The RRC has issued one drilling permit, issued April 28, 2006, permitted to 9,850 ft.
It was permitted by Pioneer Natural Res. USA, Inc. and has since transferred to Apache Corporation on the wellbore schedule.
Completion filings report 3 formation tops, including Queen, Grayburg, U. Spraberry.
Its 2 leases have reported 485K barrels of oil and 1.07M mcf of gas since January 1993, last reporting in July 2026. The leases carry 15 wells, so these are lease totals, not this well alone.
