9. Process Presentation

10. Oil Exploration
Long ago, except in areas where oil
flowed naturaly, the discovery of
deposits was often a matter of intuition
and luck. Today, prospectors, based on
their geological knowledge of the
structure of oil traps, focus on areas
where the black gold is most likely to
have formed. They know, for example, it
may be present in one of the 600
identified sedimentary basins on the
planet.
To date, about 160 of these basins
provided oil; 240 have nothing given.

11. Drilling
Drilling is the only way to ensure that an oil or gas field really exists, and what
kind of oil it contains.

14. Onshore Installation
In the beginnings of oil exploration, oil was
not far from the surface.
Countless wells were drilled to reach it.
Sometimes it flowed naturally under the effect
of its own pressure. But after a while, the
pressure in the water table dropped and the
precious liquid must be pumped. We, then,
put in place pumps with typical form provided
with a rocker whose mechanical principle has
remained the same until today: When the
head in an arc is down, the plunger of the
pump lowered into the well. When the head
rises, the plunger sucks the oil to the surface.

15. Offshore installations
Large oil reserves exist beneath
the floor of the oceans. To exploit
it, we install offshore hosting
platforms drills whose head
plunges into the rock of the
seabed. Oil is then sent the rock
through pipelines or it is stored in
floating facilities before being
transferred in oil ships.

17. Crude Oil
Crude oil is a complex mixture of up to
200 or more of various organic
compounds, primarily hydrocarbons.
Different crude oil compositions
containing various combinations and
concentrations of these various
compounds.
API gravity (American Petroleum
Institute) of a particular crude oil is
simply a measure of its specific gravity,
or density.
17

18. Naturel Gas
The natural gas used by consumers is
composed almost entirely of methane.
However, natural gas found in the
wellhead, although still mainly
composed of ethane, is not pure.
The natural gas comes from three types
of wells: oil wells, gas wells, and
condensate wells.
18

19. Oil refining
Oil refining is the transformation of crude oil into finished petroleum products.

20. Oil refining
Gradual Process
In a fractionating column, the
temperature is controlled. It
gradually decreases with height, so
each fractionation tray is cooler
than those below.
From each stage, there are
emerging pipes through which are
evacuated the various petroleum
fractions as they condense on the
trays.
The light products such as gas, are
recovered at the top, the heavier
fractions at the base. Hence, piping
outweigh each fraction to the next
stage of refining.

Mascaras, cleaners, clothes,
shoes, PVC doors and windows,

22. Process Overview
22

23. Wellheads
The wellhead is located at the top of
oil or gas leading to the tank. A
wellhead can also be used for
injecting water or gas into the
reservoir to maintain pressure and
levels to maximize production.
23

24. Gathering Manifolds
The Gathering manifold is a
fitting system connected to a
main pipe used to divide a flow
into parts, combine multiple pipes
into one, or to redirect a flow to
one of several possible
destinations
24

25. Separation
Some wells have a production of
pure gas that can be taken directly
to the treatment and/or
compression of gases.
Most often, the well results in a
combination of gas, oil and water
and other contaminants which
must be separated and treated.
production separators come in
many shapes and designs, with the
classical variant being the gravity
separator.

27. Separation
Test separators are used to
separate the wellstream from
one or several analysis wells and
measurement of detailed flow.
In this way, the behavior of each
well in the pressure of flow
conditions can be determined.
27

28. Gas Compression
The gas from a pure natural gas
wellhead may have sufficient
pressure to be directly
transported by pipeline.
Gas from the separators
generally lost so much pressure
that must be compressed for
transport.
28

29. Storage
29

30. Storage
Most stations do not allow the local
storage of gas, but the oil is often
stored in tanks before loading on a
"Tanker".
Offshore production facilities without
direct pipeline connection usually
based on storage in the base to allow a
shuttle tanker to unload about once a
week.
30

31. Metering
The metering stations allow operators
to monitor and manage the natural gas
and oil exported from the production
facility.
These metering stations use
specialized instruments to measure
natural gas or oil flowing through the
pipeline, without disturbing its flow.
31

32. Metering
The measured volume represents a
transfer of property from one
producer to a customer (or another
division within the company).
This transfer is called "Custody
Transfer". It is the basis for billing the
product sold and also for taxes on
production and revenue sharing
between partners.
Accuracy requirements are often set
by government authorities.
32

33. Metering
33

34. Export
Pipelines can measure 6 to 48 inches in
diameter.
To ensure the efficient and safe
operation of pipelines, operators
regularly inspect pipelines for
corrosion and defects. This is done
through the use of equipment known
as the 'Pigs''.
The '' Pigs '' can test the thickness of
the pipeline and the roundness check
for signs of corrosion and leaks and
other defects along the interior of the
pipeline.

35. Water Treatment
On such a facility, when the cutting
water is high, there will be a huge
amount of water produced. For
example, a cup of water 40% gives a
water production of about 4,000 cubic
meters per day (4 million liters) which
must be cleaned before being
discharged to the sea.
Environmental regulations in most
countries are very strict.
35

36. Injection Wellheads
The wells are also divided into
producing wells and injection wells. The
first is for the production of oil and gas.
The injection wells is used for injecting
gas or water in the wells.
The purpose of the injection is to keep
the pressure in the reservoir and forcing
the oil so that it moves towards the
production well.

37. Utilities

38. Utilities – Power Generation and distribution
Power can be provided by the sector or
local diesel generators.
Large facilities have large power
requirements, 30 MW and up to several
hundred MW. There is a tendency to
produce centralized power and use
electric motors for heavy equipment
rather than more gas turbines because
this reduces maintenance and increases
uptime.

39. Utilities – Power Generation and distribution

40. Utilities - Flare system
The Flare System collect and
discharge gas to safe locations during
normal operations and abnormal
conditions (rescue, emergency).
Flare systems usually have a pilot
device or ignition device that ignites
the gas leaving the system because
the discharge can be either
continuous or intermittent.
40

41. Utilities – Control & Safety System
A process control system is used to
monitor data and control
equipment in the station.
Smaller facilities may use hydraulic
or pneumatic control systems, but
larger plants with up to 20,000
signals to and from the Process
requires a distributed control
system.
41

42. Utilities – SCADA
The SCADA (Supervisory Control and Data Acquisition) is associated with
telemetry and communication for data collection and control on large
production facilities, pipelines, or company data from multiple facilities.
42

43. Utilities - Instrument Air
A large volume of compressed air is
required for the control valves and
pneumatic actuators, tools and
purging cabinets. It is produced by
screw compressors driven by an
electric motor and further treated
to be free of particles, oil and water

44. Utilities - HVAC
The HVAC (Heat, Ventilation and Air
Conditioning System) provides air
conditioning in the rooms of
equipment, accommodation, etc.
Cooling and heating are performed by
means of chilled water or water/
steam heated by the heat exchangers.
Heat can also be removed from the
exhaust gas turbine.
