Benedum /Spraberry/ Unit #7501 (API 42-461-01485) is a plugged well in Upton County, plugged May 11, 2005, last operated by Pioneer Natural Res. USA Inc..

The RRC has issued one drilling permit, issued November 19, 1991, permitted to 7,500 ft.

It was permitted by Cox, John L. and has since transferred to Pioneer Natural Res. USA Inc. on the wellbore schedule.

Completion filings report 6 formation tops, including Grayburg, Spraberry, Pennsylvanian, Devonian.

Its 3 leases have reported 1.17M barrels of oil and 2.84M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 114 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.
