Project Abstract

TOUGHREACT project is a numerical simulation program developed at Lawrence Berkeley National Laboratory (LBNL). The project involved the development of a coupled reactive fluid flow model including various reactions of water phase with basalt so as to mimic Icelandic geochemistry within the TOUGH-REACT software and the development of a new method, GOUST, for fitting model parameters using the iTOUGH inverse modelling software. These tools were applied in studies of CO2 sequestration at Hellisheiði, as well as a model of the Laugarnes low temperature geothermal area. Including mineral alteration and silica scaling in hydrothermal systems under natural and producing conditions, and natural groundwater quality evaluation. TOUGHREACT is based on TOUGH2, a multiphase fluid and heat flow simulator.
