What’s Petroleum? petr ra , which means rock and from Greek The word Petroleum comes from Latin Latin pet oleum , which means oil oil . It is also called crude oil , a naturally occ occurring urring oily oily,, bit b itumino uminous us liquid liquid compose composed d of various organic organ ic chemicals. chemicals. It is found in large quantit qu antities ies below the surface su rface of Earth and is used as a fuel and as a raw material in the chemical industry. Modern industrial societies use it primarily to achieve a degree of mobility—on land, at sea, and in the air—that was barely imaginable less than 100 years ago. In addition, petroleum petroleum and its derivativ derivatives es are used u sed in the manufacture of medici medicines nes and an d fertilizers, foodstuffs, plastics, building materials, paints, and cloth and to generate electricity. © 1993-2003 Microsoft Microsoft Corporation.

(F). Notice Notice the Key Discov Discoveri eries es at the the end. end. History of the Oil and Gas Industries
i. Since the earliest recorded recorded history history there there have been been accoun accounts ts of crude oil oil and natural gas seeping seeping to to the the earth's earth's surface ii. ii. Oil was used to to caulk boats boats and buildin buildings, gs, gre grease ase whee wheels ls and dress dress wounds wounds of anim animals and peop people le - but was rare rarely used as fuel because becaus e of of the foul smelling smelling fumes fumes iii. iii. Bette Better-qu r-qualit ality y crude crude oil seeps seeps provide provided d lamp fuel in in some parts of the middle middle east east iv. iv. Natural gas gas fed fed the cele celebrate brated d "perpe "perpettual tire tires" s" at Delphi Delphi in Greece, Greece, Baku on the Caspian Cas pian Sea and a nd other other mysti mystical cal sites sites in the ancient world v. In the the 3rd cent century ury AD, Chinese Chinese people people transporte transported d gas in bamboo ba mboo to to light temples. temples. They They also gas heat to to extract extract salt from brine.
vi. Coal gasification was invented by a Flemish chemist in 1609. Coal gas first lit the streets of London, England in 1807. vii. Discoveries of oil and gas became more common in the 18th and 19th centuries as people dug deeper wells in search of water viii. "Rock oil" or petroleum was once a popular patent medicine in Canada and the United States ix. Safer natural gas was first used for street lighting as early as 1821 when it was piped through hollow logs to Fredonia, New York x. However. natural gas was not widely used until the end of the 19th century when better drilling techniques and less leaky pipes were developed xi. The demand for better lighting led directly to the first widespread use of crude oil. By the 1850’s, the best available lamp oil was selling for US$2.50 per gallon ($0.66 per liter) xii. “Colonel” Edwin Drake found a practical way to produce large quantities of oil when he used a cable-tool drilling rig to tap an oil reservoir at Oil City, Pennsylvania in 1859 xiii. By that time oil was already being produced from hand dug wells in Canada and Eastern Europe, but Drake's drilled well unleashed the first "oil boom". It is often sited as the beginning of the modem oil era. xiv. Initial development around the world over the next four decades focused on the making and selling oil kerosene for lighting xv. The development of the internal combustion engine late in the 19th century transformed society and changed the nature of the oil and gas industry. xvi. The diesel engine, invented In 1892, became popular for industrial machinery and ships in the early 1900’s xvii. In 1911, Winston Churchill made a crucial decision to switch Britain’s Imperial Navy from coal to oil xviii. The First World War, 1914-1918, established oil as a key strategic commodity. Horses and trains gave way to tanks, trucks, airplanes, motorcycles and automobiles -all powered by gasoline. xix. Oil also played a dominant role in the Second World War - armies in North Africa, Europe and the Soviet Union were crippled when their oil supplies were interrupted - lack of oil helped end the dominance of the Japanese Navy in the Pacific - fuel shortages weakened German forces near the conclusion of the war - the first large petrochemical plants during the war to produce synthetic rubber

PETROLEUM FORMATION Petroleum is formed under the Earth’s surface by the decomposition of marine organisms. The remains of tiny organisms that live in the sea—and, to a lesser extent, those of land organisms that are carried down to the sea in rivers and of plants that grow on the ocean bottoms—are enmeshed with the fine sands and silts that settle to the bottom in quiet sea basins. Such deposits, which are rich in organic materials, become the source rocks for the generation of crude oil. The process began many millions of years ago with the development of abundant life, and it continues to this day. The sediments grow thicker and sink into the seafloor under their own weight. As additional deposits pile up, the pressure on the ones below increases several thousand times, and the temperature rises by several hundred degrees. The mud and sand harden into shale and sandstone; carbonate precipitates and skeletal shells harden into limestone; and the remains of the dead organisms are transformed into crude oil and natural gas. Once the petroleum forms, it flows upward in Earth’s surface through a well because it has a lower density than the brines that saturate the interstices of the shales, sands, and carbonate rocks that constitute the crust of Earth. The crude oil and natural gas rise into the microscopic pores of the coarser sediments lying above. Frequently, the rising material encounters an impermeable shale or dense layer of rock that prevents further migration; the oil has become trapped, and a reservoir of petroleum is formed. A significant amount of the upward-migrating oil, however, does not encounter impermeable rock but instead flows out at the surface of Earth or onto the ocean floor.

