It is the purpose of this paper to present the results of experimental studies and discuss about the effects of clays and clay minerals upon relative permeability curves. The relative permeability measurements were carried out on artificial and natural samples. And then, Size Analysis, Differential Thermal Analysis and Spectral Analysis were conducted on an oil sand core in order to examine the clays and clay minerals.
