Russell Clearfork Unit #223 (API 42-165-31597) is a plugged well in Gaines County, plugged August 24, 2025, last operated by Hilcorp Energy Company.

The RRC has issued one drilling permit, issued April 9, 1979, permitted to 7,800 ft.

It was permitted by Mobil Oil Corporation and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Completion filings report 8 formation tops, including Yates, Seven Rivers, Queen, Grayburg.

Its 3 leases have reported 21M barrels of oil and 13.4M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 1,101 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.
