The RRC has issued 2 drilling permits between 1977 and 2008, permitted to 4,970 ft.
It was permitted by Noble Energy Inc and has since transferred to Contango Resources Inc. on the wellbore schedule.

Its 4 leases have reported 3.34M barrels of oil and 1.03M mcf of gas since January 1993, last reporting in July 2026. The leases carry 67 wells, so these are lease totals, not this well alone.
