Spraberry Driver Unit #6 (API 42-173-31195) is a plugged well in Glasscock County, plugged March 22, 2023, last operated by Pioneer Natural Res. USA Inc..
The RRC has issued 2 drilling permits between 1981 and 1987, permitted to 8,570 ft.
It was permitted by Standard Oil Production Company and has since transferred to Pioneer Natural Res. USA Inc. on the wellbore schedule.
Completion filings report 5 formation tops, including Clear Fork, Trend Area Cl. Fk., Spraberry, Dean.
Its 3 leases have reported 39.3M barrels of oil and 144M mcf of gas since January 1993, last reporting in July 2026. The leases carry 907 wells, so these are lease totals, not this well alone.
