This document discusses the major elements and types of offshore oil and gas production systems. The key components include wells, platforms, pipelines, and tankers. There are several types of offshore platforms suited for different water depths, such as fixed platforms anchored directly to the seabed suitable for depths up to 1,700 feet, semi-submersible platforms that can float and be moved to depths from 200 to 10,000 feet, and drillships equipped with dynamic positioning that can operate in water depths up to 12,000 feet. Floating production systems like FPSOs are also discussed. The document provides details on platform components, maintenance, crews, and essential personnel needed to operate offshore oil and gas production facilities.
Offshore platforms are structures installed in bodies of water to facilitate petroleum drilling and production. There are several types of offshore platforms including fixed platforms, compliant platforms, and floating platforms. Fixed platforms are directly fixed to the seabed and include jacket platforms and gravity-based structures. Compliant platforms, like tension leg platforms, use tethers to connect to the seabed and allow for some movement. Floating platforms are not directly attached and include semi-submersibles and FPSOs (floating production, storage, and offloading vessels).
A subsea completion involves installing well equipment on the seafloor such that the producing well does not have a vertical conduit back to a fixed offshore structure. It consists of a production tree, upper completion connecting the tree to the lower completion, and a lower completion installed across the producing intervals. Subsea completions provide environmental and economic benefits over other offshore development alternatives in deep waters. However, their success relies on maintaining production over time without interruptions, which requires addressing regulatory, safety, economic, technological, and environmental factors.

Oil 101: Introduction to Oil and Gas - Upstream
What is Upstream? This Midstream content is derived from our Oil 101 Upstream ebook and can be found in our oil and gas learning community.
This Upstream module includes the following sections (use the links below for quick access):
-Introduction to Upstream
-Upstream Business Characteristics
-Oilfield Services
-Reserves – Formation and Importance
-Production – The First Step in Adding Value
-The Unconventional Future of Upstream
Upstream
What is Upstream? Most oil and gas companies’ business structures are segmented and organized according to business segment, assets, or function.
The upstream segment of the business is also known as the exploration and production (E&P) sector because it encompasses activities related to searching for, recovering and producing crude oil and natural gas.
The upstream segment is all about wells: where to locate them; how deep and how far to drill them; and how to design, construct, operate and manage them to deliver the greatest possible return on investment with the lightest, safest and smallest operational footprint.
Exploration
The exploration sector involves obtaining a lease and permission to drill from the owners of onshore or offshore acreage thought to contain oil or gas, and conducting necessary geological and geophysical (G&G) surveys required to explore for (and hopefully find) economic accumulations of oil or gas.
Drilling
There is always uncertainty in the geological and geophysical survey results. The only way to be sure that a prospect is favorable is to drill an exploratory well. Drilling is physically creating the “borehole” in the ground that will eventually become an oil or gas well. This work is done by rig contractors and service companies in the Oilfield Services business sector.
Production
The production sector of the upstream segment maximizes recovery of petroleum from subsurface reservoirs.
perforated joint, flow coupling and blast jointElsayed Amer
This document discusses perforated joints, flow couplings, and blast joints used in downhole equipment. A perforated joint is installed above a no-go and provides flow bypass when gauges are installed. It must have a total cross-sectional area of holes equivalent to the tubing internal diameter. Flow couplings are installed where turbulence is expected, such as above and below crossovers or nipples, and have thicker walls to prevent early erosion failures. Blast joints are placed near perforations and have heavy, blast-resistant coatings to protect from extreme erosional forces opposite open perforations.
The document discusses well completion and testing methods. It begins with welcoming 7th semester mining students and introducing the instructor. It then provides definitions and overview sections on well completion, well testing, and drill stem testing. The document describes different well completion methods like open hole, cased hole, liner, and tubing completions. It also discusses wellhead equipment, well testing operations, and considerations for high pressure and high temperature testing. Overall, the document provides information on various aspects of well completion and testing.
Crude oil production systems involve exploration, drilling, and surface production operations to extract crude oil and separate it from other fluids and gases. Surface production operations include separating the well effluent into gas, oil, and water streams using separators. The separated streams undergo further treatment, which may include dehydration to remove water, emulsion breaking, stabilization to control vapor pressure, and removal of impurities. Produced water is typically reinjected, while associated gas may be reinjected, used for power generation, or flared if not needed onsite. Wastes are also handled through treatment and disposal or reuse to protect the environment.
