Case Study

Forced Circulation Steam Generators for SAGD Applications

Steam-Assisted Gravity Drainage, better known as SAGD, is considered to be the most viable and environmentally safe recovery technology for extracting heavy oil and bitumen. The process, which has been utilized for more than a decade, uses an advanced form of steam stimulation to extract oil from a pair of horizontal wells drilled into a reservoir.
