Energy decarbonization and energy storage are key elements in the world's energy future. In Canada, the coldx000D
climate means that a great need for reliable heat and electrical power exists. In the North, diesel fuel, importedx000D
at great cost, generates all heat and power. Indigenous communities depend on this costly, carbon-rich sourcex000D
that is also a fire hazard and potential pollutant. Geothermal energy in deep rock masses promises to providex000D
heat and power to remote communities, enhancing their life quality and opening new possibilities forx000D
community activities.x000D
Deep in the earth, the rock is hot enough to extract beneficial energy. In low permeability rock, this requiresx000D
several boreholes, carefully placed through directional drilling, and connected through hydraulic fracturing.x000D
New drilling techniques are emerging for deep hard rock - hammer drilling with reverse circulation. Afterx000D
fracturing to establish communication between optimally placed well pairs, fluid circulates through the rockx000D
mass to bring heat to the surface, used for power and heating.x000D
Dr. Dusseault will work with Scientific Drilling International (Canada) Inc. to advance technologies forx000D
directional drilling of deep geothermal boreholes in hard rock (low porosity sedimentary rocks, igneous rocks).x000D
Assessment of directional drilling methodologies with hammer drilling methods is a basis of study, as well asx000D
evaluation of geothermal efficiency potential for different well placements, needed to decide on the best wellx000D
placement strategies. Well designs and various monitoring approaches will be examined for these issues, withx000D
the goal of reducing drilling costs and making geothermal energy more accessible for northern Canadian
