Knowledge of the physicochemical (thermodynamic) properties of natural fluids is an essential basis to understand rock–water interaction and all its applications.
From direct observations and fluid inclusion studies we know that geofluids span a wide range of chemical compositions. Moreover, depending on the geological environment in which they occur, geofluids may be active at temperatures up to 1000 °C and at pressures up to several gigapascals. The extreme range of compositions, temperatures and pressures poses an enormous task for quantitative prediction of their properties.
We contribute to the existing knowledge base by measuring thermodynamic properties and by developing theoretical predictive models for geofluids relevant to our applied research projects.
