Útdráttur: The report describes distributed parameter models of two geothermal reservoirs. The basic equations of the problem are derived and the reservoir behaviour of two different geothermal fields is analyzed. The first field evaluated is the Laugarnes geothermal field in Reykjavik, SW-Iceland. In this case the calibration of the model was made on the basis of 30 years observation of the reservoir response to production. A good fit was achieved with the model for drawdown. For the calibration of the model, the measured monthly average production of 16 wells from 1961 to 1991 was used. The obtained reservoir parameters were used for the future prediction of the reservoir behaviour at different constant production rates until the year 2012. A constant decline of the water level and silica content is observed. Based on the trend of the curve for the measured and calculated drawdown obtained from the distributed groundwater flow model, it is quite obvious that with present production, no steady-state condition in the reservoir will be reached during the period ...
