| Abstract | Indonesia has around 29.2 GWe of potential geothermal energy distributed in 276 locations along the volcanic belt running from Maluku to Sumatera. Most of the geothermal concessions are at the development phase hence drilling activities are expected to commence in the near future. In line with this, infrastructure preparation has to commence at the soonest possible time. Geothermal developers in Indonesia have to cope with some hurdles and obstacles regarding soil works in this infrastructure preparation phase. Geotechnical hurdles can happen any time and may have serious ramifications on the geothermal exploration and development activities In order to address this matter, site assessment can be implemented prior to site selection. The data gathered during site assessment can help the developers choose the best strategy for designing the infrastructure. Site selection has to be consistent with the initial development plan on which the permit was based. Lack of information regarding the geothermal project site could lead to problems. Hence data gathering should be undertaken in the early stages of the project. Mitigation of the risks should be considered as a part of the geothermal development. Information about the site candidates correspond with the steam source information will significantly reduce the risks resulting from geotechnical hurdles. |
