ABSTRACT OF THE DISCLOSURE The determination of a "composite" parameter of the formation water in formations surrounding a borehole, for example the composite conductivity of the formation water, is used in the disclosure to obtain a relatively accurate determination of formation characteristics, such as water saturation. The determined values are meaninful even in shaly regions of the formations. The disclosed technique determines a composite water parameter, for example a composite water conductivity, which represents the conductivity of the bulk water in the formations, including both free water and bound water. Bound water trapped in shales is accounted for in this determination so the shales can be considered as having a porosity. Having determined the composite water conductivity, water saturation can be directly obtained using relatively straigthforward relationships which do not require estimates of the volume of shale in the formations. Shale effects are accounted for by the different conductivities (or other parameter such as caputre cross sections) of the formation water constituents (free and bound) which make up the total water.
