McGill Bros. #221
Brooks County · Kelsey (Frio Consol.) field · Vertical
Mcgill Bros. #221 (API 42-047-00993) is a plugged well in Brooks County, plugged January 27, 2011, last operated by Exxon Mobil Corporation.
The RRC has issued 2 drilling permits between 1978 and 1994, permitted to 6,400 ft.
It was permitted by Exxon Corp. and has since transferred to Exxon Mobil Corporation on the wellbore schedule.
Its 2 leases have reported 129K mcf of gas since the record begins in January 1993, with no volume in the three years through April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
