Water cleaning technology could reduce environmental impacts from shale production
May 2, 2011

A novel water cleaning technology currently being tested in field demonstrations could help significantly reduce potential environmental impacts from producing natural gas from the Marcellus shale and other geologic formations, according to the Department of Energy’s (DOE) National Energy Technology Laboratory (NETL).

ABSMaterial’s Osorb technology, which uses swelling glass to remove impurities, has been shown to clean flow back water and produced water from hydraulically fractured oil and gas wells. Produced waters are by far the largest volume byproduct associated with oil and gas exploration and production. Approximately 21 billion barrels of produced water, containing a wide variety of hydrocarbons and other chemicals, are generated each year in the United States from nearly one million wells.
