitted to 5,500 ft.
It was permitted by Harwood Exploration, Inc. and has since transferred to Charro Operating L.L.C. on the wellbore schedule.
Completion filings report 4 formation tops, including Oakville, Catahoula, Frio, Vicksburg.
Its 2 leases have reported 301K barrels of oil and 885K mcf of gas since January 1993, last reporting in February 2023. The leases carry 7 wells, so these are lease totals, not this well alone.
