The article shows the results of laboratory tests, field tests and commercial use of new physical and chemical methods for enhanced oil recovery at the late stage of development, including high-viscosity oil. Technology is based on the following concept. Reservoir energy or injected heat transfer agent generates in the reservoir chemical intelligent systems - gels, sols and oil-displacing surfactant compounds that prolong set of properties favorable for oil displacement and control of filtration flow. Technological efficiency of such compositions is proven in the deposits with oil difficult to recover in Russia, China, Vietnam, Oman and Germany. Oil displacement efficiency and sweep efficiency are increased with simultaneous intensification of development. Application of new integrated technologies for enhanced oil recovery at industrial scale will contribute to the development of oil industry, expansion of fuel and energy base in Russia.
