The RRC has issued 2 drilling permits between 1995 and 2009, permitted to 5,500 ft.

It was permitted by Cimarex Energy CO. Of Colorado and has since transferred to Saddleback Exploration LLC on the wellbore schedule.

Its 2 leases have reported 13.1K barrels of oil and 1.46K mcf of gas since January 1993, last reporting in July 2026. The leases carry 5 wells, so these are lease totals, not this well alone.
