The stations, which will be situated in Doddridge county of West Virginia, US, are expected to hold the capacity to handle 120 million standard cubic ft per day (MMscfd) of gas from the Marcellus shale upon completion in 2014.

In together, the turnkey compressor stations will include around 35,000 hp of compression, inlet separation and filtration, gas dehydration, power generation and distribution and station instrumentation and controls.

Crestwood Midstream Partners natural gas business unit president Heath Deneke said the projects are essential to company’s infrastructure development plans in the active Marcellus, connecting it to the market.

Valerus CEO Steve Gill said, "This contract is a testament to our demonstrated success in developing comprehensive surface facility production systems all over the world."
