WebThere are two types of deviation from Newton's law that are observed in real systems. The most common deviation is shear thinning behavior, where the viscosity of the system … WebThe shear-thickening behavior of the polymers has a negative effect on the injectivity of the fluid. Since the flow rate is high near the injection and production wells, the injection pressure might become more than that of formation parting pressure. This leads to fracturing the reservoir rock.
