GE’s SAGD Produced Water Evaporators enable users to perform the enhanced oil-recovery technique known as steam-assisted gravity drainage (SAGD). Falling film evaporators powered by mechanical vapor compression convert produced water and brackish make-up water to boiler feed water. Steam is then generated and injected underground liquefying the heavy oil, which is pumped to the surface.
Environmental Benefits
Compared to the traditional chemical water treatment approach used in once-through steam generators for heavy oil recovery, GE’s SAGD Produced Water Evaporator is designed to reduce total water consumption by approximately 50 percent. GE’s SAGD Produced Water Evaporators also generate less wastewater and use less chemicals than the traditional approach.
Operating Benefits
GE's SAGD Produced Water Evaporator is designed to reduce the volume of wastewater disposal by approximately 90%, saving customers approximately $.14/bbl of oil produced or $10,000/day for a 70,000 barrel per day facility, assuming a deep well injection cost of $2.10/tonne.
