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… Expand

Optimal polymer slugs injection curves
TLDR
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. Expand

TLDR
These algorithms are tailored to real field applications thanks to their advanced features: handling of general complex geometries, robustness in the presence of rough tensor coefficients, low sensitivity to mesh orientation in advection dominated scenarios, and provable convergence with fully unstructured grids.