Scsssv surface control subsurface safety valveElsayed Amer
The document discusses subsurface safety valves (SSSVs), which are installed downhole to allow emergency shutdown and prevent uncontrolled hydrocarbon release from a well. SSSVs were not in place during the Piper Alpha platform disaster, exacerbating the accident. SSSVs come in two types: wireline-retrievable, which can be easily installed/removed via wireline but restrict flow; and tubing-retrievable, which are integral to the tubing and avoid flow restrictions but require pulling tubing for repair. Recommended minimum setting depths are 50m below the deepest pile for offshore and 100m below ground level for onshore. [/SUMMARY]
Bullheading is a common non-circulating method for killing live wells prior to workovers. It involves pumping kill fluid into the tubing to displace produced fluids back into the formation. A bullheading schedule is generated using formation pressure, desired overbalance, fracture pressure, tubing specifications, and pump data to safely control pumping pressures within the initial and final maximum pressures. The schedule provides checkpoints to monitor pumping pressure and volume throughout the operation. Special attention should be paid to any increases in casing pressure which could indicate downhole issues.
The first presentation of a series of presentations on Operations Geology. Very basic, just to introduce beginners to operations geology. I hope the end users will find this and the following presentations very helpful.
This document provides an overview of subsea field development. It discusses key considerations like deep water vs shallow water development, wet tree vs dry tree systems, standalone vs tie-back development, and artificial lift methods. It also covers topics like subsea processing, template and clustered well systems, and daisy chain configurations. The document compares standalone and tie-back developments and outlines the decision process for selecting between the two options.
Sucker rod pumps are a type of artificial lift used in oil wells that involves components both above and below ground. The surface pumping unit is connected via sucker rods to the subsurface pump located downhole. The pumping cycle involves the plunger moving up and down inside the barrel, using the traveling or standing valves to draw fluid into the barrel on the upstroke and push it up on the downstroke. Sucker rod pumps are suitable for shallow wells producing 10-1000 bbl/day but become less effective at greater depths or in wells with high gas levels.
This document discusses well completion design, selection, and operations. It provides an overview of the sequence of well drilling and completion. It describes common casing programs and marks the starting point of completion. It also details the metals commonly used in completion equipment and describes various downhole completion tools like tubing hangers, packers, and wireline entry guides.
Horizontal vertical christmas tree pptAmar Gaikwad
Brief Information about Christmas tree that is Sub-sea horizontal vs vertical x-mas tree. in this presentation include information that is types of x-mas tree,tree selection & last is which tree is most preferable for surface and subsurface applications.
This document provides information on gas lift valve mechanics, including the three basic types of gas lift valves, how they operate, and the forces involved in opening and closing them. It discusses unloading valves, orifice valves, and how gas lift valves close in sequence from the bottom of the well upward. Diagrams show the components of different gas lift valve designs and the formulas used to calculate valve opening and closing pressures.
This document provides an introduction to drilling rigs and drilling technology. It discusses the key systems that make up a drilling rig, including the rig system, power system, mud handling system, hoisting system, rotary system, well control system, and instrumentation system. It also discusses drilling technologies such as mud, casing, rigs, hydraulics, bits, drilling, cementing, and special technologies like directional drilling. Finally, it outlines the main operations involved in drilling a well, from rig building to well head fitting and testing.
This document discusses different types of drilling rigs used on land and offshore. It describes land rigs as heavy, light, portable, and conventional. Offshore rigs include floating rigs like drill ships and semi-submersibles, bottom-supported rigs like jack-ups and fixed platforms, and barge and submersible rigs. It then compares stationary and mobile land rigs, noting stationary rigs have advantages like faster tripping speeds but require more investment, while mobile rigs have less investment costs but slower tripping speeds and drilling depth restrictions.
A multilateral well connects two or more standard well types, such as vertical, deviated, or horizontal wells. It allows multiple production laterals to be drilled from a single surface location. The value to customers is that multilateral wells can significantly increase production from a field by drilling more reservoir contact from fewer well pads and surface locations. There are different technical levels for multilateral wells based on how the junctions between the main and lateral bores are constructed and supported. Higher technical levels provide more completion flexibility but also more complex construction.

