Effective EOR methods in high-viscosity oil fields: cyclical GEL-polymer flooding and ASP flooding

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 conditions productive reservoirs rich in high-viscosity oils (viscosity reservoir above 300 mPa s) of Buzachi North field, extending boundaries application these methods. used methods hydrodynamic modeling, mathematical analysis; necessary parameters fractures and super for calculating working volumes injected compositions were estimated tracer studies.
