The RRC has issued 2 drilling permits (amended once) between 1990 and 2009, permitted to 4,700 ft.
It was permitted by RR Ventures Limited Partnership and has since transferred to Dartex Energy Corporation on the wellbore schedule.

Its lease has reported 255K barrels of oil and 19 mcf of gas since January 1993, last reporting in July 2026. The lease carries 7 wells, so these are lease totals, not this well alone.
