5. When are chemical EOR methods used?

Chemical EOR
methods are
used for:
Objects of
application:
Additional extraction
of oil from heavily
depleted
Deposits with a low
viscosity of oil (not
more than 10 mPa.s)
Flooded oil reservoirs
with dispersed,
irregular oil saturation
Low salinity of water
Productive layers are
represented by
carbonate reservoirs
with low permeability

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.
