Benedum /Spraberry/ Unit #303 (API 42-461-31506) is a plugged well in Upton County, plugged December 14, 2023, last operated by Pioneer Natural Res. USA Inc..

The RRC has issued 2 drilling permits (amended twice) between 1979 and 1999, permitted to 11,600 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 2 formation tops, including Cretaceous, Spraberry.

Its 2 leases have reported 1.18M barrels of oil and 3.02M mcf of gas since January 1993, last reporting in July 2026. The leases carry 115 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.
