The RRC has issued 4 drilling permits between 1984 and 2001, permitted to 3,800 ft.
It was permitted by North Ridge Corporation and has since transferred to Dfg Energy Company LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Strawn, Marble Falls, Mccleskey, Duffer.
Its 5 leases have reported 11.6K barrels of oil and 90.7K mcf of gas since January 1993, last reporting in July 2026. The leases carry 30 wells, so these are lease totals, not this well alone.
