Table 4B shows values of permeability, porosity, formation resistivity factor, shale (clay) fraction, and resistivity Ro of eight zones of a shaley (clayey) formation. The resistivity of shale is 4 ohm-m and the formation water resistivity is 0.1 ohm-m. (a) Estimate the water saturation in each zone using (1) the generalized shale relationship, and (2) Hilchie's approximate shale relationship, and compare the results
