Renewability of Geothermal Resources

Coordinator at ÍSOR:  Guðni Axelsson

The purpose of the project proposed here is to develop methods to study the recharge and mass balance and apply them to the Reykjanes-Svartsengi geothermal region in Iceland. The proposed project aims to join together the results of several different scientific methods or disciplines to address the issue in question, in particular:

  1. high-resolution 3-D surface deformation monitoring (InSAR and GPS monitoring)
  2. micro-gravity monitoring
  3. repeated TEM resistivity surveying
  4. reservoir pressure- and temperature monitoring
  5. chemical content monitoring and
  6. dynamic geothermal reservoir modelling

Combining surface elevation and gravity data has been used to estimate the mass balance of geothermal systems during production, resistivity surveying has been used for exploration and chemical data has been used to study processes in geothermal systems and their recharge. Detailed numerical modelling of geothermal systems has also been used extensively to simulate the response of geothermal reservoirs to production. The innovative aspect of this proposal involves joining together the results of the different methods through unified modelling of aspects (1) through (5).
