Mcgill Bros. #M516 (API 42-047-31444) is a plugged well in Brooks County, plugged September 21, 2010, last operated by Hilcorp Energy Company.

The RRC has issued 4 drilling permits (amended twice) between 1985 and 1997, permitted to 9,200 ft.

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

Its 4 leases have reported 100K barrels of oil and 564K mcf of gas since January 1993, last reporting in July 2026. The leases carry 70 wells, so these are lease totals, not this well alone.
