Abstract:
This article examines the nature of current oil recovery and knowledge of residual
oil types, which is especially important when developing and introducing new ways to increase oil
recovery. In this regard, the geological characteristics, features of natural reservoirs, heterogeneity of reservoirs and properties of oil from some fields have been studied. Physical and chemical indicators of oil were investigated, as well as samples of produced water from the Kokzhide deposit were analyzed for further research on the possibility of using polymers for enhanced oil recovery.