18- READING Increasing recoverable reserves Increasing recoverable reserves in the mature fields is not easy. In certain reservoir (such as Bloque IV of the giant Bachaquero field in Lake Maracaibo, Venezuela) horizontal wells can offer an effective method to increase recovery. In order to evaluate the potential for strategically placed horizontal wells to increase recovery, Maraven S.A. Schlumberger teamed up to conduct a study in a pilot area of the central part of the Bloque IV. Using wire line logs, cores, seismic data, fluid samples and the combined production and pressure histories, the interdisciplinary team constructed a reservoir model which was used to identify regions that would yield additional recovery by redevelopment with horizontal wells. The team selected the location of the first horizontal well in the field, which was drilled following a novel approach involving 3-D geosteering techniques. The article focuses on the methodology followed by the geoscientists, their findings and proposals to maximize oil recovery from the field.

20 - READING Read and make a summary (in teams). We know now that reservoirs can be very complex, fragmented pieces and blocks or permeable rock, all of which have enormous potential for containing oil and gas. Some may be very skinny reservoirs, some may be flat like pancakes, some may be fragmented. All of these different characters of reservoirs have vital amounts of oil and gas that we want to produce. There are some areas of the world where oil and/or gas have been centralized, accumulated. The Middle East, perhaps, can be called the land of the giants where oil fields can be eighty kilometers long, the reservoir body could be a thousand meters thick and with all of that, fields of oil these are significant volumes of world reserves. We have reservoirs that are shallow as a thousand feet and we have reservoirs in Texas that are down at 30 000 feet. We have reservoirs that are perhaps one million years old and others that are exciding six hundred million years of age so that a variety of rocks and history, properties, internal character takes place.

22- READING Read this text and do the exercises below: The Earth looks weird below the surface. How can geologists fill in this picture using remote sensing from the surface? There are several kinds of remote sensing. Each works by extending the eyes of the geoscientists into the earth. Surveys of anomalies and gravity can reveal rock bodies that may trap oil. Similar maps of magnetic anomalies, like this one of Alaska, taken from an airplane can also reveal oil traps. Likewise, shallow structures can be discerned with ground penetrating radar. But perhaps the most powerful tool is the seismic survey, which uses echoes to map rock layers as far down as four miles. These surveys peek the big picture but miss the details. Still, these techniques generally find structures that may contain oil; they usually don’t detect oil directly. 2

6- READING The stages of drilling Wells are normally drilled in stages, starting with a surface hole drilled to reach a depth anywhere from 400 to 600 meters, depending on final well depth and area conditions. The crew then pulls out the drill string and inserts steel pipe, called surface casing, which is cemented in place, to keep the wall from caving in. It controls the return flow of mud and other fluids encountered during drilling and also prevent contamination of groundwater. The beginning of the actual drilling, which takes place after the surface hole is drilled, is called spudding in. After setting surface casing and installing the blowout preventers (BOPs), the crew resumes drilling. A probe for shallow gas or heavy oil in eastern Alberta or Saskatchewan may require only two or three days to drill 450 metres through soft shales and sandstone to the target depth. However, a rig may work eight months or longer to penetrate 4,500 metres or more through hard, complex rocks in the foothills of the Rockies. When the bit needs to be replaced because of wear or changing rock strata, the crew has to pull out the entire string, unscrewing sections of pipe in single, double or triple sections, depending on the height of the derrick, and stacking them upright in the derrick. Then, they have to put the whole string back into the hole again, with the new bit in place. This process, which can be very laborious and time-consuming for a deep hole, is called tripping. Major improvements in the durability of bits and the formulation of drilling fluids since the 1980s have greatly reduced the number of trips required to drill a well. Many shallow wells today are drilled without a bit change. If the string breaks or gets stuck in the hole, a specialist is called in to help the crew go fishing with special tools. No one wants to lose an expensive bit and bottom-hole assembly, but the blocked hole is the real problem. As a last resort, the crew drills a curved section called a sidetrack to bypass the debris. After reading the text carefully, do the following activities.

