The RRC has issued 2 drilling permits between 1998 and 1999, permitted to 13,920 ft.
It was permitted by Houston Exploration Company, The and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Its 2 leases have reported 1.61K barrels of oil and 5.42M mcf of gas since August 1998, with no volume in the three years through April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
