The article is devoted to the analysis of the field preparation of hard-to-recover oils on the example of a field in Kazakhstan. On the basis of laboratory and field studies, the physicochemical properties of oil emulsions were studied, the characters of the emulsion were identified by the type of natural stabilizers, the group composition, their aggregate stability, as well as rheological features were determined. In the article the main reasons that complicate the processes of field preparation of hard-to-recover, rheologically complex oils were analyzed and identified. Some ways of improving the efficiency of field treatment of high-viscosity oils in the presence of intensive technogenic impact on the formation in order to increase the oil recovery factor are also indicated.
