The RRC has issued one drilling permit (amended once), issued August 29, 2005, permitted to 12,013 ft.
It was permitted by Conocophillips Company and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Its 2 leases have reported 3 barrels of oil and 172K mcf of gas since January 2007, with no volume in the three years through April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
