The RRC has issued one drilling permit, issued August 28, 2012, permitted to 6,669 ft.
It was permitted by Linn Operating, Inc. and has since transferred to Unbridled Resources LLC on the wellbore schedule.

Its lease has reported 109K barrels of oil and 1.2M mcf of gas since May 2011, last reporting in July 2026. The lease carries 8 wells, so these are lease totals, not this well alone.
