Formation damage, a common problem associated with field operations, is often a major factor in reducing the productivity and injectivity of a well in a petroleum reservoir. The main formation damage mechanisms were considered in the article. Laboratory and field formation damage experiments were analyzed that describes a number of factors affecting on kinetics of permeability damage. As a result a typical relation of permeability reduction was obtained. A profile of permeability distribution related to radius and time of filtration is considered.
