Shear Rate and Permeability in Water Flooding

Abstract: Water breakthrough during oil recovery can be inhibited by the use of novel shear-induced structure additives. These affect the shear rate experienced by fluid inside the rock matrix. We relate this to the permeability for the purpose of applying these novel non-Newtonian materials which thicken viscosity only in the shear range associated with the permeability of the reservoir while maintaining base fluid properties outside this range.

“…The effect of this preferential flow can be evaluated by comparing the velocity in each streak with the velocity in the least permeable layer. This results in a dimensionless factor; the ratio of the flow velocities in zones with high and low permeability u hi and u lo at equal pressure gradient (Reuvers and Golombok 2008):…”

“…Rather, it is necessary to compute a volume-averaged shear rate magnitude, trueγ.¯V, as a function of the local blood speed using an analytical or empirical expression. In the case of the former, a first-order approximation to the shear rate can be derived from a hydraulic radius model, which, for example, in the principal x– direction gives u0Kxx-1/2 [50]. However, this approximation only accounts for viscous forces and neglects the inertial forces that clearly make an important contribution to the flow within the foam (see Fig.…”

“…Jones [84] hypothesized that it is possible to employ shear-thickening characteristics to overcome the challenge of preferential flow, which tends to only flow through the high-permeability zones of reservoirs rather than the low-permeability zones, where trapped oils remain upswept. This hypothesis also led the work of Golombok et al [20,85], who carried out experimental investigations on pressure-driven flows within cylindrical glass core samples with different permeability classes. The shear-thickening response that is caused by an associated flow through the high-permeability zones will result in a higher local fluid viscosity when compared to the viscosity of fluid flowing through the low-permeability zones under the same pressure drop.…”
