The RRC has issued 2 drilling permits between 2005 and 2013, permitted to 15,000 ft.
It was permitted by Chesapeake Operating, Inc. and has since transferred to Chesapeake Operating L.L.C. on the wellbore schedule.
Completion filings report 5 formation tops, including Base Hebner, B. Heebner, Tonkawa, Missourian.
Its 2 leases have reported 15K barrels of oil and 475K mcf of gas since October 2005, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