Exploratory Well Acidizing Kelly Drillstem Test Spudding In Blowout
Definitions A type of pipe that is used for encasing a smaller diameter carrier pipe for installation in a well The first and sturdiest joint of the drill string in conventional rotary drilling rigs; thick-walled, hollow steel forging with four flat sides that fits into a square hole in the rotary table. A well drilled in or adjacent to a proven part of a pool to optimize petroleum production. The hoisting mechanism on a drilling rig which spools off or takes in the drilling line and thus raises or lowers the drill string and bit. A well drilled both in search of a new and as yet undiscovered accumulation of oil and gas, or in an attempt to significantly extend the limits of a known reservoir. Steel pipe sections, approximately 9 meters long, that are screwed together to form a continuous pipe extending from the drilling rig to the drilling bit at the bottom of the hole. Rotation of the drill pipe and bit causes the bit to bore
35
through the rock. Equipment that is installed at the wellhead to control pressures and fluids during drilling, completion and certain remedial operations to restore production. A method of sampling fluid from a formation using a tool attached to the drillstem; the sample is used to assess the type and volume of fluids in the formation as well as their pressure and rate of flow. A continuous cylinder of rock, usually from five to 10 centimetres in diameter, cut from the bottom of a wellbore as a sample of an underground formation. Chips and small fragments of rock cut by the drill bit and brought to the surface by the flow of drilling mud. An object left in the well bore during drilling or workover operations that must be recovered or drilled around before work can proceed. The injection of acids under pressure into the rock formation to create channels that allow the hydrocarbons to flow more easily into the wellbore. An uncontrolled flow of gas, oil or other fluids from a well. The first string of casing put into a well; it is cemented into place and serves to shut out shallow water formations and as a foundation for well control. When fluids with a higher pressure than that exerted by the drilling mud enter the wellbore; this creates the potential for a well to blow out of control. Detailed depth-related records of certain significant details of an oil or gas well; usually obtained by lowering measurement instruments into a well. Beginning to drill a well. The process of removing the drill string from the hole to change the bit and running the drill string and new bit back into the hole.
9- READING Cuttings and cores Results from previous drilling provide important information for explorationists. When a well is drilled, small rack chips called cuttings are recovered from the drilling fluid. These are ground up and broken off by the drill bit as it cuts into the earth. Geologists, geochemists and palynologists, scientists who study pollen and small fossils - examine the cuttings to learn more about the age, chemistry, porosity, permeability and other properties of the subsurface rock formations. Larger, more continuous cylindrical rock samples, called cores, can also be cut using a special coring bit. Although coring adds to the cost of the well, laboratory analysis and visual examination of the core provide additional important details about the basin’s history, the composition and physical characteristics of the rock and any fluids within it.
36
Even if a well fails to encounter oil or gas in commercial quantities, it still provides valuable information about underground rocks and structures. This may allow explorationists to generate new prospects or to match up certain seismic patterns with corresponding rock formations, which can lead to success with the next well - or the one after that.

Air and underbalanced drilling Occasionally, wells are drilled without mud to increase penetration rates and to avoid sensitive rock formations coming into contact with water. In so-called air drilling, compressed air removes the cuttings. Drillers can also obtain many of the same benefits through underbalanced drilling - using mud lightened by the addition of nitrogen or other gas. Underbalanced drilling has become increasingly common in Western Canada because it minimizes damage to the producing reservoir. This is especially useful in clay formations. Clays can collapse into the wellbore or swell if fresh water-based drilling fluids are used. Underbalanced drilling minimizes the invasion of the drilling fluid into the reservoir and allows oil and gas to be produced more effectively. Read and then do the following activities. I. Answer these questions.
a) When is mud not used in the drilling process? b) What, then, removes the cuttings? What is this process called? c) What is underballanced drilling? d) Are clays useful in this process? Why? e) What else can underballanced drilling do? II. Match the words with the correct definition.

Compartments in the reservoir. Analysis of the areal and vertical production pattern and pressure profiles shows that the Lower Lagunillas reservoir of Bloque IV is highly compartmentalized. It comprises a number of distinct reservoirs in different fault blocks that produce from several layers separated by shale barriers, some of which are partially sealing. Thus, the production behaviour of individual wells is highly variable, depending on the compartment and the layer being drained by the well. Bubble plot of the cumulative production from Bloque IV reveals that most of the production comes from the central part of the field and from a small area in the north of the pilot area. This area of anomalously high gas-free oil production, compared to wells on either side of it, results from faults recently delineated by a 3-D seismic survey. The fault for the west of this area is apparently a barrier which renders the gas injection in the northern wells ineffective for the pressure maintenance of the central and southern parts of the field. Abnormally high quantities of gas have been produced from some wells in the southern part of the field in the vicinity of the major faults Pueblo Viejo and VCL-70, suggesting that these wells are draining from separate compartments. I. - Say True (T) or False (F). Explain the false statements. ____ There is a good continuity in the Lower Lagunillas Reservoir of Bloque IV. ____ All of the shale barriers are totally impermeable.

Dynamics in the Lower Lagunillas Reservoir. The unexpected proliferation of free gas and water in the high–permeability zones and the declining production from the Lower Lagunillas reservoir of Bloque IV, motivated the operator to seek a better understanding of the reservoir and to evaluate the potential to increase ultimate recovery and offtake rate by drilling horizontal wells. To quantify the potential benefits of field redevelopment, Maraven selected a pilot area and, jointly with Schlumberger formed an interdisciplinary team of geoscientists to study this area. The first step involved reviewing the production history and pressure response of the field during the past 37 years. After the successful completion of the first producer, the field was developed rapidly by drilling additional wells during 1958 and 1959. Production rose rapidly and peaked in November 1959 at 225,000 BOPD from 86 wells. Between 1960 and 1963, the production declined rapidly due to gas encroachment from the north and subsequent closing of wells in this sector. In order to maintain the reservoir pressure, the operator started a gas injection program in 1965. The rate of pressure decline slowed to 7-8% annually in 1974, but this was due to shut-down of the field’s northern sector and to aquifer support in the south. The gas injection program has been only partially effective and both pressure and production rates have shown continuous decline during the last 30 years. In October 1989, the production rate jumped to 39,800 BOPD as a result of acidization and improvement in the lifting method. So far, approximately 45% of the original oil in place (OOIP) has been recovered and an extra 13% of OOIP is thought to remain as recoverable reserves. Current production from the field is 18,000 BOPD with a field gas-oil ratio of 1235 scf/ stb and a water cut of 20%.

