The RRC has issued one drilling permit, issued October 30, 2003, permitted to 5,100 ft.
It was permitted by Walsh Petroleum, Inc. and has since transferred to A.C.T. Operating Company on the wellbore schedule.
Completion filings report 3 formation tops, including P-1 Zone, P-2 Zone, P-3 Zone.
Its lease has reported 52.5K barrels of oil and 108K mcf of gas since December 2003, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
