Subsurface Geophysical Characterization of the Crystalline Canadian Shield in Northeastern Alberta: Implications for Geothermal Development

  • Author / Creator
    Chan, Judith S.
  • In northern Alberta, existing heat flow and geothermal gradient studies suggest that using geothermal heat in oil sands processing would require deep drilling of the crystalline Canadian Shield. Using a 2.36 km deep borehole located near Fort McMurray, the goal of this study is to investigate the presence of any geological features that could act as fluid pathways for the development of an engineered geothermal system in the basement rocks. This is done by integrating the results from a comprehensive suite of geophysical borehole logs, seismic reflection surveys, zero-offset and walk-away vertical seismic profiles. The final results provide useful information on the in-situ physical properties of the rocks, depths to fracture zones and seismic reflectors, types of fractures, stress directions, and the acoustic responses of rock properties. Significant P-wave velocity anisotropy is also observed from the walk-away vertical seismic profile.
