Útdráttur: The results of the interpretation of 50 resistivity soundings carried out in the Berlín geothermal field delineate an extensive geothermal field of 12 km2 at 250 m below sea level. The field is characterized by a low-resistivity cap which is underlain by a high-resistivity core where temperatures exceed 230°C, providing there is an equilibrium between temperature and alteration. The upflow zone is within the caldera close to well TR-5. This is supported by the highest measured temperatures and highest elevation of the high-resistivity core. The existence of a high-resistivity core suggests a fresh water system in the uppermost part of the reservoir, or at least at the depths where resistivity data is dependable.
