McGill Bros. #525
Starr County · Kelsey (Frio Consol.) field · Vertical
Mcgill Bros. #525 (API 42-427-32057) is a plugged well in Starr County, plugged December 10, 2010, last operated by Exxon Mobil Corporation.
The RRC has issued 2 drilling permits (amended once) between 1985 and 1993, permitted to 7,600 ft.
It was permitted by Exxon Corp. and has since transferred to Exxon Mobil Corporation on the wellbore schedule.
Its 2 leases have reported 295K mcf of gas since January 1993, with no volume in the three years through April 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
