Abstract

The paper presents the results of comparative evaluation of oil displacement ability of a new composition based on deep eutectic solvents (DES), surfactants and IKhN-PRO composition previously developed in IPC SB RAS. Laboratory modelling of oil displacement process of heavy oil of Usinsk field on models of heterogeneous reservoir with carbonate type of reservoir showed that both compositions have high oil displacement ability in a wide temperature range, opening the possibility of their use at any stage of field development.
