Guerra R. A. #4 (API 42-427-32040) is a plugged well in Starr County, plugged May 8, 2014, last operated by Harkins & Company.
The RRC has issued 4 drilling permits between 1985 and 1997, permitted to 11,500 ft.
It was permitted by M. J. G., Inc. and has since transferred to Harkins & Company on the wellbore schedule.
Completion filings report one formation top, including Vicksburg.
Its 3 leases have reported 179K barrels of oil and 221K 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.
