Starr County · Kelsey (Frio Consol.) field · Vertical

Mcgill Bros. #396 (API 42-427-04994) is a plugged well in Starr County, plugged September 25, 2008, last operated by Hilcorp Energy Company.

The RRC has issued 3 drilling permits between 1977 and 1989, permitted to 6,350 ft.

It was permitted by Exxon Corp. and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Its 3 leases have reported 175K barrels of oil and 715K mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 53 wells, so these are lease totals, not this well alone.
