Introduction on importance of EOR.SIBERIAN FEDERAL UNIVERSITY
3. The Russian government and its major oil companies have realized that there is a need to invest in new fields and new regions,
which has led to a focus on East Siberia, the offshore, tight oil, and theArctic.

4. EOR is used when the primary (natural flow) and secondary (water and gas injection) methods are no longer effective and
normally leave around 60-80% of oil unrecovered.SIBERIAN FEDERAL UNIVERSITY
5. Thermal recovery rate is notable.

11. GRAPHS SHOWED THE EFFECT OF PARTICLES SIZE(MICRO , NANO)IN DIFFERENT TEMPERATURE (25°C , 50°C). the tests showed using the
optimum percentage of magnetic particle can reduce the viscosity of heavy oil .Viscousity

• Crude oil is a complex mixture of organic molecules, characterized byparaffins, naphthenes,...
SIBERIAN FEDERAL UNIVERSITY
13.
• the viscosity of nanofluid depends on many parameters such as basefluids, particle size, particle shape, temperature, particle size distribution
and particle aggregation.
The most appropriate catalysts are those containing strong, active sites
that can actively break the C-C, C-S, C-O and related bonds in resins and
asphaltenes, with a net increase in the concentration of saturates and
lighter aromatic hydrocarbons.
SIBERIAN FEDERAL UNIVERSITY
14.
ConclusionSIBERIAN FEDERAL UNIVERSITY
15.
• Viscosity of heavy oil can be decreased by metal particles even atroom temperature, and without applying steam stimulation.
• Catalyzing the hydrogenation reactions of aquathermolysis process
during steam stimulation is the strongest viscosity reduction
mechanism of the metal particles.
SIBERIAN FEDERAL UNIVERSITY
16.
The coordination reactions of transition metal particles with the heavymolecules of oil may dominate(control , influence) the exothermic
reactions effect in longer times. As a result, metal particles may strongly
increase the viscosity.
In order to prevent this effect ,the concentration of particles should be
selected in a way that all the particles be consumed during the high
temperature hydrogenation and hydrosulphurization reactions.
Exothermic Reactions Reactants --> Products + Energy

17.
• To decrease the cost of hightemperature steam ,
Catalytic flooding can Combined with
Thermal methods such as (SAGD).
This combined technology can apply on
wells and
• reduced steam use,
• shortened steam circulation time
• increased initial oil production.
SIBERIAN FEDERAL UNIVERSITY
18.
• Interdisciplinaryresearches should
increased.
