Chadbourne Ranch 431 #2 (API 42-081-31472) is a plugged well in Coke County, plugged February 18, 2011, last operated by Enervest Operating L.L.C..
The RRC has issued 2 drilling permits (amended once) between 1987 and 1990, permitted to 5,800 ft.
It was permitted by Wolcott, ED Operating and has since transferred to Enervest Operating L.L.C. on the wellbore schedule.
Completion filings report 10 formation tops, including Palo Pinto, Goen, Top Goen, Base Goen.
Its 2 leases have reported 33.7K barrels of oil and 37.6K mcf of gas since January 1993, last reporting in May 2011. The leases carry 2 wells, so these are lease totals, not this well alone.
