| Abstract | The data available for the Milos geothermal field are a detailed geothermal gradient map obtained by measurementsin shallow bores and measurementsin the five deep wells which partially penetrate the reservoir. These are mainly temperatures and pressures profiles down the wells, measurements at the well head and chemical composition of the fluid. Little is known about the reservoir itself. The aim of this study was to evaluate the reservoir properties and predict its behaviour under exploitation. The initial state of Milos field was modelled using the MULKOM simulator. Several credible two dimensional axisymetric models were set up covering an area with a radius of 20 km. Later they were expanded to three dimensions and were calibrated so that the temperature gradients near the surfaceand the measured reservoir pressures and temperatures were matched. The was proved to be of low vertical permeability and the reservoir thickness was evaluated at around 1200 m. The heat flow into the field was estimated at about 120 MW while the total induced circulation through the systemwas about 50 Finally the behaviour of the field under exploitation was simulated for different production scenarios. |
