Abstract
In order to simulate the behaviour of a geothermal system for field management purposes, a numerical model is initialised based on conceptual models that capture the initial state of the reservoir, integrating the current knowledge of the system and its dynamics. Geothermal reservoirs are dynamic systems, where continuous fluid and heat flow affects the reservoir chemical and stress equilibria leading to precipitation or dissolution of minerals and changes in the pore geometry over the lifetime of geothermal activity. The speed and intensity of these changes depend on the rock
