The crude oil is
evaporated because it
has different boiling
points, so its vapours
allowed to condense at
different temperatures
in the fractionating
column. Each fraction
contains hydrocarbon
molecules with a similar
number of carbon atoms
anddifferent properties
Conversion processes /
Cracking
Takes the
long carbon
chains of
heavy gas oil
and breaks
them into
shorter-chain
hydrocarbons.
Hydrocracking
Fluid catalyst
Treatment
is a process
designed to
increase
the volume
of gasoline
that can be
produced
from a
barrel of
crude oil.
Gasoline’s
octane rating
measures its
resistance to
“engine knock.”
Gasoline vapor
heats up as the
cylinder
compresses it; if
it heats up too
quickly.
Formulation and mixing
Additional
hydrogen
formed by the
catalytic
reactors is
recovered and
put to use in
subsequent
reforming and
in other
processes
throughout
the refinery.
Extraction
Location
Engineers recollect above-ground
information using airplanes and
satellites to map the surface, to
identify promising geological
formations.
They look for certain kind of rocks
that may contain under some
bags of Oil and natural gas.
Drilling
Types
Drill Ship
Jackup Drill Rigs
Slim Hole Drilling Rig
Semi-Submersible Rigs
Coiled Tubing Drill Rig
Land Based Drilling Rigs
It's how a ring goes
under the water or soil
with a big rock smasher
head, then a tube
extracts all the oil.
Extraction
&
transportation
There are three phases
of extraction:
Primary recovery
The underground pressure
drive fluids to the surface.
When the pressure falls,
artificial lift technologies, such
as pumps, are used help bring
more fluids to the surface. In
this action only 10% of the Oil is
extracted .
Secondary recovery
Water that is
produced and
separated from
the oil in the
initial phase of
drilling is injected
back into the
oil-bearing
formation to
bring more oil to
the surface. In
this action only
the 30% of the
Oil is extracted.
Enhanced recovery
These are the three
techniques used to extrac
60% of the Crude Oil
Thermal
They inject
steam in the Oil
bag. The heat
from the steam
makes the oil
flow more easily,
and the
increased
pressure forces it
to the surface.
Gas injection
They inject
propane,
methane or
other gasses
in the oil to
lower its
viscosity
and increase
flow.
Chemical
water-soluble
polymers with
water and
injecting the
mixture into
the field. The
water pushes
the oil out of
the formation.
