Claim 3:
4. The analytical method of claim 2, wherein the third well-logging probe measures the shear wave transit time of a zone in the formation of interest, the first well-logging probe measures the compressional wave transit time, and the second well-logging probe measures the density data through the zone, wherein a representation diagram is chosen as a function of the second P- to S-wave velocity ratio and of the second acoustic impedance, wherein the system of sets of pairs of values of the representative parameters, each pair of values associated with a same fluid saturation, may be likened to a set of parallel iso-fluid saturation curves (108), the same fluid saturation associated with each pair of values of the second acoustic impedance and of the second P- to S-wave velocity ratio measured in the at least nearest well being determined by identifying an iso-fluid saturation curve passing through a point representative of a pair of values (109) in the representation diagram.
