Mcgill J.C.JR.State #23 (API 42-427-31603) is a plugged well in Starr County, plugged January 28, 2010, last operated by Exxon Mobil Corporation.
The RRC has issued 4 drilling permits between 1981 and 1992, permitted to 9,700 ft.
It was permitted by Exxon Corp. and has since transferred to Exxon Mobil Corporation on the wellbore schedule.
Its 3 leases have reported 1.29K barrels of oil and 711 mcf of gas since January 1993, last reporting in March 2010. The leases carry 24 wells, so these are lease totals, not this well alone.