Background: fossil fuels- a short science lesson Natural gas, crude oil and coal are called fossil fuels. Like the fossils we see in museums, fossil fuels originated as life forms millions of years ago. The energy in fossil fuels began as solar energy. Plants use sunlight and chlorophyll in the process of photosynthesis to convert water and carbon dioxide into sugars, starches, fats and proteins- the building blocks of life. The remains of primitive plants and animals have been transformed over millions of years by heat, pressure, water flows, or biological and chemical reactions. This process results in compounds of hydrogen and carbon known as hydrocarbons trapped underground. Fossil hydrocarbons are generally classified according to their physical state at room temperature natural gas is obviously a gas. Crude oil is liquid. Bitumen is viscous or semi-solid type of petroleum. Coal is solid. Chemically natural consists of molecules with more hydrogen than carbon atoms. The main constituent of natural gas is the simplest hydrocarbon, Methane (CH4), a molecu1e of one carbon atom and --- hydrogen atoms. Crude oil and bitumen are generally made up of larger more complex molecules with more carbon atoms. Depending on density and molecular weight, pelro1eUI11 hydrocarbons are often described as “light” or ”heavy”. Hydrocarbons seldom occur in pure forms. Methane, for example, may be found in coal seams, oil reservoirs, and in mixtures with hydrogen sulphide., carbon dioxide or other hydrocarbons known as natural gas liquids. Oil and gas production containing hydrogen sulphide (H2S) is called sour, while production with little or no sulphur content is termed sweet. Most oil and gas requires some processing to remove substances such as hydrogen sulphide, water, carbon dioxide and to separate the naturally occurring mixtures into the various marketable commodities. Field gathering pipelines carry oil and gas from wells to processing facilities, although some oil is transported by truck. Field processing facilities are called batteries, while gas is processed at gas plants. Some bitumen and heavy oil goes to upgraders, which alter its chemical composition to produce a marketable commodity called. The natural gas coming from a gas plant can be used “as is” by the final consumer (although an odorant, mercaptan is added for safety reasons in distribution systems).Crude oil and bitumen require further processing under

Alkylation and Catalytic Cracking Two additional basic processes,
waxes by a process called fractional distillation. During the process, the parts, or fractions, of crude oil are divided out successively by their increasing molecular weight. For instance, gasoline has a low molecular weight and vaporizes at a fairly low temperature. This means that at the appropriate temperature, while all of the rest of the oil is still in liquid form, gasoline may be separated out. The remaining oil goes through the same process at a slightly higher temperature, and jet fuel is divided out. Repeating the distillation

alkylation and catalytic cracking, were introduced in the 1930s and further increased the gasoline yield from a barrel of crude oil. In alkylation small molecules produced by thermal cracking are recombined in the presence of a catalyst. This produces branched molecules in the gasoline boiling range that have superior properties—for example, higher antiknock ratings—as a fuel for high-powered engines such as those used in today’s commercial planes.

4- Reading. Pollution Problems In its early days, the oil industry generated considerable environmental pollution. Through the years, however, under the dual influences of improved technology and more stringent regulations, it has become much cleaner. The effluents from refineries have decreased greatly and, although well blowouts still occur, new technology has tended to make them relatively rare. The policing of the oceans, on the other hand, is much more difficult. Oceangoing ships are still a major source of oil spills. In 1990 the Congress of the United States passed legislation requiring tankers to be double hulled by the end of the decade. Another source of pollution connected with the oil industry is the sulfur in crude oil. Regulations of national and local governments restrict the amount of sulfur dioxide that can be discharged by factories and utilities burning fuel oil. Because removing sulfur is expensive, however, regulations still allow some sulfur dioxide to be discharged into the air. Many scientists believe that another potential environmental problem from refining and burning large amounts of oil and other fossil fuels (such as coal and natural gas) occurs when carbon dioxide (a by-product of the burning of fossil fuels), methane (which exists in natural gas and is also a by-product of refining petroleum), and other by-product gases accumulate in the atmosphere. These gases are known as greenhouse gases, because they trap some of the energy from the Sun that penetrates Earth’s atmosphere. This energy, trapped in the form of heat, maintains Earth at a temperature that is hospitable to life. Certain amounts of greenhouse gases occur naturally in the
58
atmosphere. However, the immense quantities of petroleum, coal, and other fossil fuels burned during the world’s rapid industrialization over the last 200 years are a contributing source of higher levels of carbon dioxide in the atmosphere. During that time period, these levels have increased by about 28 percent. This increase in atmospheric carbon dioxide, coupled with the continuing loss of the world’s forests (which absorb carbon dioxide), has led many scientists to predict a rise in global temperature. This increase in global temperature might disrupt weather patterns, disrupt ocean currents, lead to more violent storms, and create other environmental problems. In 1992 representatives of over 150 countries convened in Rio de Janeiro, Brazil, and agreed on the need to reduce the world’s emissions of greenhouse gases. In 1997 world delegations again convened, this time in Kyōto, Japan. During the Kyōto meeting, representatives of 160 nations, including the United States, signed an agreement known as the Kyōto Protocol, which would require 38 industrialized nations to limit emissions of greenhouse gases to levels that are an average of 5 percent below the emission levels of 1990. In order to reduce their fossil fuel emissions to achieve these levels, the industrialized nations would have to shift their energy mix toward energy sources that do not produce as much carbon dioxide, such as natural gas, or to alternative energy sources, such as hydroelectric energy, solar energy, wind energy, or nuclear energy. While the governments of some industrialized nations have ratified the Kyōto Protocol, others have not. A major blow to the protocol came in March 2001 when United States president George W. Bush rejected it, saying it would damage the U.S. economy. Under the previous administration of President Bill Clinton, the United States had volunteered to reduce greenhouse gas emissions to 7 percent below 1990 levels. Bush’s rejection meant that the world’s largest consumer of fossil fuels would not participate in the Kyōto Protocol Vocabulary:

