Edsall - Polk C.S.L. Unit #1 (API 42-447-34143) is a plugged well in Throckmorton County, plugged September 8, 1997, last operated by Spence Energy Company.
The RRC has issued 2 drilling permits (amended once) between 1984 and 1993, permitted to 5,200 ft.
It was permitted by Exp, Inc. and has since transferred to Spence Energy Company on the wellbore schedule.
Completion filings report 2 formation tops, including Caddo, Mississippian.
Its 2 leases have reported 9.15K barrels of oil and 54 mcf of gas since January 1993, last reporting in December 1997. The leases carry 2 wells, so these are lease totals, not this well alone.
