It was permitted by Chesapeake Operating, Inc. and has since transferred to Cog Operating LLC on the wellbore schedule.

Its 2 leases have reported 59.8K barrels of oil and 171K mcf of gas since February 2009, last reporting in April 2019. The leases carry 2 wells, so these are lease totals, not this well alone.
