The RRC has issued one drilling permit (amended once), issued December 11, 2009, permitted to 10,450 ft.
It was permitted by Meritage Energy Company, LLC and has since transferred to Xto Energy Inc. on the wellbore schedule.

Its lease has reported 104K barrels of oil and 243K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
