Technology Innovations for Energy Services

After secondary recovery attempts like waterfloods fail, TIORCO offers an alternative that promises to maximize your production, BrightWater® technology for waterflood sweep improvement. Co-developed by Nalco, BP and Chevron, this unique chemistry is injected downhole with flood water during a secondary recovery process. It is designed to activate at a pre-determined “in-depth” location within the reservoir. Upon activation, the BrightWater particles begin to expand to many times their original volume, blocking pore throats and directing injection water into untapped, oil-rich zones. This deep reservoir profile modification causes additional oil to be swept toward the producing wells.
