Capstone Turbine Corp. has increased the use of its microturbines in oil and natural gas production with sales in Texas and the eastern U.S.

The microturbines made by the Chatsworth company will be used in the Eagle Ford shale in Texas and the Marcellus Shale in Pennsylvania, West Virginia and western Ohio.

The Eagle Ford shale purchase was for systems that can generate three megawatts of power for the onsite equipment. Multiple oil and gas producers in the Marcellus shale ordered microturbine systems that can generate 4.2 megawatts for prime power and combined heat and power applications.

“Because our durable, clean-and-green microturbines use patented air bearing technology, operational costs can be significantly reduced,” said Jim Crouse, executive vice president of sales and marketing, in a prepared statement. “That's a key reason Capstone microturbines are being adopted as the go-to power source for onshore and offshore oil and gas applications around the world.”
