of thermal conductivity of the reservoir water under the reservoir conditions c p u0302 is coefficient of the specific heat of the reservoir water under the reservoir conditions and u03c1 u0302 is the density of the reservoir water under the reservoir conditions the duration of the pause should not be less than the duration of the pulse at maximum amplitude of the pulse the electrical treatment is discontinued once the decrease of amplitude of the pulse is observed in the example below 1900 a after the maximum 2000 a data obtained from experimental tests of the present method have confirmed the success rate and effectiveness of the method specifically with respect to an increase in oil production rate a decrease in the flooding of the produced fluid and the amount of the additionally produced oil as will be clear from the following description in carrying out the method of the invention it is important to effect enhancement of oil recovery from the treated well or wells this is achieved by the effective use of electrical treatment or stimulation of the oil reservoirs this effect is achieved in the present method for improving reservoir recovery by using a more rational basis as compared with the prior art for screening of wells for electrical treatment of the reservoir while the electrical treatment itself using producing wells is applied based on more adequate and optimized electrical stimulation pulse durations at various stages of the reservoir treatment more specifically electrical stimulation of the oil reservoir using producing wells is conducted in parallel on three sites of the oil or oil and.
