Efficiency analysis of hydrodynamic enhanced oil recovery methods on the example of Las-Eganskoye field

The majority of oil fields in Western Siberia are at the late stage of their development. Therefore, the minimization of economic and technological costs aimed at enhanced oil recovery is becoming a primary task. Hydrodynamic methods of enhanced oil recovery (HM EOR) fully satisfy these requirements, which makes them the most promising in further development of oil fields in Western Siberia. The methodology includes measurement and description, which use allows analyzing and assessing the study of HM EOR application. The purpose of this study is to demonstrate the efficiency of HM EOR on the example of Las-Eganskoye field. The study of hydrodynamic methods of enhanced oil recovery included the analysis of results, which allowed developing recommendations for the implementation of HM EOR in the oil fields of Western Siberia. It is shown that the technological opportunity of HM EOR requires clarification based on the current state of field development taking into account the peculiarities of reservoir pressure maintenance system, technical condition of pipelines and the stock of active injection wells proposed for cyclic injection.
