Abstract
- Sedimentary basins are suitable to different degrees for CO<subscript>2</subscript> geological sequestration as a result of various intrinsic and extrinsic characteristics, of which the geothermal regime is one of the most important. Warm basins are less favorable for CO<subscript>2</subscript> sequestration than cold basins because of reduced capacity in terms of CO<subscript>2</subscript> mass, and because of higher CO<subscript>2</subscript> buoyancy, which drives the upward CO<subscript>2</subscript> migration. A set of 15 criteria, with several classes each, has been developed for the assessment and ranking of sedimentary basins in terms of their suitability for CO<subscript>2</subscript> sequestration. Using a parametric normalization procedure, a basin's individual scores are summed to a total score using weights that express the relative importance of different criteria. The total score is ranked to determine the most suitable basin or region thereof for the geological sequestration of CO<subscript>2</subscript>. The method is extremely flexible in that it allows changes in the functions that express the importance of various classes for any given criterion, and in the weights that express the relative importance of various criteria. Examples of application are given for Canada's case and for the Alberta basin in Canada. [ABSTRACT FROM AUTHOR]
