It was permitted by Dominion Oklahoma Texas E&P, Inc and has since transferred to Samson Contour Energy E&P LLC on the wellbore schedule.

Its 3 leases have reported 6.94K barrels of oil and 568K mcf of gas since August 2006, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
