Abstract: The method describes a way of improved oil recovery by the action of the electric field of the DC current and the electromagnetic field on the oil deposit (6) that is on the oil, the mentioned method comprises the following steps: a) Selection of the submerged rock clusters formations that contain the oil; b) Selection of one or more boreholes wells where the method will be applied; c) Extracting oil from at least one well borehole; Considering that the afore mentioned steps of the method further comprise of the following steps: A. Connected steel (17) and/or the upstream production tubing (16) of the boreholes wells with the DC electricity source 1 where the steel casings (17) and/or the upstream production tubing (16) assume the roles of the electrodes (7, 8); B. Connecting an electrical current source (1) with an electromagnetic field source (2); C.
