ABSTRACT
To demonstrate the knowledge gained in the oil and gas process and also the
management itself, specifically in the Bolashak Oil and Gas processing plant.
Introduction
Refers to the location, characteristics, and history
of the plant.
Produced up to 450,000 barrels of
oil and 8.8 million cubic metres of
gas per day
Located 40 km north-west
of Atyrau in Kazakhstan.
Launched in June 2013.
Generated more than 2,500 jobs
Bolashak oil and gas
processing plant
Built as part of Kashagan
project
First oil production at the plant
is expected by the end of 2013

CRUDE STABILIZATION
PROCESS
What is Crude Stabilization Process?
●
Removal of light components from a hydrocarbon liquid to lower its vapour pressure to a
desirable level
●
To meet the requirements of a pipeline sales contract
●
Reduces the quantity of intermediate hydrocarbon components (propane and butane)
that flash to vapour, resulting in an increase in liquid volume.
●
Separators: A mechanical equipment used for the separation operation
○ Two-phase separator
○ Three-phase separator

Crude Stabilization Process
Bolashak OnG Processing Plant
at
●
Crude oil from the Kashagan oil field is
first introduced into separation operation
●
3 separator stages offshore on D-island
●
The High pressure hydrocarbon will flow
through the HP Separator, Continuing to
MP Separator, and lastly, LP Separator
○
to knock off the liquids from the
flow stream
●
The stabilizer:
○ located onshore,
○ fourth separation stage.
○ Gas from the stabilizer is mixed with
offshore gas and sent to Sulphur
Recovery Unit (SRU) for H2S removal
○ Stabilized oil will be processed for
further export.

Gas and Crude
Treatment
WHAT IS GAS AND CRUDE TREATMENT ?
●
Gas treatment: the process of removing contaminants and impurities
from natural gas or biogas, such as water, carbon dioxide, hydrogen
sulphide, and other trace components
●
Crude treatment : crude oil treatment describes the procedures used
to separate the different parts of crude oil and eliminate impurities.
WHY DO WE NEED A GAS AND CRUDE TREATMENT ?
●
To remove impurities and contaminants from the extracted gas and
crude oil.
●
To achieve pipeline specifications, adhere to safety regulations, and
avoid equipment corrosion and failure, purification is required.
●
For the safety of workers in the oil and gas sector and protect the
environment .

CONTAMINANT REMOVAL
AND RECOVERY
Refers to the refining process of the feedstock after going through gas and crude treatment
What is Contaminants Removal and
Recovery?
Based on our case study…
Bolashak Processing Plant
Specializes in gas and crude
treatment.
Atyrau Refinery Plant
Refines the feedstock provided by
the Bolashak Processing Plant
Contaminants Removal
The main contaminant removed is sulfur.
Contaminant Recovery
THE ECONOMICS OF PETROLEUM OPERATIONS
MARKET DEMAND AND PRICE
COVID-19 pandemic caused a
slowdown in the world economy
and decreased demand for oil
and gas.
PROCESSING COST
the cost of refining crude oil into
different petroleum products such
as gasoline, diesel, and jet fuel.
EXTRACTION COST
extraction costs can be high due to
the remote location and complex
geological structures of the field.
EMPLOYMENT FACTOR
provides employment opportunities
for workers in various industries,
such as engineering, construction,
transportation, and maintenance.

Conclusion
The Bolashak Processing Plant is a
significant oil and gas processing facility
located in the Atyrau region of
Kazakhstan.
Conclusion
In this process, the raw natural
gas and crude oil are treated to
remove impurities, such as
water, sulfur compounds, and
other contaminants.
The process of removing light
hydrocarbons, such as butane
and propane, from the crude oil
to make it safer for
transportation
The plant's joint venture structure with several
international oil companies helps to mitigate
some of the risks and uncertainties involved in
petroleum operations, while also providing
opportunities for collaboration and shared
resources.
Hydrotreating is primarily used
to remove sulfur compounds
from the feedstock.