Post Recession Offshore - Oil & Gas IndustryAftab Hasan
This document provides an overview and outlook of the global offshore oil and gas industry following the economic recession. It discusses factors influencing the offshore market such as increasing global energy consumption and the cyclic nature of oil prices. The financial implications for the offshore industry are also examined, noting growing investment in deepwater and horizontal drilling while fleet utilization does not yet require additional rigs. The outlook for offshore energy vessels is cautiously optimistic, with demand for rigs and support vessels increasing but the market remaining cautious about new builds. The conclusion is that as onshore reserves deplete, offshore exploration and production will extend into new basins, creating opportunities for industry growth.
Drilling fluid technology, Oil & Gas IndustryMohamed Rashid
The formulation of drilling fluid is one of the most important aspects in drilling engineering. This is because the drilling fluid is capable of lubricating and cooling the drill bit and drill string as well as carrying cuttings out of the borehole. All of these functions require appropriate viscosity of drilling fluid to facilitate pumping, circulate the cuttings, and transfer them to the surface.
Oil 101 - A Free Introduction to Oil and Gas
Introduction to Oil and Gas Production
Today we’re going to talk about the production function of Upstream. If you missed the previous podcasts on Upstream Fundamentals, Exploration and Drilling, be sure to go check those out. We’ll put the relevant links in the program notes.
The Production and Offshore Construction Module provides a high level overview of production operations. It introduces the offshore contractors and production service providers that assist E&P companies in efficiently producing oil and gas.
We’ll also cover well completions and key measures and drivers that influence production business operations.
We’ll also give some historical perspective on this part of upstream oil and gas operations.
Production
Once oil or gas is found with a wildcat or discovery well, the next step in adding value to reserves is to get the reservoir fluids brought to the surface, or “produce” them. After all, upstream is also called E&P!

Introduction into Oil and Gas Industry. OIL: Part 1Fidan Aliyeva
The document provides an introduction to the oil and gas industry, covering the following key points in 7 sentences or less:
Oil formed from the remains of ancient organisms over millions of years. It varies in composition and properties depending on its origin. Major oil producers and traders include OPEC countries, international oil majors, and national oil companies. OPEC coordinates policies to stabilize oil markets and ensure supply. While oil reserves could last over 40 years at current production rates, consumption is rising. Large price fluctuations can significantly impact oil-producing and consuming economies. The industry is working to increase capacity and ensure secure long-term oil supplies.
Introduction to Oil and Gas Industry from Upstream (Exploration & Production), Midstream (Transportation & Storage), to Downstream (Refining, Petrochemical, & Marketing)
C1. Introduction to Offshore Production TechDavid Seow
The document discusses offshore oil and gas production and focuses on floating production storage and offloading (FPSO) platforms. It describes FPSOs as having four key functions - floating, production, storage, and offloading. FPSOs are preferred for remote locations, smaller marginal fields, deep waters where fixed platforms are not viable, and areas where mobility is needed to avoid harsh weather. Their modular, self-contained design also makes them easier to decommission and reuse compared to fixed platforms.

It explains that the key considerations for FPSO layout include cargo capacity, equipment location, hull structure, and integration of marine and topside systems. Internal turrets are suitable for deep water and large numbers of risers, while external turrets eliminate the need for a CALM buoy but risk slamming in large waves. Choosing between internal and external turrets depends on factors like water depth and wave height. An internal turret's position varies along the vessel length depending on its active stationkeeping abilities.
There are several types of offshore structures used to explore for oil and gas, categorized based on their geometry and behavior. Fixed platforms include steel template structures and concrete gravity structures, which are fixed directly to the seabed. Compliant structures like compliant towers and tension leg platforms are able to withstand lateral forces through deflection. Floating structures include floating production systems and floating production, storage, and offloading systems which are anchored or dynamically positioned. The type of structure used depends on the water depth, with fixed structures generally under 500m, compliant structures from 300-600m, and floating structures from 600-2500m.
The document provides information on different types of oil and gas drilling rigs used on land and offshore. It describes key components and uses of land rigs, as well as differences between light, medium, and heavy duty land rigs. For offshore rigs, it discusses jackup rigs, gravity platforms, semisubmersibles, tension leg platforms, spars, drillships and their applications in different water depths. Specific rigs like the Berkut and Seastars platforms are also summarized.
This document provides an overview of offshore platform design, including the types of platforms used (fixed and floating), their key components, installation processes, and considerations for hydrostatics and stability. The main types of fixed platforms are jacketed, gravity-based, and compliant tower structures, while floating platforms include tension leg platforms, semi-submersibles, spars, and FPSOs. Design depends on water depth and intended facilities. Corrosion protection and foundation design are also important aspects.
