Viscoelastic measurements of four heavy and extra-heavy oil samples were carried out to analyze the dependence of complex viscosity, loss and storage modulus with temperature and frequency. The dynamic rheological tests showed a shear thinning phenomenon typical of nonNewtonian fluids, highly pronounced for seismic and sonic frequencies and for temperatures… CONTINUE READING
