A comprehensive study on modeling methods for gauging of resources in a geothermal reservoirs

Resource assessment and reserve estimation plays a critical role in the economic development of the geothermal field. Various methods are available for resource assessment. Most studies of resource assessment highlight the statistical residual value, showing the inaccuracy of the implemented procedure in estimation. These shortcomings are due to various reservoir parameters such as hot fluid volume in place, recharging rate of the natural fluid in the reservoir, economical rate of extraction, and program to develop the field during this beginning stage. The present study discusses the applicability of various geothermal resource estimation methods and compares various methods for assessing geothermal resources. The study brings out different techniques used for resource estimation and also categorizes them in the context of reliable applicability in geothermal resource estimation. Based on the comparative analysis, suitable applications for several methods have been identified.