Piping is used to transport liquids, gases, and fluidized solids from one location to another. It forms the backbone of many industries like oil and gas, refineries, and power plants. Seismic surveys use sound waves to image underground rock structures and identify potential reservoirs of oil and gas located beneath the seafloor or land.
Offshore platforms are large structures located at sea that house crews and machinery used for exploring and producing natural resources like fossil fuels from under the ocean bed. There are various types of offshore platforms including fixed platforms, compliant towers, jack-up platforms, semi-submersible platforms, drillships, tension-leg platforms, SPAR platforms, and unmanned installations. Over 6,500 offshore oil and gas platforms are located around the world, with the largest numbers in the Gulf of Mexico, Asia, and Europe. Platforms can be either fixed to the seabed or floating, and are used to extract resources from shallow to very deep waters.
Offshore drilling began in 1896 off the coast of California when an oil rig was constructed on a pier extending into the Pacific Ocean. Early offshore rigs were barges that were sunk into shallow coastal waters and marshes near shore, with drilling equipment placed on the deck. The first steel offshore platform was built in 1947 in the Gulf of Mexico. There are several types of offshore drilling rigs and platforms used today including semi-submersibles, fixed platforms, jack-up rigs, drill ships, and floating production units. Each type is suited for different water depths and designed for stability, mobility, and long-term oil and gas production.
Offshore storage systems are used for early production systems, marginal wells, deep water wells, and temporary storage. There are three main types: floating storage using converted tankers, fixed storage placed on the sea floor, and semi-submerged buoys. Separate production, storage, and loading systems have advantages like easier replacement, while integrated systems use one structure for all three functions. Common offshore storage options include converted tankers, spar buoys, and submerged tanks. Floating storage is often used for marginal fields through FPSOs, converted semi-submersibles, or tension leg platforms.
This document provides an overview of petroleum drilling fundamentals, including different types of rigs used for offshore drilling. It discusses jack-up rigs, semi-submersible rigs, drill ships, condeep platforms, jacket platforms, and tension leg platforms. It also covers well planning, designing the well, drilling operations, completions, new technologies, and structural geology. Key steps in drilling include obtaining licenses, exploration, appraisal, development, maintenance, and abandonment of oil and gas fields. Safety and monitoring drilling progress are also emphasized.
The document provides an overview of the oil and gas industry, describing the upstream, midstream, and downstream sectors. Upstream involves exploration and production of oil and gas. Midstream involves transportation and storage. Downstream involves further processing of oil and gas into end products or raw materials. The document uses Chevron as an example of an integrated oil and gas company that operates across all three sectors of the industry.
Piping is used to transport liquids, gases, and solids between locations. Pipes have a nominal bore diameter and wall thickness specified by a schedule number according to standards. Piping is key infrastructure for industries like power plants, oil and gas, refineries, and more. Offshore platforms explore for and produce oil and gas from the seafloor. They operate in shallow, deep, and ultra-deep water. Offshore processes include exploration using seismic surveys, drilling wells, and production including infrastructure that withstands harsh ocean conditions.
The document outlines the life cycle of oil and gas wells, including planning, drilling, completion, production, and abandonment phases. It describes the planning process including well classification and formation pressure considerations. Key aspects of drilling are discussed such as rig types, crews, casing, and use of drilling mud to remove cuttings from the wellbore.

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

• Activities to plug wells permanently, remove surface
facilities, and restore the field as per initial state
3. Exploration
Once the Oil Company is granted a permit to conduct the
business from the government (through host authority),
they must start with exploration.
Exploration is an activities to detect oil & gas presence
beneath the earth surface by means of gravity survey,
magnetic survey, and seismic reflection survey.
Seismic surveys work on the principle of the time it takes
for reflected sound waves to travel through matter
(rock/soil) of varying densities and then translated into a
for reflected sound waves to travel through matter
(rock/soil) of varying densities and then translated into a
profile of the earth soil & rock layers, sometimes called
seismic imaging.
In offshore, seismic survey is done by a seismic vessel.
Finally, when an indication of oil & gas presence
(prospect) exists based on the evaluation, it must be
followed by a “drilling” activity to conclusively determine
the presence or absence of oil & gas inside the reservoir
(a subsurface “pool” where fluids trapped between layer
of soils & rocks).
