This paper presents a statistical study of the geothermal resource risk in Indonesia, specifically, that the resource base and well productivity are adequate and that the drilling cost per well is reasonable. The study relies on the resource base estimates of nearly 80 sites, and productivity data on 215 wells in the country.
