CFD for Wind and Tidal Offshore Turbines

   Problems where the forces on rotating or oscillating bodies in a fluid are to be predicted are common in engineering applications and result in fluid-structure interaction situations. Examples are flows around isolated rotating bodies and foils, turbo machinery applications, insect flight aerodynamics, unmanned air vehicles and, more recently, flows through renewable energy devices, e.g. wind and tidal turbines. A particularly challenging problem is presented by cross-flow wind and tidal turbines for power generation. These types of turbine consist of foil shaped blades that generate lift forces so as to rotate a shaft to which the blades are connected. Therefore azimuthal changes in blade aerodynamics are common, resulting in complex flow phenomena such as stalled flows, vortex shedding and blade-vortex interactions. Cross-Row Turbines are sometimes referred to as vertical-axis turbines, however the term cross-flow turbine is preferred since the absolute turbine position is omitted and the relative flow-axis geometry is emphasised through this terminology. To date, this type of turbine configuration has had limited use within the wind energy sector, where the three bladed axial flow turbine has been widely adopted. However, it is thought that CFT configurations can be advantageous for new emergent markets as offshore wind and tidal energy production and also for installation in urban environments. A brief review of some of the arguments in favour and against this type of configuration follows. On the one hand, the main drawback is that CFT are generally less efficient than axial flow turbines since the downstream half of the turbine produces less torque due to the shadowing from the upstream blades. Furthermore, since for part of the cycle the blade moves parallel to the flow, the lift force powering the blades, being proportional to the incident flow speed squared, is reduced...

Phase Behaviour of Petroleum Reservoir Fluids

   The techniques of oil and gas recovery are under constant development. This is followed by an increased demand to the accuracy of PVT simulation results. High quality simulation results are dependent on accurate fluid compositions and PVT data. We wanted to cover experimental procedures in more detail in the second edition than in the first edition, so we asked our colleague. Jawad Azeem Shaikh, to be a coauthor. Jawad has 12 years of experience from a commercial PVT laboratory, and his experience includes sampling, compositional analyses, and measurements of both routine and EOR PVT data. Chapters 2 and 3 provide a comprehensive review of experimental procedures used to provide compositional data and PVT data. The oil industry sees the PC-SAFT equation as a possible alternative or replacement of cubic equations. The PC-SAFT equation is introduced in Chapter 4, and Chapter 5 on fluid characterization includes a section on the characterization of the PC-SAFT equation. Chapter 7 shows simulation results for PVT data obtained with the PC-SAFT equation. Chapter 9 on regression has a section on how to recreate the original reservoir fluid composition from a depleted gas condensate reservoir fluid sample. Chapter 12 on asphaltenes includes a section on how to simulate the location of a possible asphaltene tar mat. We have, since the first edition was published, had the opportunity to analyze numerous EOR PVT data and have used this experience to make a thorough update of Chapter 15 on MMP calculations. All other chapters are updated with new data material and new references.

Oil & Gas Pipelines in Nontechnical Language

   If some veteran natural gas pipeline operators moved over to an oil pipeline, they would scratch their heads in wonderment about the different variables, controls, customer requirements, and alarm bells. But aside from operations, oil and natural gas pipelines look essentially the same, perform the same service, and obey the same laws of physics. They are installed in largely the same manner and face the same regulatory and social dilemmas. But that does not mean they all use the same nomenclature. Such differences in nomenclatures can occur concerning natural gas pipelines versus oil pipelines, and crude oil pipelines versus refined products pipelines. Making life easier, operations of some types of pipelines are more or less indistinguishable from oil pipelines operations. These include chemical liquids pipelines, natural gas liquids (NGL) pipelines, and liquefied petroleum gas (LPG) pipelines. On the other side, pipelines that move anhydrous ammonia, carbon dioxide, and gaseous chemicals like ethylene operate much like natural gas pipelines...

Tubular String Characterization in High Temperature High Pressure Oil and Gas Wells

   In applied basic theory for deep well testing research, tubular string mechanical analysis is complex as fluid temperature and tubing pressure have a large effect on the force of the tubular string. When well testing, the methods used for determining the temperature and the pressure of the tubular string include measurements from thermometers and pressure gauges located in the tubing, temperature and pressure measurements at only the well bottom and well head. With these measurements, it is possible to predict the complete distribution using theory analysis technology. Predicting accurate temperature and pressure profiles in flowing wells can greatly enhance oil and gas production. However, for gas wells with High Temperature High Pressure (HTHP), it is often difficult to operate thermometers and pressure gauges within the tubing itself, and therefore theory analysis can be used as an effective and feasible method.cost and time.

