Artificial tracers for geothermal reservoir studiesArtificial tracers for geothermal reservoir studies Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-09-191993enSafe disposal of thermally spent geothermal brines that contain environmentally hazardous constituents is commonly obtained by reinjection. The reinjection process also serves to maintain reservoir pressure, enhance thermal recovery, and eliminate possible compactional subsidence. To avoid premature thermal breakthrough of reinjected fluids, tracer tests are employed for detection and evaluation of preferential path networks. In this paper some promising tracers that have not received much attention in geothermal reservoir studies are discussed, and a comprehensive tabulation of field sites of artificial tracer utilization is presented. Chemical and transport processes responsible for tracer retention by the formation of reservoir solids, as well as available tracer detection techniques, are emphasized.http://creativecommons.org/licenses/by/4.0/Environmental Geology22160-70A9-EG-93.pdfChania [Greece]Library of TUC2015-09-19application/pdf1.4 MBfree Chrysikopoulos Constantinos Χρυσικοπουλος Κωνσταντινος Physicochemical tracer retention processes
