Duke Ranch -9- #1 (API 42-175-33881) is a plugged well in Goliad County, plugged March 1, 2012, last operated by T-C Oil Company LLC.

The RRC has issued one drilling permit, issued February 3, 2006, permitted to 7,000 ft.

It was permitted by T - C Oil Company and has since transferred to T-C Oil Company LLC on the wellbore schedule.

Completion filings report 5 formation tops, including Lagarto, Miocene (undifferentiated), Oakville, Catahoula.

Its 2 leases have reported 6.88K barrels of oil and 1.19M mcf of gas since April 2006, last reporting in October 2012. The leases carry 2 wells, so these are lease totals, not this well alone.