Team Work II- Translate some of the definitions 6- Reading The wonderful distilling process by which we get petroleum products. (…)The manufacture of all these petroleum products illustrates the marvels of modern industrial chemistry. In its simplest form the production of the principal product, gasoline, consists of heating the crude -oil mixture to the point where it gives off vapors just as boiling water gives oil steam. The lightest hydrocarbon molecules vaporize first, and when the vapor is passed through cooled pipes it condenses to form gasoline. As the temperature of the crude oil is raised by stages the other, heavier, hydrocarbon molecules are vaporized in the order of their volatility (Lightness), and are condensed by cooling to form other products: kerosene, gas oil, lubricating oil and fuel oil. This is called straight-run refining, or fractional distillation. About 1915, with the demand for motor fuel rapidly increasing, petroleum refiners began to use a new process-"cracking". Cracking is a good name for the process. After the straight-run refining, the heavier products (gas oil and fuel oil) are put under high pressure and very great heat is applied until the heavy molecules split, or crack, into lighter ones. Gasoline and other products the separated out of the cracked oil by a process similar to straight-run refining. Cracking has practically doubled the amount of gasoline obtainable from a forty- two gallon barrel of crude oil. Today a barrel of crude oil yields nearly a half-barrel of gasoline. During the cracking process, gases are generated which formerly were wasted or used as fuel in the refinery. Now these gases can be turned into gasoline by polymerization. This is almost the reverse of cracking. Instead of splitting heavy molecules into 62
lighter ones, polymerization takes the light gas molecules and synthesizes them (welds them together). This creates the more complex molecules of gasoline. In this way more gasoline can be obtained from a barrel of crude oil (…) I- Answer the following questions according to the text:

7- Reading Pretreatment and Distillation Petroleum in the unrefined state is of limited value and of limited use. Refining is required to obtain products that are attractive to the marketplace. Thus petroleum refining is a series of steps by which the crude oil is converted into salable products with the desired qualities and in the amounts dictated by the market. Modern petroleum refineries are much more complex operations than refineries of the early 1900s and even of the years immediately following World War II Early refineries were predominantly distillation units, perhaps with ancillary units to remove objectionable odors from the various product streams. The refinery of the 1930s was somewhat more complex but was essentially a distillation unit. At this time cracking and coking units were starting to appear in the scheme of refinery operations. These units were not what we imagine today as a cracking and coking unit but were the forerunners of today's units. Also at this time, asphalt was becoming a recognized petroleum product. Finally, current refineries are a result of major evolutionary trends and are highly complex operations. Most of the evolutionary adjustments to refineries have occurred during the decades since the commencement of World War II. In the petroleum industry, as in many other industries, supply and demand are key factors in efficient and economic operation. Innovation is also a key. 6
A refinery is an integrated group of manufacturing plants that vary in number with the variety of products. Refinery processes must be selected and products manufactured to give a balanced operation; that is, crude oil must be converted into products according to the rate of sale of each. For example, the manufacture of products from the lower boiling portion of petroleum automatically produces a certain amount of higher boiling components. If the latter cannot be sold as, say, heavy fuel oil, they accumulate until refinery storage facilities are full. To prevent the occurrence of such a situation, the refinery must be flexible and able to change operations as needed. This usually means more processes to accommodate the everchanging demands of the market. This could be reflected by the inclusion of a cracking process to change an excess of heavy fuel oil into more gasoline, with coke as the residual product, or the inclusion of a vacuum distillation process to separate the heavy oil into lubricating oil stocks and asphalt. Thus, to accommodate the sudden changes in market demand, a refinery must include the following: 1. All necessary nonprocessing facilities 2. Adequate tank capacity for storing crude oil, intermediate, and finished products 3. A dependable source of electrical power 4. Material-handling equipment 5. Workshops and supplies for maintaining a continuous 24 hours a day, 7 days a week operation 6. Waste disposal and water-treating equipment 7. Product-blending facilities 8. Petroleum refining as we know it is a very recent science, and many innovations evolved during the twentieth century. The first processes are focused on the cleanup of the feedstock, particularly the removal of the troublesome brine constituents. This is followed by distillation to remove the volatile constituents with the concurrent production of a residuum that can be used as a cracking (coking) feedstock or as a precursor to asphalt. In the case of tar sand bitumen, the distillation step is unnecessary because of the low amount of feedstock that would be volatile under distillation conditions. Current methods of bitumen processing involve direct use of the bitumen as feedstock for delayed or fluid coking.

