... with both the salinity and the formation. The depolarization factor (L) in the HB method was found to vary between 0.167 and 0.566 with the average of all the tested samples being 0.371. TPO and CRI were found to predict similar porosities when the water resistivity was greater than 0.3 Q-M. It is...

... constituent materials, and contains an exponent which is dependent upon the shape of the inclusions in the medium being measured. This exponent is known as the depolarization factor and is con- sidered to be independent of the frequency of the electric field used in measuring the dielectric constant. Sen2 has...