6. Drilling
Drilling is activities to create a hole from the earth surface to the
reservoir target in the earth subsurface.
Based on the purposes, drilling can be divided into :
Exploration : to find the oil & gas reservoir
Appraisal : to further confirm the reservoir volume and characteristic
Development : to produce oil & gas from the reservoir
Injection : to inject fluids (gas,water,chemical,etc) into the reservoir
A set of machines for drilling is called drilling rig.A set of machines for drilling is called drilling rig.
Based on the structure housing the drilling equipment set,
offshore drilling rig can be classified into :
1. Bottom supported
Self-contained platform rig
Tender Assisted Drilling (TAD) rig
Jack Up (JU) rig
Inland barge (swamp-barge) rig
2. Floating
Semi-submersible rig
Drill ship
9. Development
Once significant hydrocarbon volume is confirmed, field
development plan / Plan of Development (FDP/PoD) will
be proposed to monetize the oil & gas deposit.
FDP shall contain :
Method of oil & gas volume calculation including
uncertainties
Method of hydrocarbon recovery and estimated recovered
volume (number of oil & gas that can be lifted through out

Surface facilities to extract, process, and export oil & gas
Operation and Maintenance philosophy
Cost, Schedule, and Economic calculation
Abandonment Plan
FDP is subject to host authority (government appointed
body for upstream oil & gas regulation) and shareholders
approval
10. Surface Facilities Definition
In offshore oil & gas industry, term “Surface” is defined
above the mud-line, or simply seabed / ocean floor /
bottom sea (including several meter below seabed).
Surface Facilities can be defined as a set of systems
and equipments to extract, process, and export oil &
gas in a safe, controlled, and efficient way which aregas in a safe, controlled, and efficient way which are
located on the surface.
Generally, surface facilities consists of 2 sections :
Substructure : a steel structure to support the upper part
(called topside) including the foundations.
Topside : an integral part of steel deck (can be single or
stacked) and all equipment placed on it, supported by a
substructure.
12. Substructure Types
In general, substructure can be divided into :
1. Fixed Type (bottom supported the seabed)
Jacket
Compliant Tower
Jack UpJack Up
Gravity Based Structure
2. Floating Type (float on the sea surface)
Mono/Single Hull
Semi Submersible (Semi Sub)
Tension Leg Platform (TLP)
SPAR
13. Fixed Substructure - Jacket
Welded tubular space frame with near vertical legs with bracing system between
legs. Piles will be inserted inside legs, hence the tubular frame will act like a “jacket”
covering piles. Jacket can have 3 up to 12 legs, but majority is 4 legs. Jacket is the
most common offshore substructure. The deepest jacket is Shell Bullwinkle at 412
m water depth on US Gulf of Mexico / GoM.
14. Fixed Substructure - Compliant
Flexible (compliant) tubular space frame with flexible elements to mitigate natural
forces. This tower can be free standing or supported by guy wires. The deepest
installation is Chevron Petronius (US GoM) at 623 m below sea level.
15. Fixed Substructure – Jack Up
Movable floating hull and three or more legs, which can be moved up and down
relative to hull. For operational mode, legs must be lowered to the seabed, then
raising the hull to the required elevation. Water depth for jack up installation depends
on the legs length, but normally below 100 m. Jack up can be easily moved and is
normally used on a marginal / small field with short production life (below 5 years),
sometimes also called MOPU (Mobile Offshore Production Unit).
16. Fixed Substructure – Gravity Based
Fixed structures that are held-in-place by its own weight plus any contained ballast,
majority constructed from steel-reinforced concrete, normally called CONDEEP
(concrete deep water structure), majority installed in Norway. The deepest structure
is Statoil Troll-A (Norway North Sea) at 303 m water depth.
17. Floating Structure – Monohull
Monohull is a type of vessel with only one hull. The hull may be in the form of normal
vessel (ship-shaped) or cylindrical (circular like a bowl) secured by sets of moorings
and anchors. It can have a liquid storage, hydrocarbon processing, and liquid
transfer to tanker capability, hence called FPSO (Floating Production Storage
Offloading). If no processing facility, it is called FSO (Floating Storage Offloading).
The deepest one is FPSO Stones (US GoM) at 2896 m water depth.
