Mcgill Bros. #489 (API 42-427-31664) is a plugged well in Starr County, plugged July 14, 2010, last operated by Hilcorp Energy Company.

The RRC has issued 5 drilling permits (amended once) between 1982 and 1997, permitted to 10,000 ft.

It was permitted by Exxon Corp. and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Its 4 leases have reported 105K barrels of oil and 802K mcf of gas since January 1993, last reporting in July 2026. The leases carry 49 wells, so these are lease totals, not this well alone.
