Call for papers: Tracers in Deep Geothermal Systems

Geothermal Energy welcomes submissions to the new article collection 'Tracers in Deep Geothermal Systems'.

Exploitation of deep geothermal energy can greatly reduce greenhouse gas emissions associated with heat and electricity generation. Development of new geothermal reservoirs (including heat storage), however, depends on creating, or finding, flow systems that can provide sustained heat exchange. The needed characterization of the underground is often difficult because of the high cost of drilling and reservoir engineering. In typical settings, physical access to the flow path topology is constrained to the few boreholes required for production and injection. Hydraulic tests and geophysical investigations are useful but provide only poor information about heat exchange characteristics. In addition, hydro-thermal-chemical interactions may alter flow paths over time, so characterization may need periodic updates. Improved characterization capabilities are thus critical for increasing geothermal energy use.
This special issue addresses tracer investigations in  geothermal systems to characterize the critical properties of geothermal reservoirs. Contributions may address new tracers or tracer test methods, and may involve single-well to multi-well tests with conservative and reactive tracers, novel tracer substances - like temperature tracing compounds and particle tracers – and environmental tracers. As tracer tests in such settings sometimes produce "strange" results and may even fail because the hydrogeological setting differs from expectations, papers addressing the reasons for anomalous results are equally welcome. Contributions utilizing chemical composition and isotope signatures to describe regional flow paths and influx from overlying and underlying strata are also sought to complement the inter-well tracer tests.

Submission may include but are not restricted to the following  topics: 

  • Single-well tracer tests
  • multi-well-tracer-tests
  • thermal tracers
  • isotope tracers
  • thermal breakthrough
  • heat exchange in reservoirs
