The RRC has issued one drilling permit, issued February 27, 2013, permitted to 12,000 ft.
It was permitted by E.G.L. Resources, Inc. and has since transferred to Cog Operating LLC on the wellbore schedule.

Its lease has reported 848K barrels of oil and 1.44M mcf of gas since August 2011, last reporting in July 2026. The lease carries 11 wells, so these are lease totals, not this well alone.