Tanker near the Port of New York
Petroleum____________ worldwide by___________ such as this one near the Port of New York. Most modern tanker ships are supertankers that ___________ more than 450 m (1500 ft) long and carry over 200,000 _________ (220,000 short tons) of oil. List: metric tons / tanker ships/ is transported / measure/. 3. READING Most oil fields are a considerable distance from the refineries that convert crude oil into usable products, and therefore the oil must be transported in pipelines and tankers. However, most crude oil needs some form of treatment near the reservoir before it can be carried considerable distances through the pipelines or in the tankers. Railroad cars and motor vehic1es are also used to a large extent for the transportation of petroleum products. (paragraph.1) Fluids produced from a well are seldom pure crude oil.
In
fact, the oil often contains
quantities of gas, saltwater, or even sand. Separation must be achieved before transportation. Separation and c1eaning usually take place at a central facility that collects the oil produced from several wells. Gas can be separated conveniently at the wellhead. When the pressure of the gas in the crude oil as it comes out at the surface is not too great, a simple flow tank can be used to separate the gas from the oil at atmospheric pressure. If a considerable amount of gas is present, particularly if the crude oil is under considerable pressure, a series of flow tanks is necessary.
7
The natural gas itself may contain as impurities one or more nonhydrocarbon substances. The most abundant of these impurities is hydrogen sulfide, which imparts a noticeable odor to the gas. A small amount of this compound is considered advantageous as it gives an indication of leaks and where they occur, as mentioned. (paragraph.2) Another step that needs to be taken in the preparation of crude oil for transportation is the removal of excessive quantities of water. Crude oil at the wellhead usually contains emulsified water in proportions that may reach amounts approaching 80-90%. It is generally required that crude oil to be transported by pipeline contain substantially less water than may appear in the crude at the wellhead. In fact, water contents from 0.5 to 2.0% have been specified as the maximum tolerable amount in a crude oil to be moved by pipeline. It is therefore necessary to remove the excess water from the crude oil before transportation. (Paragraph 3) The transportation of crude oil may be further simplified by blending crude oils from several wells, thereby homogenizing the feedstock to the refinery. It is usual practice, however, to blend crude oils of similar characteristics although fluctuations in the properties of the individual crude oils may cause significant variations in the properties of the blend over a period of time. However, the technique of blending several crude oils before transportation, or even after transportation but before refining, may eliminate the frequent need to change the processing conditions that would perhaps be required to process each of the crude oils individually.(p.4) Large-scale transportation of crude oil, refined petroleum products, and natural gas is usually accomplished by pipelines and tankers, while smaller-scale distribution, especially of petroleum products, is carried out by barges, trucks, and rail tank cars. In fact, the transportation from the source of the crude oil to the market is as old as the industry itself. (p.5) In more modern times, the transportation of crude oil from fields to refineries and of products to market centers was at one time essentially dependent upon rail transportation. By the early 1970s, the use of railroad tank cars had diminished to the point at which only a little over 1 % of the total petroleum tonnage was hauled 71
by the railroads. Pipeline mileage increased to become the major means of transportation. (p.6) Pipelines may be used to transport different types of crude oil (batch transportation). When the different batches must be kept separated to prevent mixing, slugs of kerosene, water, or occasionally inflatable rubber balls are used to separate the batches. However, there is also the possibility that the batches can be transported through the pipelines without such separators. The properties of each batch may be such that mixing, other than to form a narrow interface, is prevented. It is frequently necessary to pass cylindrical steel cleaners (pigs) through the pipelines, between pumping stations, to maintain the pipeline clear of deposits. (p.7) Tank trucks are used for both lock and intermediate hauling from manufacturing and distance hauling from manufacturing and terminal points to individual domestic, commercial, and industrial consumers that maintain storage tanks on their premises. Because of costs, most bulk deliveries by truck fall within a radius of 300 miles. Seagoing tankers, on the other hand, can be sent to any destination where a port can accommodate them and can be shifted to different routes according to need. (p.8) The seagoing tanker fleets that are owned, or used, by the world’s oil companies are also responsible for the movement of a considerable portion of the world’s crude oil. In fact, seagoing tankers form one of the most characteristic features associated with the transportation of petroleum. Many of these ships are of such a size that there are few ports that can handle them. Instead these large ships (VLCCs, very large crude carriers, and ULCCs, ultra large crude carriers) spend their time sailing the seas between different points, filling up and off-loading without ever entering port. Special loading jetties, artificial islands, or large buoys moored far offshore have been developed to load or off-load these tankers. In general, the larger the tanker the lower its unit cost of transportation. (p.9) One other aspect of transportation is the shipment of bitumen (or the whole oil sand or even bitumen-enriched oil sand, produced by, say, a less efficient once-through hot water separation) in trucks or trains. Currently, economic constraints related to the amount of material that would have to be moved to enable even a nominal conversion or upgrading operating to run continuously (hazards of weather and
72
mechanical constraints notwithstanding) have caused these types of operation to be downgraded in priority. (p.10) Natural gas presents different transportation requirements problems.
Because of its lower density natural gas is much more expensive to ship than crude oil. Most natural gas moves by pipeline, but in the late 1960s tanker shipment of cryogenically liquefied natural gas (LNG) began, particularly from the producing nations in the Pacific to Japan. Special alloys are required to prevent the tanks from becoming brittle at the low temperatures (-161°C, - 258°F) required to keep the gas liquid. (p.10) Thus, the means by which natural gas is transported depends upon several factors: l.
the physical characteristics of the gas to be transported, whether in the gaseous or the liquid phase;
2.
the distance over which the gas will be moved;
3.
such features as the geological and geographic characteristics of the terrain, inc1uding land and sea operations;
4.

