The RRC has issued one drilling permit (amended once), issued February 27, 2015, permitted to 11,580 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 Santa Rosa, Yates, Queen, Grayburg.
Its lease has reported 185K barrels of oil and 506K mcf of gas since January 1993, last reporting in July 2026. The lease carries 9 wells, so these are lease totals, not this well alone.
