Ulumbu is a geothermal field located in East Nusa Tenggara, which has been generating electricity of 10 MW. To accommodate a better understanding of the geothermal system characteristics and the unexplored area of the prospect, it is important to perform reservoir modeling study. A completely improved natural state model of Ulumbu geothermal field is discussed in this paper. The newer model consists of several improvements in terms of model structure and model validation. The improved natural state model can represent more accurate modeling results and can overcome the limitations of the previous version.
