Cooper Unit #1
Nolan County · Rowan & Hope (Penn. Reef) field · Vertical
Cooper Unit #1 (API 42-353-31086) is a plugged well in Nolan County, plugged December 11, 2013, last operated by Triple T Resources LP.
The RRC has issued one drilling permit, issued April 20, 1981, permitted to 6,800 ft.
It was permitted by Challenger Minerals Inc. and has since transferred to Triple T Resources LP on the wellbore schedule.
Completion filings report 7 formation tops, including B/Coleman Jct, B/Coleman Jct., Noodle Creek, Saddle Creek.
Its 2 leases have reported 95 barrels of oil and 109K mcf of gas since January 1993, last reporting in December 2013. The leases carry 2 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Challenger Minerals Inc.; the EWA schedule now lists a different operator.
