The aim of the laboratory experiments presented here is to find a set of thermosensitive tracers to identify thermal characteristics in deep geothermal reservoirs during the long-term operation of a power plant. In the near future several short-term push-pull experiments are planned at different test-sites in northern Europe. As a first step we focus on tracers which fulfill the requirements of...

Background Engineered or enhanced geothermal systems (EGS) have been promoted as a technology that exploits geothermal heat and power production from regions of the crust devoid of shallow high enthalpy reservoirs (also referred to as high-grade hydrothermal resources) (e.g., MIT 2006). The status of EGS development was reviewed by Breede et al. (2013) who reported on 14 EGS projects that were ...

Raw material extraction from geothermal fluids often comprises concentrating and cooling steps, which increases the risk of silica scaling formation. However, existing removal strategies do not consider impact on raw extraction. In this study, applicability element-selectivity three techniques (seed-induced, lime caustic precipitation) were tested in batch experiments using synthetic natural fl...
