Abstract

The Riza - Antirrio area constitutes a new low enthalpy geothermal field located on the northern side of the Corinthian Gulf in Western Greece. After a detailed and systematic reconnaissance study including evaluation of geological and tectonic setting of the area, geophysical surveys, water temperature measurements at the heads of the existing irrigation and water supply wells, sampling and hydrochemical study, 4 geothermal wells were drilled. The first geothermal exploration borehole was drilled to a depth of 402 m during 1998-99. Two more wells were drilled in the period 2005-2006. Exploration borehole GL-1 was drilled down to 275.5 m and the temperature of 38°C was recorded at 270 m. Production well GLP-1 has a depth of 229 m and it yields 25 kg/s water of 36°C and Na-Cl type with TDS content of 45.7 g/L. The geothermal reservoir of this low enthalpy field composed of Eocene limestones is located at depths of about 110-250 m.
