With drought baking the U.S. and water becoming a scarce commodity, it's encouraging to learn that some shale gas operators are recycling more water.
According to this month's issue of The Journal of Petroleum Technology, operators in Pennsylvania became motivated to recycle when municipal waste-water treatment facilities refused to accept the hydraulic fracturing byproduct and trucking it away proved too costly.
Now the Marcellus Shale has become a test bed for innovative water filtration units and other water-saving strategies. For example, professor David Burnett of Texas A&M University has developed a mobile, high-tech water treatment unit that operates well-side for less than the cost of injection disposal and with fewer chemicals.
