The RRC has issued one drilling permit, issued October 16, 1997, permitted to 7,200 ft.

It was permitted by Hugoton Energy Corporation and has since transferred to Pioneer Natural Res. USA Inc. on the wellbore schedule.

Completion filings report 5 formation tops, including Upr. Sprby, Middle Sprby, Jo Mill, Dean.

Its lease has reported 22.2K barrels of oil and 107K mcf of gas since December 1997, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
