The RRC has issued one drilling permit, issued October 13, 2010, permitted to 5,500 ft.
It was permitted by Halek Energy L.L.C. and has since transferred to Robuck Petroleum LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Atoka, Chester, Barnett.
Its 2 leases have reported 8.17K barrels of oil and 94.1K mcf of gas since June 2011, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
