Introduction
Specialized in geothermal energy, I do research to characterize resources and to optimize systems. I work with system installers, drillers, designers, operators and manufacturers to maximize profitability, develop expertise and develop products. My fields of activity are resource assessment (high and low temperature), hydro-geological field characterization, drill logging, grouting installation, thermal and hydraulic conductivity testing, sizing heat pump systems and numerical modeling.

The design of ground-coupled heat pump systems requires knowledge of the thermal properties of the subsurface and boreholes. These properties can be measured with in situ thermal response tests (TRT), where a heat transfer fluid flowing in a ground heat exchanger is heated with an electric element and the resulting temperature perturbation is monit...
Article
Flooded underground mines are attractive for groundwater heat pump systems, as the voids created during mining operations enhance the subsurface permeability and storage capacity, which allows the extraction of significant volumes of groundwater without requiring extensive drilling. Heat exchange at a flooded mine is, however, difficult to predict...

Conference Paper
Geothermal district heating systems with deep boreholes (1.5 to 3.0 km) can be an interesting alternative to electric heating systems powered by hydroelectricity. The techno-economic potential of deep borehole heat exchangers and geothermal doublets (with and without reservoir stimulation) was assessed, and the results suggest that the latter insta...
