The RRC has issued 2 drilling permits (amended once) between 1995 and 2006, permitted to 15,000 ft.
It was permitted by Swift Energy Operating, LLC and has since transferred to Prize Exploration & Prod LLC on the wellbore schedule.

Its 2 leases have reported 13.5K barrels of oil and 2.11M mcf of gas since July 1995, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
