What is Saturation Exponent at Various Wetting Condition: Fractal Modeling of Thin-sections about?

Saturation exponents, along with resistivity log data, are usually needed for evaluating the initial saturation of a hydrocarbon reservoir. A number of experimental investigations have shown that reservoir wettability affects the exponent value. A remarkable divergence of conclusions, however, still appears in the literature. This paper presents the results of a study based on the application of fractal concepts. The concepts have been used to derive parameters such as clay content and electrical tortuosity of thin-sections at a given wetting condition and for various water saturations. A general equation of electrical resistivity was then developed, incorporating these parameters. The advantage of this approach is that, it is independent of rock-fluid equilibrium problems that commonly influence laboratory measurements. The present work employed 20 thin-sections of limestone and sandstone. It was found that the lowest exponent of 1.8 was obtained for strongly water-wet shaley sandstone and the highest value of 5.3 was for strongly oil-wet conditions. The exponent consistently increases as the wetting condition is shifted from strongly water-wet toward oil-wet. It is close to 2.0 f
