It is well known that the fluids have no shear modulus and therefore no shear wave can propagate through fluids. But heavy oils have properties that are much complex than lighter oils. At low temperatures, heavy oils are extremely viscous and begin to act like solids. An effective shear modulus appears allowing propagation of shear waves. The bulk moduli of heavy oils increase since the bulk and shear moduli are related with each other. Therefore, it is observed that the compressional wave velocity of heavy oils increases faster than that of light oils at low temperatures.
