ABSTRACT:
A method to estimate water saturation (Sw) of a thin-bedded formation is provided including (a) developing a model of anisotropy of resistivity (Rv/Rh) a function of water saturation (Swt) for one or more volume fractions (either Fshaleor Fsand); (b) measuring the anisotropy of resistivity of the formation; (c) measuring the volume fraction of the formation; (d) correlating anisotropy of resistivity to the measured volume fraction of the formation using the model to estimate the water saturation (total water saturation or sand water saturation) of the formation.
