The RRC has issued one drilling permit, issued September 19, 2014, permitted to 7,500 ft.
It was permitted by Virtex Operating Company, Inc. and has since transferred to Trailblazer Energy Resources LLC on the wellbore schedule.

Its lease has reported 1.27M barrels of oil and 5.28M mcf of gas since September 2013, last reporting in July 2026. The lease carries 10 wells, so these are lease totals, not this well alone.
