However, when including the effect of filtration, the viscosity of the does not increase due to exclusion...

... in low permeability zone by blocking up easy channel when cross-linked with aluminum ion. However, we got the results that the CNF suspension shows poor injectivity because filtration occurs in the sandstone core during injection. enhanced recovery chemical flooding methods CNF suspension...

... The results of laboratory studies on deep bed filtration of oily particles are in a fairly good agreement with predictions by traditional suspension flow models 10 – 15 . The above-mentioned suspension transport studies do not account for the presence of residual oil in rocks. Abstract...

... effects was derived. The effect of the total oil-water mobility variation on injectivity is particularly significant for cases of heavy oil and relatively low formation damage. The injectivity decline formula derived allows for determination of filtration and formation damage coefficients and filter cake...
