Crestwood currently owns and operates three natural gas cryogenic processing units with aggregate capacity of 360 MMcfd. In the Barnett Shale, the Cowtown Plant, consists of two units and has a design capacity of 200 MMcfd; and the Corvette Plant has a design capacity of 125 MMcfd. In the Granite Wash, the Indian Creek Plant has a capacity of 36 MMcfd and the ability to expand as the play continues to develop. All of these plants use cryogenic processing to recover or extract a mixture of NGLs such as ethane, propane, butane and natural gasoline. The NGLs are sent through third-party pipelines to fractionation facilities in Mont Belvieu, Texas, where they are separated into a variety of petrochemical and refining feedstocks. Crestwood is paid a fixed-fee per MCF for the extraction of all NGLs from the natural gas gathered on its Barnett Shale gathering system and a blend of percentage-of-proceeds and fixed-fee arrangements for the NGLs recovered by the Indian Creek plant in the Granite Wash.
