Ridgeline Energy Services Inc. said it plans to construct a water treatment facility in the Marcellus Shale near Punxsutawney, PA. The Calgary-based company said it had executed an agreement for an initial single train commercial installation (STCI) that would concentrate on produced water, with an anchor customer providing about 2,500-4,000 b/d of wastewater. Ridgeline said it was looking to build additional permanent installations in the same production area and expand its presence in western Pennsylvania. Installation of the first STCI is to begin in about a month.
