T E C H N O L O G I E S FOR ENHANCED OIL RECOVERY |
|
GALKA systems, inorganic gels intended to reduce water cut and thereby to enhance oil recovery at waterflooding and at thermal stimulation of oil reservoir.
METKA systems, thermoreversible polymer gels for enhanced oil recovery intended to reduce water cut and to prevent gas breakthrough.
EOR of low-permeable formations by IKhN systems based on surfactants and alkaline buffer solutions.
EOR of low-permeable reservoirs with high formation temperatures by surfactant-based IKhN-KA systems.
Increase in the efficiency of thermal-steam treatment of high-viscosity oil reservoirs by surfactant-based NINKA systems, generating CO2 and an alkaline buffer system in situ.
Combined EOR technologies involving both gel-forming and oil-displacing systems, including high-viscosity oil fields.
Cryotropic gels aimed to create cutoff curtains and to harden soils in the permafrost regions.
Additional oil recovery ranges from 400 to 10,000 tons per one well treatment (on average 1-3 thousand tons per one well treatment).
50-300 tons of the systems are required to treat one injection or production well.
All the reagents applied are available products of large-tonnage industrial production.
Payback period is 5-12 months.
The technologies developed are covered by 20 RF patents and by 1 patent of China.
4 license agreements have been signed.
All the technologies have been tested in oil fields of Russia (Nizhnevartovsk, Langepas, Strezhevoy, Kogalym, Nyagan, Yugansk and Ukhta) and in Vietnam.
The technologies are commercially employed in oil fields of West Siberia and in Komi Republic by Lukoil and Yukos Oil Companies. About 200-300 wells are treated every year.
During 5 recent years additional oil recovery amounted to more than 1.5 million tons due to application of EOR technologies developed at the Institute of Petroleum Chemistry RAS.
