The RRC has issued 3 drilling permits (amended once) between 1977 and 1996, permitted to 6,950 ft.
It was permitted by Citation Oil & Gas Corp. and has since transferred to Ladd Petroleum Corp. on the wellbore schedule.
Its lease has reported 156K barrels of oil and 324K mcf of gas since January 1993, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
