The RRC has issued one drilling permit (amended twice), issued October 26, 2004, permitted to 8,202 ft.
It was permitted by Cimarex Energy CO. and has since transferred to Assent Energy Partners LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Barnett, Chester, Meramec Shale.
Its 2 leases have reported 446K barrels of oil since May 2005, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
