The RRC has issued one drilling permit (amended twice), issued September 11, 1998, permitted to 9,175 ft.
It was permitted by Pioneer Natural Res. USA, Inc. and has since transferred to R2q Operating LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Canyon, Pennsylvanian, Penn7890, Strawn.
Its 3 leases have reported 2.06K barrels of oil and 931K mcf of gas since February 2001, last reporting volume in February 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
