Project goals

Development of electricity production from the geothermal reservoir in Reykjanes. Prior to the power generation commence in 2006 ÍSOR conducted an extensive geothermal exploration in the area.  Geological, geochemical and geophysical data collected on the site were used to construct a conceptual model of the geothermal system. Some 30 wells have been drilled in the area and the power plant in Reykjanes is now producing 100 MWe.

ÍSOR services

ÍSOR, and its predecessor National Energy Authority (NEA), have worked on an extensive geothermal exploration of the geothermal area in Reykjanes. ÍSOR has provided wide range of research and consultancy related to the utilization of the geothermal reservoir, including:

  • volumetric assessment
  • numerical modelling
  • conceptual modelling
  • siting of all wells
  • well testing
  • drilling consultancy and monitoring of the drilling itself
  • well logging
  • reservoir monitoring
  • geochemical exploration
  • geochemical monitoring
  • TEM and MT soundings
  • gravimetric measurement and monitoring
  • environmental monitoring
  • geological mapping
