Regional Groundwater Flow Patterns in the Northern Great Plains Area and their Effect on CO2 Sequestration at Weyburn, Saskatchewan, Canada

Regional groundwater flow patterns in the Northern Great Plains area do not follow the concept proposed by Downey et al. [6] and adopted by Bachu [2,3] for Alberta, and Khan and Rostron [9] for the Weyburn CO2 sequestration site in Saskatchewan. Accordingly, investigations for the migration behaviour of sequestered CO2 in Weyburn and in Alberta should be revisited by applying modern fluid dynamics based on Hubbertʹs [1] force potential instead of the methodology of continuum mechanics. Continuum mechanics had been developed in the 19th century for solving practical engineering problems. These methods are not suited for delineating regional groundwater flow patterns and the effect of groundwater flow on CO2 storage.
