Abstract
Process for the detection of heterogeneities of a medium. It is defined in that logs of the attenuation of the shear waves and STONELEY waves are produced, the variations of each attenuation log in relation to a mean value are determined, and then the variations are compared with one another in such a manner as to determine the nature of the heterogeneity or of the petrophysical characteristic which has produced these variations. Application in particular in the area of oil and more particularly in the exploration of a medium. FIG. 9.
