A New Technology for Waterflood Sweep Improvement
BrightWater has been 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.
Over time, production begins to improve. With a simple treatment, you stand to recover up to an additional 5 percent of the original oil in place. This literally translates to millions of dollars in value being added to your asset.
Various grades of BrightWater chemistry have been designed to target injection water thief zones at a range of reservoir temperatures and salinities. The latest generation of BrightWater currently tested for some North Sea fields will expand and set at less than 30°C. At this temperature, the technology promises to not only improve sweep efficiency, but also to minimize the volume of chemical plug required.
