Starr County · Kelsey South (Zone 19-B S) field · Vertical
Mcgill J.C. JR. State #287 (API 42-427-00246) is a plugged well in Starr County, plugged December 20, 1995, last operated by Exxon Mobil Corporation.
The RRC has issued 2 drilling permits between 1987 and 1992, permitted to 8,500 ft.
It was permitted by Exxon Corp. and has since transferred to Exxon Mobil Corporation on the wellbore schedule.
Its 3 leases have reported 9.98K barrels of oil and 20.9K mcf of gas since January 1993, last reporting in July 2026. The leases carry 46 wells, so these are lease totals, not this well alone.
