Preliminary Assessment of Deep Geothermal Resources in Trois-Rivieres Area, Quebec

摘要

Previous studies of geothermal potential across Canada (Majorowicz and Grasby, 2010) and Quebec (Minea and Majorowicz, 2011) showed relatively high heat flux and temperatures in the general area of the St. Lawrence Valley against the background of generally low heat flow of the Canadian shield. This paper presents more detailed analysis of temperature-at-depth realtion-ships, geological structure, tops and lithology in the large western part of the St. Lawrence Valley in a region which includes the most populated cities like Montreal, Trois-Rivieres, Quebec City, Rimouski and Sherbrooke. A review of power generation cycles and preliminary estimations of total and specific costs of doublet and triplet Enhanced Geothermal Systems (EGS) feasible for use in the specific geothermal conditions of the studied area are also presented.
