A revolutionary way to treat saltwater. Breathe easier with an environmental approach to saltwater treatment. We developed the WaterWolf™ Dynamic Oil Recovery (DOR) System as a fresh approach to conventional produced saltwater treatment alternatives. With its small footprint, ease of installation and maintenance, and the complete elimination of expensive water treatment chemicals, you can reclaim more oil than ever before. It's time to look at produced water differently. Learn more at nov.com/waterwolf Or call us at 713-335-6600 © 2014 National Oilwell Varco All Rights Reserved D392006063-MKT-002 Rev 01
