Top mesozoic carbonates depth map of Sicily (Italy)

In the frame of the VIGOR Project, aimed at assessing geothermal potential in four regions of southern Italy (Calabria, Campania, Apulia, Sicily), multidisciplinary data have been used for supporting the reconstruction of the geometry of the main geological units at regional scale, a fundamental prerequisite for computing the thermal model and then the regional geothermal potential. We present the study of all existing geophysical log information combined with the interpretation of available hydro-geochemical data of the Sicily Region allowing us to locate the regional geothermal reservoir within the Mesozoic limestones and dolostones. An integrated review of existing geological and geophysical data (mainly acquired during oil exploration), and the combination with new data acquired in particular key areas, was used for the 3D reconstruction of the top these units. The 3D reconstruction of the carbonate reservoir top from different geophysical methods and well data is a complex task because of: a) the different resolution, area extent, type of survey and relative modeling (1D, 2D or 3D) of each one of the several datasets; b) the areal distribution of geological data and wells and their specific depth; c) the complex geological environment; d) the local absence of data at depth; e) the several different interpretations and geological models existing in the literature. Despite these difficulties a map of the top of carbonate mesozoic units has been tentatively built up for the region. This map could be used as input for the thermal modeling and for the evaluation of geothermal potential. The three-dimensional geological modeling was carried out using "PETREL" software (Schlumberger).
