The RRC has issued 2 drilling permits (amended once) between 2003 and 2012, permitted to 11,000 ft.
It was permitted by Chinn Exploration Company and has since transferred to Sydri Operating LLC on the wellbore schedule.

Its 2 leases have reported 36.4K barrels of oil and 685K mcf of gas since October 2003, last reporting in July 2026. The leases carry 4 wells, so these are lease totals, not this well alone.
