The RRC has issued one drilling permit, issued August 11, 2017, permitted to 9,700 ft.
It was permitted by Qep Energy Company 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 2.9M barrels of oil and 9.76M mcf of gas since April 2018, last reporting in July 2026. The lease carries 14 wells, so these are lease totals, not this well alone.
