Útdráttur: A new conceptual model for the Mahanagdong sector of the Greater Tongonan geothermal field is presented. Such a revision was partly based on the information from the latest wells drilled in the area, MG-1RD and MG-8D. The conceptual model was then translated into a three-dimensional numerical model for simulation purposes. The simulation code TOUGH was used to run the model until a near steady state condition was achieved. The model was able to duplicate the probable hydrological flow in the system. Likewise, the simulated temperatures and pressures in the wells reasonably matched the measured ones. The horizontal permeabilities were estimated to range between 0.01 - 5 mD while the vertical permeabilities range from 0.01 - 8 mD. The natural recharge is estimated to be 20 kg/s. The model, in order to be useful for exploitation simulation runs, has to be calibrated further against ample production data.