Gas Production Operations

   Although natural gas has been utilized as a fuel for more than 150 years, the large demand for it has developed fairly recently. The principal reason for this is the greater difficulty of storing and transporting gas as compared to liquid fuels. Initially, natural gas was used only in the areas in which it was produced, with excess production being vented to the air or flared. This was especially true of gas produced along with the oil in oil fields. The development of large diameter, high pressure pipelines and compressors, along with the technology of gas storage in reservoirs, has spurred both the demand for natural gas and the development of the technology required to produce and transport it. This is illustrated in the United States by the fact that natural gas supplied more than 30% of the total energy demand in 1980 as compared to 18% in 1950 and less than 4% in 1920. Natural gas supplied about 20% of the energy worldwide in 1980. The increased demand has also gready increased the price obtained for the gas. In 1950 the average price for natural gas in the United States was about $0.07 per thousand standard cubic foot (Mscf), and as late as 1970 the price averaged only about $0.17/Mscf. In 1980 the average price had increased to more than $0.90/Mscf with gas in some areas selling for as much as $9.00/ Mscf. The large difference in the average and maximum selling price is due to the huge quantities being sold at very low prices under long term contracts made many years ago...

Arctic Offshore Engineering

   The Arctic is a region of endless fascination, beauty and excitement. Many writers more eloquent than we are have explored its biology, geography, history and environment. At the same time, it is the home of many people who want to pursue civilised and comfortable lives with the amenities of the 21s1 century. The Arctic seas and the lands bordering them are important to the wider human community as a source of raw materials, above all petroleum, but as well as for fish, timber and mineral ores, and important too for tourism and exploration. Many important reserves of petroleum have been found already, some of those reserves are in production, and the unexplored geology of this vast region has many promising structures: some estimates have it that as much as a third of the petroleum still to be discovered will be found in the Arctic. With that as one priority, we must not forget that the Arctic is uniquely vulnerable to damage: if we make a mess, the consequences will be with us for decades. Oil and gas reserves close to shore can be produced by horizontal drilling, but beyond a few kilometres the petroleum industry will need platforms to drill from and produce to, and pipelines and other systems to bring the petroleum ashore and transport it to markets. Those structures have to operate safely in an extremely demanding environment. The ocean is cold and rough, and for much of the year it will be covered with ice, often in very large pieces. Ice pushes against structures with great force, and drags along the seabed, strongly enough to cut huge gouges. Sometimes the seabed will be partly frozen, and anything we do may alter the thermal regime and thaw or freeze the seabed soil, greatly modifying its physical properties. Almost all the problems of offshore construction in lower latitudes are still present, and there are storm waves and high winds, tidal currents, shifting seabeds and the added challenge of long periods of winter darkness...

Deepwater Petroleum Exploration and Production - A Nontechnical Guide

   As with any foray into a new frontier, history and innovation have been happening almost every day since our first edition's publication date. As in the first edition, our first two chapters of the book will bring you from the first geologic toe-in-the-water in California more than hundred years ago to stepping off the Outer Continental Shelf of the Gulf of Mexico into thousands of feet of water. That journey is just the prelude to understanding present and even future deepwater operations. To complete the setting, this edition adds a new complete chapter on geology and geophysics. To pull this off, we asked four accomplished scientists in the field, Stephen Sears, Fred Keller, Tim Garfield, and Mike Forrest, all with decades of experience with large exploration and production (E&P) organizations, to contribute chapter 3. The processes for exploring, developing, and producing petroleum in the deepwater are about the same as for the shelf or, really, the onshore. From the outside, just four steps take place—explore, appraise, develop, and produce. From the inside, each of these processes takes many more steps, depending on how closely we look. And we look closer in chapters 4 through 13, even more closely than in the first edition. We have added other new chapters on the drilling rigs and service vessels used in the deepwater...

Offshore Operation Facilities - Equipment and Procedures

   After Dagang Oil Field was discovered in 1964, which was called Plant 641 at that time, the Chinese offshore oil industry started in 1965 when the Ministry of Petroleum Industry decided to "go to the sea." Although offshore oil began 70 years later in China than in the rest of the world, through decades of hard work, China's offshore oil and gas exploration and development has witnessed astonishing progress and thus has made great achievements that attract worldwide attention. China has discovered six big oil and gas basins in the 130*10 m2 offshore continental shelf of the Bohai Sea, South Yellow Sea, East China Sea, South Sea Pearl River Mouth, Yinggehai in Beibu Gulf, and the shallow water of Taiwan Strait. It is estimated that China has an abundance in offshore oil and gas resources with (150 ~ 200) x 10s t of oil resources and 14 x 1012 m3 of natural gas resources. By creating the Foreign Cooperative Exploitation of Offshore Petroleum Resources Act in 1982, China established China National Offshore Oil Corporation (CNOOC, for short). Against this backdrop, China's offshore oil industry took a new step. Over the past 20 years, China has been following the principle of foreign cooperation while maintaining independent management; at the same time, China has insisted on the innovation of systems and technology, as well as following the path of internationalized development. In terms of offshore oil and gas development and production, China has achieved continuously high-speed and high-efficiency performance. Oil production developed from an annual output of 8 x 104 t in 1982 to 4293 x 104 t in 2008 (equivalent to total oil and gas production in that year). Take the CNOOC as an example: Its gross assets reached CNY 428.5 billion with its net assets reaching CNY 291.6 billion, and its sales volume, gross profit, and taxes paid that year reached CNY 198.3 billion, 67.7 billion, and 56.9 billion, respectively. This made a significant contribution to the national economy...
