State Tract 440 #4 (API 42-355-02561) is a plugged well in Nueces County, plugged August 6, 2014, last operated by Chaparral Energy L.L.C..
The RRC has issued one drilling permit, issued June 23, 1994, permitted to 7,395 ft.
It was permitted by Bristol Resources Corporation and has since transferred to Chaparral Energy L.L.C. on the wellbore schedule.
Completion filings report one formation top, including Common (Zone 10).
Its 2 leases have reported 11.6K barrels of oil and 976K mcf of gas since January 1993, last reporting in August 2014. The leases carry 11 wells, so these are lease totals, not this well alone.
