Kelsey Unit #M 20E (API 42-047-01671) is a plugged well in Brooks County, plugged May 8, 2007, last operated by Hilcorp Energy Company.

The RRC has issued 4 drilling permits (amended once) between 1983 and 1989, permitted to 8,500 ft.

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

Its 2 leases have reported 246K barrels of oil and 483K mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 36 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
