Lucia's carbonate classification was selected to be used in this research. Electrical end effects were minimized by utilizing a four-electrode system. An oil/ water system and a gas/ water system have been studied. The effects of vugularity on the petrophysical properties were evident from the experiments. For a constant porosity, as vugularity increases, cementation exponent (m) and saturation exponent (n) increase systematically. The irreducible water saturation, the capillary pressure curves and the displacement behaviors are also substantially different from homogeneous sandstone experiments.