This has arisen mainly because of the tendency for petroleum and natural gas companies to expand their exploration programs to the sea. Lines are now laid in marine locations where depths exceed 500 feet and cover distances of several hundred miles to the shore. Excellent examples of such operations inc1ude the drilling operations in the Texas gulf and in the North Sea. (p.11) Natural gas is also transported by seagoing vessels. The gas is either transported under pressure at ambient temperatures (e.g., propane and butanes) or at atmospheric pressure but with the cargo under refrigeration (e.g., liquefied petroleum gas). For safety reasons, petroleum tankers are constructed with several independent tanks so that rupture of one tank will not necessarily drain the whole 73
ship, unless it is a severe bow-to-stem (or stem-to-bow) rupture. Similarly, gas tankers also contain several separate tanks. (p.12)

In what way? 4- READING Pipelines are the safest, most efficient and least expensive means of overland energy transportation. Most pipelines are out of sight, buried a metre or more below the surface. These steel arteries are a vital component of a nation’s transportation system, comparable to the networks of roads, railways, ports, air services and electrical transmission lines. Unlike other modes of transportation, pipelines represent a very large up- front investment. Capital costs include pipe, related facilities, construction and right-of – way acquisition. Pipeline construction and operation generate billions of dollars of economic activity in Canada annually. Pipelines are also a significant source of tax revenue. When new oil or gas is found, producers and pipe liners start looking for the most economical way to deliver the commodity to market. This task is complicated by several factors. The ultimate size and lifespan of newly discovered oil and gas reserves can not be known with certainty. Subsequent discoveries elsewhere may be able to supply the market more economically. Investors and regulators demand some assurance that sufficient reserves exist to supply any pipeline during the time needed to pay off the capital cost of
75
construction. Natural gas pipelines have high capital costs but relatively low operating costs. Oil pipelines have lower capital costs but somewhat higher operating costs. Once the pipeline route and volume have been determined, engineers must decide on the size of pipe and amount of horsepower. A large-diameter pipe is expensive to install but comparatively cheap to operate it can operate at lower pressure, with less friction and a smaller energy requirement for pumping or compression. With more compression or horsepower at pumping stations or compressor stations, smaller pipes can be used, but the system will be more costly to operate. These same decisions arise if additional capacity is needed later. More pipes can be laid or more horsepower can be added. The decision depends on such factors as energy costs, environmental impacts, safety, steel prices and financing costs. Taken front Petroleum Communication Foundation (CPI).

