It was permitted by Earthstone Operating, LLC and has since transferred to Zarvona Energy LLC on the wellbore schedule.

Its lease has reported 1.02M barrels of oil and 856K mcf of gas since April 2018, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
