The RRC has issued one drilling permit (amended once), issued August 5, 2024, permitted to 11,000 ft.
It was permitted by Endeavor Energy Resources L.P. and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Yates, Queen, Grayburg, San Andres.
Its lease has reported 1.93M barrels of oil and 2.59M mcf of gas since February 2025, last reporting in July 2026. The lease carries 13 wells, so these are lease totals, not this well alone.
