... clearly that the filtration coefficient increases with decreasing flowrate. The results indicate that formation damage near a wellbore during water injection will be reduced by the presence of residual oil, and that particles will penetrate deeper into the formation. The result is also relevant...

... of a study on formation damage, different concentrations of hematite particles suspended in water were injected into sandstone core samples at residual saturation. The theories of deep bed filtration are evaluated. The effects of residual oil on the filtration coefficient λ and the formation damage factor...

... of magnitude as those obtained from laboratory tests 4 – 11 , 14 , 19 . The values of filtration coefficient also vary inside the regular interval (20–200 m −1 for solid particles and 5–50 m −1 for liquid particles). Nevertheless, the filtration coefficients as obtained for wells SH_A36_2, N1, N2, Gulf...

... particles filtrate independently; the delay term and filtration coefficient for each population are particle size-dependent. The penetration depth for particles with any intermediate size equals the inverse to filtration coefficient times velocity reduction factor α . The average concentration models...

... deposition is commonly referred to as the filtration coefficient. The filtration coefficient is a dynamic quantity and changes with the number of previously deposited particles. Many investigators have carried out extensive theoretical and experimental work aimed at determining the filtration coefficient...

... . The results are very close to the experimental data. Internal Filtration Parameters Two parameters, the filtration coefficient ( λ ) and the damage factor (β), are introduced in the internal filtration model. They can be determined from either experimental data or empirical correlations. When core flow...
