An assessment of the potential of polymer flooding at an oil field in Western Siberia

   The operational object under study has a high current water-cut and is at the final stage of development.   The aim of the study is to assess the potential for polymer flooding at the object X of the deposit C through hydrodynamic calculations.   Hydrodynamic modeling is performed on a synthetic model cut from a sector model of the reservoir. This model meets the criteria for selecting sites, corresponds to the parameters of a full-scale model. However, it is more detailed, which is why it was chosen to substantiate the effectiveness of polymer flooding. The model specifies the actual well location, which is in the most characteristic zone of the reservoir with the actual development system. The results of the hydrodynamic calculations demonstrated the technological efficiency of polymer flooding at the object X. The increase in the oil recovery factor was 1.85 %. Further plans include further laboratory studies of polymer solution properties, an economic assessment to select the optimal concentration and volume of polymer solution injection, and a decision on conducting pilot work.
