Iceland GeoSurvey scientists winners of the IGA Best Paper Award 2014

The geoscientists Gudni Axelsson, Knútur Árnason and Gylfi Páll Hersir from Iceland GeoSurvey, ÍSOR, and Hjálmar Eysteinsson from Reykjavik Geothermal, have received the  IGA Best Paper Award for 2014.

The International Geothermal Association (IGA) has in order to promote research and publication in the field of geothermal energy established this Best Paper Award to recognize authors of papers published in internationally peer-reviewed scientific journals annually.

Gudni Axelsson‘s  paper:

Gudni Axelsson, 2010. Sustainable geothermal utilization – Case histories; definitions; research issues and modelling. Geothermics 39, 283–291. The whole article: http://www.sciencedirect.com/science/article/pii/S0375650510000404

From the IGA webpage: Sustainability is a key issue in judging the potential contribution of geothermal resources to mitigation of climate change. This paper provides definition of sustainable production of geothermal fields and theoretical analysis that is supported by numerical modeling of different types of geothermal fields from various geological settings around the world. The paper identifies the research issues in understanding sustainability of geothermal fields. It suggests that thermal balance of a production field can be achieved at the 100-300 year time scale. It also demonstrates through modeling that the effect of heavy abstraction is often reversible on a time-scale comparable to the period of utilization.

Knútur Árnason, Hjálmar Eysteinsson and Gylfi Páll Hersir‘s paper:

Árnason, K., Eysteinsson, H., and Hersir, G.P., 2010: Joint 1D inversion of TEM and MT data and 3D inversion of MT data in the Hengill area, SW Iceland. Geothermics, 39, 13–34. The whole article: http://www.sciencedirect.com/science/article/pii/S0375650510000039

From the IGA webpage: Resistivity survey is an essential part of geothermal exploration. This paper provides new approaches to the application of resistivity surveys in geothermal exploration with emphasis on the interpretation through inversion modeling of the data collected through 1D and 3D TEM and MT. Using a well-studied geothermal field in Iceland as an example, it also shows the strength of such resistivity surveys with particular reference to joint interpretation with other geophysical data.

The International Geothermal Association (IGA), founded in 1988, is a scientific, educational and cultural organization established to operate worldwide. It has more than 5,200 members in over 65 countries. The IGA is a non-political, non-profit, non-governmental organization.
