Abstract
Steam roduction in Larderello field is obtained from fractured rocks having a very low matrix permeability.
Fractured zones are irregularly distributed and their location is one of the main objectives of present geophysical research and one of the principal problems in field exploitation. This problem has also been approached from a geological point of view in an attempt at finding the relationship between secondary permeability and the lithological and structural characteristics of the reservoir formations.
The first results, obtained by Cataldi et al. (1963), found a high -- ratio of productive/unproductive wells. along the axes of the positive structures.
The present study of the Kh distribution in Larderello fields should permit a more detailed analysis of the different geological factors affecting the productive capacity of the reservoir formations.
