Mcgill Bros. #441 (API 42-427-30576) is a plugged well in Starr County, plugged October 26, 2000, last operated by Hilcorp Energy Company.
The RRC has issued 4 drilling permits (amended once) between 1978 and 1997, permitted to 7,848 ft.
It was permitted by Exxon Corp. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Its 3 leases have reported 102K barrels of oil and 570K mcf of gas since the record begins in January 1993, last reporting volume in August 2026. The leases carry 48 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Exxon Corp.; the EWA schedule now lists a different operator.

Surface location
No coordinates on the permit record yet. The RRC's GIS record usually lands within days of issuance; historical master-file permits never carry one.

Every well with a location on file around this well, in any state, nearest first.
Texas locations come from drilling permits, so most older Texas wells have none and are not listed.
