A study of Songa-Wayaua geothermal field using TOUGH2 reservoir simulation was conducted. This study shows the workflow to update the Songa-Wayaua conceptual model based on geosciences data, and to assess its potential resource. Since this field still a green field, the model still has so many uncertainties because lack of the actual well data. The numerical simulation of Songa-Wayaua geothermal field has been developed and it showed a proper alignment with geosciences data but still requires validation from well data. This is the first numerical model of Songa-Wayaua geothermal field. The model provides additional insights which have been used to review and update the conceptual model. The conceptual model of Songa-Wayaua geothermal field has been successfully updated. The main updated points of the conceptual model were the location of the heat source to be beneath the Mt. Pele, adding the flow fluid pattern as outflow and upflow location, and adding iso-temperature distribution. By using the heat stored method with probabilistic approach (Monte Carlo Simulation), the resource calculation approximately 30 MWe.
