The RRC has issued one drilling permit, issued June 14, 2018, permitted to 12,000 ft.
It was permitted by Energen Resources Corporation and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Santa Rosa, Yates, Queen, Grayburg.
Its lease has reported 1.08M barrels of oil and 3.66M mcf of gas since September 2018, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
