The RRC has issued one drilling permit, issued May 16, 2003, permitted to 12,000 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 5 formation tops, including Spraberry, Dean, Wolfcamp, Strawn.
Its lease has reported 421K barrels of oil and 1.96M mcf of gas since February 2003, last reporting volume in April 2026. The lease carries 8 wells, so these are lease totals, not this well alone.
