It was permitted by Lario Oil & Gas Company and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Its lease has reported 891K barrels of oil and 733K mcf of gas since May 2019, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
