oa EOR Application in Large Oil/Gas Fields of West Siberia: Generalisation of the Experience, New Technologies

More than 30% of oil and gas-condens ate reserves in Russia are contained in the oil fields having gas caps. Annual recovery race of such reserves is less than 6%. Race of oil production and oil recovery factor are also very low. The discovery of giant oil fields in the West Siberia, such as the Samotlor oil field, the Lyantor oil field and the Fyodorovskoe oil field as well as many other fields, has demanded application of new technologies for the development of wast under-gas zones.
