Abstract
Geothermal energy resources, as well as other types of renewable energy sources, are able to satisfy almost any consumer in terms of its potential and quality of its energy. The application and the use of geothermal waters of any deposit depends on the energy potential, the chemical composition, the mineralisation and aggressiveness of the water, the general stock and flow rate of wells, the availability and distance of the potential consumer, the temperature and hydraulic modes of boreholes, the depth of occurrence of aquifers and their characteristics, and much more. This feature is one of the main differences of geothermal energy from other renewable energy sources. The exploration of geothermal groundwater was carried out at the Zharkent basin site, in order to assess the operational reserves of thermal groundwaters. There are several wells on the territory of the Zharkent geothermal deposit that can be used as an energy source. Thus two promising geothermal wells, №1RT and №3T, were identified during the exploration, according to which the studies were carried out.
