State Tract 458 #6 (API 42-355-02828) is a plugged well in Nueces County, plugged August 9, 2014, last operated by Chaparral Energy L.L.C..
The RRC has issued 2 drilling permits (amended twice) between 1994 and 2001, permitted to 7,406 ft.
It was permitted by Chaparral (USA) Energy, Inc. and has since transferred to Chaparral Energy L.L.C. on the wellbore schedule.
Completion filings report 3 formation tops, including Common 10, Sand 10, Sand 9.
Its 3 leases have reported 11.6K barrels of oil and 163K mcf of gas since January 1993, last reporting in August 2014. The leases carry 12 wells, so these are lease totals, not this well alone.
