The RRC has issued 2 drilling permits (amended once) between 1984 and 2007, permitted to 3,000 ft.
It was permitted by Cavalier Oil & Gas, Inc. and has since transferred to Texian Operating Company LLC on the wellbore schedule.

Its 2 leases have reported 171K barrels of oil and 766 mcf of gas since January 1993, last reporting in July 2026. The leases carry 18 wells, so these are lease totals, not this well alone.
