Damage characterization of deep bed filtration

Abstract

During water injection, solid and liquid particles dispersed in the injected water are trapped by the porous medium and may increase hydraulic resistance to flow. The full-length paper presents a mathematic model for deep bed filtration that contains filtration and formation-damage coefficients, λ and β. These parameters should be determined from laboratory coreflood tests. A new method to determine both coefficients is developed. The proposed method furnishes unique values for the two empirical coefficients.
