The previous exploration\ndemonstrated the presence of a fractured carbonate reservoir, mainly belonging to the Cretaceous section of the\nApulian shallow water carbonate platform (e.g. Scrocca 2010 and references therein), which is deformed to shape\na buried antiformal stack. The culmination of the uppermost thrust unit reaches a depth of about 200 m SSL (i.e.\nabout 1100 m below the ground level). The reservoir fluids are made up by a CO2 gas cap, which rests above\nan accumulation of fresh water in the central and upper part of the culmination of the deep carbonatic acquifer\n(e.g., Monte Forcuso 1 and 2 wells), and a saline water along the flank of the buried anticline (e.g., Bonito 1 Dir,\nCiccone 1 wells). Medium enthalpy geothermal resources with a reservoir fluid temperature up to 100C have\nbeen estimated in previous assessments at depth of 2000 m below ground level (ENEL 1987; 1994).\nHowever, the presence of thermal springs (e.g. Terme di S. Teodoro) in the area suggests the presence of an active\nhydraulic circuit and provide further constraints about the geochemical characteristics of the reservoir waters, and\nthe geothermometers investigation (Duchi et al. 1995) give a possible reservoir fluid temperature up to about 124\nC.\nIn this study, the overall reservoir/caprock system structural-stratigraphic setting has been defined based on the\nintegrated interpretation of surface geology, public and available seismic reflection profiles, and composite well\nlogs. In particular, a careful assessment of temperature field at depth has been carried out analyzing the well\nlogs through Horner plot construction (Rider, 1996 and reference therein). Where the temperature data data were\nscarce or poorly constrained, the approach proposed by Della Vedova, et al. (2001) has been applied. On the basis\nof well tests, cores and mud losses/absorptions, the reservoir permeability was also re-estimated, confirming quite\ngood permeability values for the fractured carbonate reservoir.\nOne of the main results of this research is the development of an integrated 3D geological model which provides\nthe base for a detailed assessment of the possible geothermal exploitation of the carbonate reservoir. The\npreliminary results of our analysis suggest that \\\"Guardia dei Lombardi\\\" can be indicated as an interesting area for\nthe geothermal medium enthalpy exploitation, although the presence of the CO2 gas cap and the scaling capability\nof the deep fluids should be carefully evaluated.\nFrom the 3D geological model, we put a sounding basis for a numerical model of hot fluid extraction\n(made by TOUGH/TOUGHREACT) in which some reasonable hypothesis on the reservoir exploitation may be\nevaluated."@en ; prodottidellaricerca:prodottoDi modulo:ID8434 , istituto:CDS042 ; pubblicazioni:autoreCNR unitaDiPersonaleEsterno:ID20456 , unitaDiPersonaleEsterno:ID14854 , unitaDiPersonaleInterno:MATRICOLA5873 , unitaDiPersonaleInterno:MATRICOLA7687 . ns12:ID47821 pubblicazioni:rivistaDi prodotto:ID202168 .
