The RRC has issued one drilling permit, issued December 9, 2013, permitted to 7,500 ft.
It was permitted by Energen Resources Corporation and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 11 formation tops, including San Andres, Cisco, Dean, Grayburg.
Its 2 leases have reported 69.7K barrels of oil and 333K mcf of gas since April 2011, last reporting in July 2026. The leases carry 4 wells, so these are lease totals, not this well alone.
