Слайд 4

Classification of EOR methods

Слайд 5

When are chemical EOR methods used?

Слайд 6

What is polymer
A compound consisting of long-chain molecules, each molecule made up of

1000-10000 repeating units connected together.
Most polymers are based on carbon and are therefore considered organic compounds.

Слайд 7

Mobility Ratio

λ - mobility,
k – permeability,
μ – viscosity.

Слайд 9

Polymer Flooding
Polymers:
Added to water to increase its viscosity
Reduce water permeability due

to mechanical entrapment
Decrease water mobility.

Слайд 10

Polymer Flooding for Enhanced Oil Recovery
help to extract up to 30% of the

original oil in place
help to increase the viscosity of the displacing liquid (water) to drive the displaced liquid (oil) to the production well
