Caldwell County · Salt Flat West field · Vertical
Cooper #1 (API 42-055-31399) is a plugged well in Caldwell County, plugged December 1, 2022, last operated by Iao Energy LLC.
The RRC has issued 2 drilling permits between 1980 and 2011, permitted to 2,850 ft.
It was permitted by Ccr Operating, LLC and has since transferred to Iao Energy LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Austin Chalk, Eagle Ford, Buda.
Its 3 leases have reported 2.48K barrels of oil and 3.05K mcf of gas since January 1993, last reporting in July 2026. The leases carry 20 wells, so these are lease totals, not this well alone.
