The RRC has issued one drilling permit, issued September 9, 2013, permitted to 13,000 ft.
It was permitted by Enervest Operating, L.L.C. and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 5 formation tops, including Clear Fork, Spraberry, Wolfcamp, Strawn.
Its lease has reported 291K barrels of oil and 759K mcf of gas since September 2008, last reporting in July 2026. The lease carries 7 wells, so these are lease totals, not this well alone.
