Composition of Deep Groundwaters Problems and Solutions for the Operation of Geothermal Installations

Abstract

The composition of (thermal) deep water, unadapted pumping conditions and pumping equipment, i.e. inapplicable pipes and treatment facilities, are responsible for various problems according to the exploitation of deepwater resources for balneological and geothermal applications. To guarantee the success of a long-term exploitation of a geothermal drilling a fundamental knowledge of the system enclosing chemical and physical interactions is of particular importance. Besides the for a sustainable utilization mandatory parameters such as temperature, pH-value, redox-conditions, chloride and sulphide contents, also parameters like gas content, microbiological conditions as well as the evaluation of the geothermal processes and the examination of the vulnerability of the resource by using isotope-physical investigations play an important role
