– Bill Barrett Corp., Denver, said it expensed four vertical wells in the quarter ended Sept. 30, 2009, at its Circus prospect in the Montana overthrust southeast of Helena.

The company focused on the Upper Cretaceous Cody shale, 900-2,000 ft thick at 3,000-7,000 ft, “to identify a large, repeatable natural gas resource play, but test results instead indicate more complex geology than anticipated that is not aligned with the company’s strategy and timeline for development.”

Barrett tested the Cody shale in three vertical wells drilled in 2008. Results varied but were noncommercial and included gas flows up to 1.1 MMcfd, oil flows up to 117 b/d, and large quantities of water.
