Geothermal Feasibility Study — Parisian Basin

JRG Energy supported Rockwater in preparing a feasibility study for integrating geothermal heat into a large-scale industrial application in the Parisian Basin. Work included destocking and reprocessing of legacy 2D seismic data, quick-look reservoir modelling, and geochemistry modelling. Outputs were used to assess project viability and support the conclusions of the feasibility study.