18. Floating Structure – Semi Sub
Semi submersible is floating structures with several columns (vertical hull) and
pontoons (horizontal hull) which can be controlled in such a way that pontoons
become fully submerged and column partially submerged, while the topside remains
above the water line, and secured with spread moorings and anchors. This will
increase the stability and station keeping. Semi sub platform sometimes called sFPS
(semi-sub Floating Production Station), FPS, or FPU (Floating Production Unit). The
deepest FPS is Chevron Jack/St. Malo (US GoM) at 2134 m water depth.
19. Floating Structure – Tension Leg Platform
TLP is a floating structure, normally in the form of semi-submersible, which is
vertically moored to anchors by a set of tubular steels called tendons. The tendons is
constantly in tension by floating structure buoyancy and tensioner system. The
tension leg keeps the platform very stable, hence surface wellhead can be installed.
The deepest TLP is Chevron Big Foot (US GoM) at 1581 m water depth.
20. Floating Structure – SPAR
SPAR is floating platform with a deep-draft (most of the section is submerged) large
vertical cylinder hull, completed with heavy ballast on the bottom to ensure center of
gravity is below center of buoyancy, secured with spread moorings and anchors. The
deep-draft design makes it very stable and suitable for surface wellhead. SPAR can
also store liquid. The deepest SPAR is Shell Perdido (US GoM) at 2450 water depth.
22. Surface Facilities Function
Surface facilities function can be described as :
Extraction : Facilities to extract oil & gas from the reservoir
into surface in a safe and controlled manner.
Processing : Facilities to process “raw oil & gas / well
stream” into “treated” crude oil and/or natural gas as per
customer requirement.
Exporting : Facilities to export treated/processed oil and/orExporting : Facilities to export treated/processed oil and/or
gas to customer receiving point.
In offshore platforms, those functions are done by :
Extraction : Wellhead Platform (WHP)
Processing : Central Processing Platform (CPP)
Exporting : Pipeline, F(P)SO, FLNG
In addition, Living Quarter is provided to accommodate
operation & maintenance crew 24/7.
23. Wellhead Function
Wellhead : A termination point of a well (a series of tubular
steel running from the surface up to certain target on the
reservoir, referred as the bottom hole) on the surface that
provides the structural and pressure-containing interface
for the drilling and production equipment.
During drilling, surface pressure control is provided by a
Blow Out Preventer (BOP).
Once drilling completed, surface pressure control isOnce drilling completed, surface pressure control is
replaced by a “Christmas Tree” installed on top of the
wellhead, with isolation and choke valves to control the
flow of well fluids during production.
Normally, wellhead & Christmas tree is located on the
platform and can be easily operated by man, called surface
wellhead or dry tree.
However, for deep water or when platform installation is
considered not cost-effective, wellhead & Christmas tree
may be located on the seabed, called subsea wellhead or
wet tree.
26. Processing Function
Not like many people think that “oil & gas” reservoir contains
only oil and/or gas, actually it always contain oil, gas, water, and
sometimes other contaminants like nitrogen (N2), carbon dioxide
(CO2), hydrogen sulfide (H2S), mercury (Hg), and salt.
Oil & gas molecules are actually constructed from the same
elements, Hydrogen (H) and Carbon (C), hence referred as
Hydrocarbon. Oil is hydrocarbon mixtures which form liquid at
room temperature (25oC), whereas gas is hydrocarbon mixtures
which form gas at room temperature.which form gas at room temperature.
Well fluids coming from the reservoir are actually a mixture of all
above fluids in a high pressure and temperature.
Meanwhile, the customers (downstream industry) require
separate treated oil (crude oil) & gas (natural gas) for further
processing.
Processing function is to separate oil, gas, and water, then treat
oil and gas to meet customer specification, and treat water for
overboard discharge (release to the sea) or re-inject to the
reservoir.

it can travel in a long distance to customer receiving point
Oil Metering : to measure the volume of oil export
Produced Water Treatment : to remove oil, gas, and other contaminants from
produced water until meeting certain criteria for disposal to the sea
29. Utility System

Pipeline is a long pipe for conveying fluids (oil and/or gas) .
Offshore pipeline will be placed on the seabed.
Offshore pipeline may be insulated to keep fluids warm andOffshore pipeline may be insulated to keep fluids warm and
coated with concrete to add stability and protection.
If oil pipeline is considered too expensive or no available

FPSO, or subsea storage, then stored oil exported to oil
shuttle tanker.
Same case for gas, offshore gas storage may be
considered using Floating Liquefied Natural Gas (FLNG),
then stored liquefied gas exported to LNG shuttle tanker.
