Cook Unit Iii Las #A 2H (API 42-283-34888) is a horizontal well in La Salle County operated by Ineos USA Oil & Gas LLC, completed December 21, 2014 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued July 11, 2014, permitted to 12,000 ft.

It was permitted by Chesapeake Operating, Inc. and has since transferred to Ineos USA Oil & Gas LLC on the wellbore schedule.

Completion filings report 10 formation tops, including Yegua, Queen City, Sparta, Wilcox.

Its lease has reported 615K barrels of oil and 451K mcf of gas since December 2014, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
