“…The surrounding boundary is defined as boundaries 1 and 2, which are set to be impermeable layers. The numerical simulation result has been confirmed to be reaching its natural state by comparing the subsurface temperature from the simulation result to subsurface temperature estimation using an approach from Saputra [35] at the corresponding depth. The calculation result shows the estimated temperature beneath the Gedongsongo fumarole is 176 o C at elevation 115 mbsl and compared with the temperature at the same position and depth in the model, which temperature is 168 o C has an 8 o C deviation.…”

A careful decision needs a comprehensive and effective way to estimate the subsurface condition and the possible resource contained in the geothermal system. Numerical model and simulation sum up the result of geoscience study and its correlation to the behavior of the subsurface fluid flows. A well-developed numerical simulation could give a thorough analysis of a geothermal system and be utilized as input parameters to apply the resource assessment method. This study applied the numerical simulation to the Ungaran geothermal field using TOUGH2 reservoir simulation software. Several parameters were referring to these simulation results and used as the input parameters to the resource assessment method using Monte Carlo simulation. The result shows that the resource value with the highest confidence is lower than the earlier resource estimation of the Ungaran Geothermal System, which is only based on geoscience study. This study gives a careful analysis to support decision-making, especially in a geothermal green field.

“…There are about 70 lithology units on this map, but this unit will be simplified by coloring based on rock sources to aid modeling. Subsurface temperature distribution, other than based on the well data, is obtained from the results of temperature estimation given by Saputra (2006) [1]. By this method, the subsurface temperature of the conductive layers can be determined.…”

The Blawan-Ijen is one of the geothermal prospects in the eastern part of Java island, Indonesia. This prospect is situated in the caldera called the Kendeng caldera. The Blawan-Ijen has geothermal manifestations in two different locations, the Ijen crater in the southeast and Blawan in the northern part of the caldera. These manifestations are estimated to have different reservoirs. Different manifestations of characteristic and lithological complexity in the Kendeng caldera make the geothermal system contained in the caldera less known. Therefore, a 3D model was built on understanding the geometries of the Blawan-Ijen geothermal system. In this research, the model is limited to the geological and isothermal model. The data used in building the models are based on the literature and research data that has been done previously. Geological and isothermal models were built using Leapfrog Geothermal software. The 3D conceptual model provides a general overview of the geometries of the Blawan-Ijen geothermal system. The isothermal model shows temperature anomalies and their possible distribution.
