In condition of oil saturated reservoir development the achieving of high values of the conformance factor during the reservoir development by water flooding methods requires solving a number of additional tasks related to the studying of the causes and the nature of premature water encroachment of productive formation. Based on the obtained information the selection of the effective methods for controlling of the movement of water is performed as well as and choice of the optimal application conditions in the field development system in order to increase the oil recovery factor is done. One of such methods is the creation of the watertight barriers in the critical zone of the wellbore. For this purpose wall-sealing composition like REPLAST are introduced.
