It was permitted by Sinclair Oil Corporation and has since transferred to Sinclair Oil & Gas Company on the wellbore schedule.

Its 2 leases have reported 73.5K barrels of oil and 60K mcf of gas since March 1995, last reporting in September 2020. The leases carry 2 wells, so these are lease totals, not this well alone.
