What is enhanced oil recovery
method?
Enhanced oil recovery (abbreviated EOR), also called tertiary recovery, is the
extraction of crude oil from an oil field that cannot be extracted otherwise.

Let's talk about our reservoir
API gravity of our reservoir is 35 API
Light crude oil: API gravity higher than 31.1 °API (less than 870
kg/m³)
Medium crude oil: API gravity from 31.1 °API to 22.3 °API (870 to 920
kg/m³)
Heavy crude oil: API gravity from 22.3 °API to 10 °API (920 to 1000
kg/m³)
Extra-heavy crude oil: API gravity below 10 °API (higher than 1000
kg/m³)
Light crude oil
As API is lower,
than it means that
heavier is our oil.
Viscosity of our reservoir is 3 cp
Viscosity increases with decreases in
crude oil API gravity (assuming a
constant Watson characterization
factor) and decreases with increasing
temperature.
It depends entirely
on the diagenesis
and oil formation
process
Permeability of our reservoir is 56 md
Permeability is a measure of the ability of a fluid
to pass through its porous medium. Permeability
is one of important to determine the effective
reservoir.
Porosity of our reservoir is 19.4%
It is defined as a measure of
the capacity of reservoir rocks
to contain or store fluids
