It was permitted by Range Production Company and has since transferred to Oxy USA Inc. on the wellbore schedule.

Its 2 leases have reported 476K barrels of oil and 931K mcf of gas since May 2010, last reporting in July 2026. The leases carry 5 wells, so these are lease totals, not this well alone.
