It was permitted by Piedra Operating, LLC and has since transferred to Ovintiv USA Inc. on the wellbore schedule.

Its 2 leases have reported 547K barrels of oil and 917K mcf of gas since January 2012, last reporting in July 2026. The leases carry 7 wells, so these are lease totals, not this well alone.
