Abstract

A VSP test experiment at the high temperature geothermal field Krafla in Iceland has been carried out. In two boreholes a zero-, far- and moving-source VSP has been applied to delineate subsurface fracture sets, zones of supercritical fluids, superheated steam and zones of magma with the background of a magmatic, high temperature and high attenuating basement. A careful preparation and evaluation of the survey is needed in order to provide a high resolution image of the surrounding subsurface. Under such special conditions high-quality three component data have been recorded and will grant a good basis for further processing and imaging techniques. It can be assumed that VSP techniques will provide a good alternative and addition to hitherto only applied surface seismic, teleseismic or microseismic procedures.
