Benedum /Spraberry/ Unit #2103 (API 42-461-31989) is a plugged well in Upton County, plugged November 25, 2013, last operated by Pioneer Natural Res. USA Inc..
The RRC has issued 3 drilling permits between 1982 and 1992, permitted to 11,900 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 5 formation tops, including Redbeds, Spraberry, Pbtd, Dean.
Its 2 leases have reported 1.17M barrels of oil and 2.84M 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.
