Updating the Conceptual Model of Cisolok-Cisukarame Geothermal field, West Java, Indonesia

Abstract

The cisolok-cisukarame geothermal field is a liquid dominated geothermal system situated in Sukabumi District, West Java, Indonesia. Geothermometry survey shows that Cisolok-Cisukarame has temperature approximately 185-212°C in the reservoir. The temperature of the reservoir shows that this is a medium enthalpy geothermal system. The thermal manifestation distributed around the Cisolok-Cisukarame area when the Cisukarame indicated as the upflow zone and Cisolok as the outflow zone. It is located at the eroded volcanic area with cooling pluton acting as the heat source of the system. Based on EBTKE, Cisolok-Cisukarame geothermal field has 45 MWe possible reserve. NE-SW and N-S faults are acting as the main conduit of the geothermal system. The primary purpose of this study is to build a computer model describing the natural state condition based on the geological, geochemical, geophysical, and well temperature data from several published literature. The model was validated by using mass-heat flow profile obtained from the observation data to achieve the best representation of the actual condition. The condition was achieved by modifying the permeability structures and productivity index. This model is the first natural state model of Cisolok-Cisukarame geothermal field. The natural state model then is used to build an updating conceptual model of Cisolok-Cisukarame by using data from a result of numerical modeling. Based on the parameters obtained from the numerical modeling, a new model of Cisolok-Cisukarame geothermal field is successfully representing the heat and mass flow within the system.

Identification and screening of enzymatic abilities of Ktedonobacteria from forest soil of Cisolok Geothermal Area, Indonesia

“…Cisolok geothermal area is one of the prospecting geothermal areas in Indonesia (Herdianita and Mandradewi 2010) that provides a heat energy source from the volcanic activity below Mount Halimun, West Java (Sumartha et al 2020). Thermal water from geysers along the Cisolok river discharges continuously and extends to the forest alongside the river, thus the forest near the Cisolok geysers was exposed to thermal water discharge (Figure 1).…”
