Scaling in fractured geothermal carbonate reservoir rocks: An experimental approach
Mineral precipitates along thermal fluid pathways (scaling) and clogging by unconsolidated grains inversely affect the efficiency of geothermal systems. An experimental approach is presented to quantify dissolution-precipitation processes in fractured, geologically complex carbonate rocks of Devonian age. The outcome suggests that the dissolution-precipitation processes must be placed in the context of different fluid properties and pressure conditions between the injection and the production well. A geochemical monitoring program documenting the processes in the carbonate aquifer rocks is presented. Experimental work must be combined with field and modelling approaches to unfold its full strength.
期刊介绍：
Geothermics is an international journal devoted to the research and development of geothermal energy. The International Board of Editors of Geothermics, which comprises specialists in the various aspects of geothermal resources, exploration and development, guarantees the balanced, comprehensive view of scientific and technological developments in this promising energy field.
It promulgates the state of the art and science of geothermal energy, its exploration and exploitation through a regular exchange of information from all parts of the world. The journal publishes articles dealing with the theory, exploration techniques and all aspects of the utilization of geothermal resources. Geothermics serves as the scientific house, or exchange medium, through which the growing community of geothermal specialists can provide and receive information.
