The presented work discusses increasing oil recovery factor using physicochemical EOR methods.
This article presents the field pilot tests results related to cyclical gel polymer flooding technology as applied under the conditions productive reservoirs rich in high-viscosity oils (viscosity in reservoir conditions above 300 mPa s) of the Buzachi North oil field, extending the boundaries of application of these methods. The work used the methods of hydrodynamic modeling, mathematical analysis; the necessary parameters of fractures and super reservoirs for calculating the working volumes of the injected compositions were estimated using tracer studies.
