Plugging of fracture porosity from mineral precipitation due to injecting cold water into a a geothermal reservoir can impact the overall permeability of the fracture network in the reservoir. This can have serious ramifications on the efficiency of the geothermal resource. Geochemical modeling can be useful in providing a first-hand evaluation of potential of mineral precipitation along the different reaction paths. We developed geochemical models for injecting four different relevant water compositions in the FORGE Utah geothermal reservoir through well 58-32. Results and discussions related to this work are presented in this technical report.
