AbstractThe Winnipeg and Deadwood formations form deep clastic reservoirs in Saskatchewan, Canada, with temperatures exceeding 40°C over most of southern Saskatchewan and reaching 100°C in southwestern Saskatchewan. At these temperatures, the formations have
geothermal potential for development of direct use and electricity generation systems. Numerous disposal wells operating at rates of 30L/s or more are currently installed in these formations, suggesting that electricity could be generated at rates exceeding 2 megawatts of electrical output (MWe) from individual wells. These basal clastic units, thus, could provide significant energy supply over a broad region
of Saskatchewan.
Summary(Plain Language Summary, not published)
A study was conducted to assess the potential for heat from deep formation waters in Saskatchewan to form a viable source of geothermal electricity and direct heating. A high level study was conducted based on pre-existing data of formation water temperatures and production rates. The study was focused on the geologic potential of the resources and did not assess the economic potential. Results show that south of 52o latitude the deepest parts of the sedimentary basin host fluids at high enough temperatures and with sufficient production rates to be able to produce direct heat and in some areas electricity.
