ABSTRACT
We propose an equation and boundary conditions characterizing flow of viscoelastic fluids in pores of a rock. The equation was discretized by a finite-difference method. We obtained the velocity contour for different boundary layers. We found that a more pronounced boundary layer effect leads to a slower flow velocity in the pore and a smaller micro sweep area, while the area occupied by residual oil becomes larger and the sweep efficiency is reduced.

    Synovial fluid is a polymeric liquid which generally behaves as a viscoelastic fluid due to the presence of hyaluronan molecules. We restrict ourselves to the regime in which the fluid responds as a viscous fluid. A novel generalized power-law fluid model is developed wherein the power-law...
