It is known that for well killing saline specified predominantly.However, in some cases, with little repression there is a penetration of liquid into the reservoir which in turn causes a change in permeability in consequence of the interaction of the solution with formation water. In this regard, the article presents the results of research of the changes in the permeability of core samples at Verkhne-Shampinskoye field.
