McGill Bros. #458
Starr County · Kelsey (Frio Consol.) field · Vertical
Mcgill Bros. #458 (API 42-427-31353) is a plugged well in Starr County, plugged July 21, 2011, last operated by Exxon Mobil Corporation.
The RRC has issued 4 drilling permits (amended once) between 1979 and 1996, permitted to 7,100 ft.
It was permitted by Exxon Corp. and has since transferred to Exxon Mobil Corporation on the wellbore schedule.
Its 2 leases have reported 20 barrels of oil and 4.51K mcf of gas since January 1993, last reporting in July 2011. The leases carry 3 wells, so these are lease totals, not this well alone.
