POSSIBLE COLLABORATION

• Construction of 3-D electrical resistivity models
  of the geothermal areas taking into account the
  EM data, prior geological and geophysical info
  and formalized experts experience
• Modeling of MT monitoring of the reservoir
  macro-parameters
• Development of 3-D temperature models of the
  geothermal zones from well records and estimation
  of the correlation with the resistivity
  distribution
