  • The target of this study is to correlate the logging data with the lithological and structural characteristics of the drilled volcanic sequences; in particular to extract information which are important to better understand alteration processes as well as the hydrogeological and hydrogeochemical situation. The specific targets of this study are: core-log comparisons and detailed reconstruction of the lithological profile with individual lithological units , evaluation of the BHTV data with regard to stereoscopic analysis of structural elements, calculation of porosity profiles using resistivity and sonic logs, determination of variations of petrophysical in-situ parameter with depth(increasing age); in particular mapping the distribution and extent of alteration and possible fluid path way zones. All log analysis will be closely correlated with petrographical and geochemical core analysis.
