Geothermal Resource Types and their Definitions
来源:地大热能 2016-05-16

In reporting a project in development to the GEA, the developer of a geothermal resource is asked to indicate which of the following definitions the project falls under: Conventional Hydrothermal (Unproduced Resource): the development of a geothermal resource where levels of geothermal reservoir temperature and reservoir flow capacity are naturally sufficient to produce electricity and where development of the geothermal reservoir has not previously occurred to the extent that it supported the operation of geothermal power plant(s). Such a project will be labeled as “CH Unproduced” in this report. Conventional Hydrothermal (Produced Resource): the development of a geothermal resource where levels of geothermal reservoir temperature and reservoir flow capacity are naturally sufficient to produce electricity and where development of the geothermal reservoir has previously occurred to the extent that it currently supports or has supported the operation of geothermal power plant(s). Such a project will be labeled as “CH Produced” in this report. Conventional Hydrothermal Expansion: the expansion of an existing geothermal power plant and its associated drilled area so as to increase the level of power that the power plant produces. Such a project will be labeled as “CH Expansion” in this report. Geothermal Energy Association 4 Geothermal Energy and Hydrocarbon Coproduction: the utilization of produced fluids resulting from oil and/or gas-field development for the production of geothermal power. Such a project will be labeled as “Coproduction” in this report. Geopressured Systems: the utilization of kinetic energy, hydrothermal energy, and energy produced from the associated gas resulting from geopressured gas development to produce geothermal electricity. Such projects will be labeled as “Geopressure” in this report. Enhanced Geothermal Systems: the development of a geothermal system where the natural flow capacity of the system is not sufficient to support adequate power production but where hydraulic fracturing of the system can allow production at a commercial level. Such a project will be labeled as “EGS” in this report.
