Abstract
Development of deep geothermal resources exceeding 300?C has become very important in many geothermal fields. To adequately describe the entire picture of a total fluid circulation which is very important to understand the nature of such deep high-temperature geothermal resources, we have developed a numerical simulator capable of simulating geothermal reservoirs which may contain super-critical fluid, up to and 1000 bars. To overcome computational problems associated with rapid changes in fluid properties around and within a certain region above the critical point, we employed interpolation in the vicinity of the region. Using this simulator, we demonstrate that we are able to model deep hydrothermal convection systems.
