Development of reservoirs with high oil viscosity is usually challenging because of requirement to apply comlex technologies for economical efficient oil recovery. East Messoyakhskoye oil field is a complex project both from geological caracteristics (viscous oil with viscosity 111 cP, highly heterogeneous reservoir with permeability 50-2500 mD, presence of gas cap and aquifer) and due to its remote location (arctic climatic conditions, no transport and industrial facilities). Main reserves are located in reservoir PK, senomanian formation. At the field development plan stage calculations showed requirement of flooding for reservoir pressure maintenance, but waterflooding expected to be risky due to fingering and it was obvious that for efficient reservoir development enhanced oil recovery methods should be considered. This paper presents choosen enhanced oil recovery strategy, the way passed in polymer flooding implementation and current results.
