The paper investigates the linear growth of the mixing zone during polymer slug injection into a water reservoir. The velocities of the slug front and of the boundaries of the mixing zone are analyzed as key parameters. Using two different numerical methods (finite volumes and finite elements), the impact of the slug size, reservoir dimensions, Peclet number, and viscosity curve shape on the corresponding velocities is examined. Notwithstanding the realization of the solution by two… 

Figures and Tables from this paper

Optimal polymer slugs injection profiles

The graded viscosity banks technology (tapering) for polymer flooding is studied for several different models of mixing zones behavior and the limiting polymer injection profile is rigorously derived in case of transverse flow equilibrium assumption.

Optimal polymer slugs injection curves

Based on several one-dimensional approximate models, rigorous formulation of the graded viscosity banks (GVB) technology is given which helps to save polymer by injecting several slugs with gradual decrease of Viscosity instead of one slug.

We investigate the growth of a mixing zone in the displacement of oil by a solvent. Such a zone usually takes the form of long thin fingers of solvent which protrude into the oil. However, despite

Miscible porous media displacements in the quarter five-spot configuration. Part 2. Effect of heterogeneities

Direct numerical simulations are employed to investigate the coupling between the viscous fingering instability and permeability heterogeneities for miscible displacements in quarter five-spot flows.

Miscible flow through porous media

This thesis is concerned with the modelling of miscible fluid flow through porous media, with the intended application being the displacement of oil from a reservoir by a solvent with which the oil

On the selection principle for viscous fingering in porous media

Viscous fingering in porous media at large Péclet numbers is subject to an unsolved selection problem, not unlike the Saffman–Taylor problem. The mixing zone predicted by the entropy solution is

The displacement of one fluid by another (miscible or immiscible) in porous media is an important phenomenon that occurs in groundwater movement and oil reservoir engineering. Practical examples are

We examine the full ‘life cycle’ of miscible viscous fingering from onset to shutdown with the aid of high-resolution numerical simulations. We study the injection of one fluid into a planar
