It was permitted by Elk Meadows Resources LLC and has since transferred to Thresher Energy Inc. on the wellbore schedule.

Its 2 leases have reported 164K barrels of oil and 35.2K mcf of gas since April 2005, last reporting in July 2026. The leases carry 5 wells, so these are lease totals, not this well alone.
