Abstract

Temperature-dependent dielectric and viscosity studies have been carried out in two samples of crude oils procured from different wells of Oman oil fields. The dielectric permittivity is found to decrease linearly with increasing temperature for both samples. The relaxation frequency at which the loss attains peak value decreases with decreasing temperature. The viscosity of both samples is found to have an Arrhenius type of variation, from which activation energy was estimated using the reduced temperature plots. Further, the viscosity data was used to estimate the shear wave velocity and the attenuation parameter of the samples using relevant theories.
