The migration of residual oil is partial flow of reserves that was displaced into zones with no production wells or from unswept zones after well shutting. This process is facilitated by favorable geological conditions, such as high continuity, permeability and connectivity of the formation, and the presence of anticlinal dome. Based on the results of drilled transit wells, the oil migration effect was confirmed, recommendations
for further development of shallow marine sandstone of one of the fields in Western Siberia were given.
Materials and methods
This paper presents an algorithm for oil field secondary development at a late stage of development, is proposed, which includes
the integration of research: selection and analysis of a new core, revision of the reservoir properties of rocks, conducting gyroscopic studies on old wells, analyzing the saturation of transit wells, rebuilding a hydrodynamic model with new data.
oil migration, the last stage of oil field development, the development
of residual oil reserves
