Swan Hills ISCG/Sagitawah Power Project

In Situ Coal Gasification Facility

The ISCG Facility includes the ISCG well pairs and associated pipelines, and the syngas processing plant. The ISCG Facility uses independent pairs of wells to gasify coal in its original coal seam to provide raw synthesis gas (or syngas) to a surface gas processing plant. At the syngas processing plant, the syngas is cleaned to remove impurities. The plant takes advantage of the syngas high pressure and high CO₂ concentration conditions to remove the CO₂ stream in a cost-effective manner.

The ISCG Facility is situated near Swan Hills, Alberta, adjacent to established oilfields with over 4 billion barrels of original oil in place, providing compelling opportunities for CO₂ sales to EOR customers.

Environmental aspects

There are a number of key environmental aspects associated with ISCG and the ISCG Facility that make this process an environmentally responsible way to produce clean energy from Alberta’s deep coal resource:

• No fresh water use: The ISCG Facility utilizes saline water in the gasification process, eliminating the injection of fresh water into the subsurface.
• No mining of coal: The ISCG process does not involve a coal mine or any solids materials handling, greatly reducing surface land disturbance and producing a very compact energy facility land use footprint.
