Waterless Fracking? Research at UT

National Energy Technology Lab study at the University of Texas is looking at the best ways to stabilize foams for fracking with carbon dioxide, nitrogen or gas liquids.

Several companies are field-testing new technologies that use high-pressure carbon dioxide, propane or butane instead of water.

 Some argue these new technologies are costly; and others say its the answer to economic and environmental issues related to fracking.  Shale Plays Media | Eagle Ford Texas