6- OIL STORAGE
Every facility involved in the production of petroleum and related products requires some type of storage. The arrival of large quantities of petroleum oil at import and refining centers has brought about the need for storage facilities. The usual form of crude oil storage is the collection of large cylindrical steel storage tanks (tank farm) that are a familiar sight at most refineries and shipping terminals. The tanks vary in size, but some are capable of holding up to 950,000 barrels of oil. Crude oil may also be stored in such geological features as salt domes.
77
The domes have been previously leached or hollowed out into huge underground caves, such as those used by the U.S. Strategic Petroleum Reserve in Louisiana and Texas. Other underground storage facilities inc1ude disused coal mines and artificial caverns. Natural gas is, on occasion, stored in old reservoirs from which the gas has been recovered. The gas is pumped under pressure into the reservoir at times of low gas demand so that it can be retrieved later to meet peak demand. During the early days of oil production, the method of storing was almost exclusively white-pine wooden tanks, which were followed by cypress tanks, and then redwood tanks. However, because of the constant and steep rise in the cost of redwood lumber and the diminution of skilled erectors required, the installation of new wooden tanks is nearly nonexistent. The bolted-steel tank was developed next and virtually replaced the wooden tank. Types of tanks for oil storing.
Bolted-Steel Tanks
Bolted tanks are designed and furnished as segmental elements assembled on location to provide complete vertical, cylindrical, aboveground, closed- and open-top steel storage tanks. Standard API bolted tanks are available in nominal capacities of 100 to 10,000 bbl, and are designed for approximately atmospheric internal pressures. Bo1ted tanks offer the advantage of being easily transported to desired locations and erected by hand. To meet changing requirements for capacity of storage, bolted tanks can be easi1y dismantled and re-erected at new locations. If a tank develops a hole from corrosion or becomes damaged, a single sheet or more may be replaced. A complete tan k bottom may be replaced in the field without dismantling the tank. Also, a section may be removed from the tank, a new connection installed in the sheet, and the section replaced without danger. No special equipment (cranes, etc.) is required for the erection of bolted tanks. These tanks are erected by nonspecialized crews using hand tools and usually an impact wrench. Bolted tanks are available with painted, galvanized, and special coatings, including factory-baked coatings. Painting on both sides of the sheets during fabrication gives the inside of the tank some corrosion protection. Galvanizing the sheets and all tank parts by the "hot-dip" process or applying a factory-baked coating affords high corrosion protection.
78
Generally, bolted tanks are fabricated from 12- or l0-gauge steel and, if not galvanized or furnished with a protective coating for corrosion protection, they do not have the expected life of the welded-steel tanks, which are usually constructed of heavier steel.
Welded-Stee1 Tanks
Shop-fabricated welded, cylindrical-shape tanks are available in a large variety of sizes as shop-fabricated items... Shop-welded tanks provide the oil production industry with tanks of adequate safety and reasonable economy for use in the storage of crude petroleum and other liquids commonly handled and stored by the production segment of the industry. The heavier steel also affords a corrosion allowance. Shop fabrication permits testing in the shop for leaks and also provides immediate storage. Tanks are merely up-ended from a truck on the location.
Flat-Sided Tanks (Non-API)
Although cylindrical-shape tanks may be structurally best for tank construction, rectangular tanks frequently are preferred. When space is limited, such as offshore, requirements favour flat-sided tank construction because several cells of flat-sided tanks can be fabricated easily and arranged in less space than other types of tanks. Flat-sided or rectangular tanks normally are used as atmospheric type storage.
Field-Welded Tanks
Field-welded tanks provide large storage capacities in a single unit. These fieldwelded tanks are of heavier gauge steel with a minimum thickness of 1/4 inch for the tank bottom and 3/16 in. for the shell and deck. Larger field-welded tanks providing storage capacities of 150,000 bbl or more have become quite prevalent for use in the storage of oil and petroleum products. Field welded tanks, particularly those larger than 10,000 bbl, frequently are designed and erected in accordance with API Standard 650. This standard covers material, design, fabrication, erection, and testing requirements for welded steel storage tanks. It also includes an alternative basis for shell design, as well as one for calculating tank-shell thickness. The API Standard 650 also may be used to govern the design and fabrication of the smaller shop welded tanks.
79
Fixed Roof
Fixed roofs are permanently attached to the tank shell. Welded tanks of 500-bbl capacity and larger may be provided with a frangible roof (designed for safety release of the welded deck-to-shell joint in the event excess internal pressure occurs). In this case, the design pressure should not exceed the equivalent pressure of the dead weight of the roof including rafters, if external. Floating Roof Storage tanks may be furnished with floating roofs where, by the tank roof floats on the stored contents. This tank’s type is used primarily for storage near atmospheric pressure. Floating roofs are designed to move vertically within the tank shell to provide a constant minimum void between the surface of the stored product and the roof. Floating roofs normally are designed to provide a constant seal 00tween the periphery of the floating roof and the tan k shell. They can be fabricated in a type that is exposed to the weather or a type that is under a fixed roof. Internal floating-roof tanks, with an external fixed roof, are used in areas of heavy snowfall since accumulations of snow or water on the floating roof affect the operating buoyancy. These can be installed in existing tanks as well as new tanks. Both floating roofs and internal floating roofs are used to reduce vapor losses and to aid in conservation programs. Fig. 11.3 is a schematic of a typical internal floating-roof tank.

Internal floating-roof tanks, with an external fixed roof, are used in areas of heavy snowfall since accumulations of snow or water on the floating roof affect the operating buoyancy. These can be installed in existing tanks as well as new tanks. Both floating roofs and internal floating roofs are used to reduce vapor losses and to aid in conservation programs.
Cone-Bottom Tanks
The cone bottom in either the bolted or the welded tank offers a means of draining and removing water, or watercut oil, from only the bottom of the tank, leaving the marketable oil above. The drain line from a sump-equipped cone bottom must be equipped with a vortex breaker to drain off most of the water without coning oil into the drain. With a flat-bottom tank, some of the marketable oil must be removed if all the water is removed from the tank. Corrosion on the tan k bottom is kept to a minimum by keeping all water removed. A cone bottom can be kept clean without having to open the tank if 1 or 2 bbl are drained off once or twice weekly and pumped back through the treating system. If this is not done and the bottom solidifies, the tank must be opened. The conebottom tank can be cleaned without entering. A water hose, handled just outside the cleanout opening, can be used to flush the solids to the center of the cone and drain connection.
Pipe Storage
Pipe that is used specifically for storing and handling liquid petroleum components should be designed and constructed in accordance with applicable codes. Pipe storage consists of any number of sections of line pipe laid parallel to each other and interconnected to operate as a single unit. The size and length depend on the capacity required and economics. The exterior of buried-pipe storage should be coated and wrapped for corrosion protection. It also is recommended that any coated, wrapped, and buried carbon steel pipe be protected cathodically against the possibility of eventual holidays (imperfections) in the coating.
Underground Storage
Underground storage is most advantageous when large volumes are to be stored. Underground storage is especially advantageous for high-vapor-pressure products. Solution-mined and conventionally mined caverns are not typically used for underground storage of refrigerated products Underground storage allows most of the surface area (except for the entry wells) to be used for other purposes. This is 81
