Schiehallion Oilfield
The Schiehallion oilfield is a deepwater offshore oilfield approximately west of the Shetland Islands in the North Atlantic Ocean. The Schiehallion and adjacent Loyal field were jointly developed by BP on behalf of the Schiehallion field partners; BP, Shell, Amerada Hess, Murphy Oil, Statoil and OMV, and the Loyal field partners; BP and Shell. The Schiehallion field, together with Foinaven, Clair, Lancaster and Solan fields, forms the frontier area generally termed as the ''West of Shetland''. Field development Schiehallion field was discovered in 1993 by the semi-submersible drilling vessel ''Ocean Alliance'' while drilling the third exploration well in block 204 (well 204-3). The field is located in blocks 204/20 and 204/25 of the United Kingdom Continental Shelf in a water depth of . Recoverable oil reserves of Schiehallion are estimated to be between . Schiehallion is named after a mountain in the highlands. During 1994 and 1995 an appraisal of Schiehallion and Lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Sea
The North Sea lies between Great Britain, Norway, Denmark, Germany, the Netherlands and Belgium. An epeiric sea on the European continental shelf, it connects to the Atlantic Ocean through the English Channel in the south and the Norwegian Sea in the north. It is more than long and wide, covering . It hosts key north European shipping lanes and is a major fishery. The coast is a popular destination for recreation and tourism in bordering countries, and a rich source of energy resources, including wind and wave power. The North Sea has featured prominently in geopolitical and military affairs, particularly in Northern Europe, from the Middle Ages to the modern era. It was also important globally through the power northern Europeans projected worldwide during much of the Middle Ages and into the modern era. The North Sea was the centre of the Vikings' rise. The Hanseatic League, the Dutch Republic, and the British each sought to gain command of the North Sea and access t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Magnus Oilfield
The Magnus oilfield is a large oilfield in the United Kingdom's zone of North Sea. It is located north-east of the Shetland Islands. The field is located mainly in Block 211/12a. Resources are estimated to total of oil, of which are recoverable reserves. History The Magnus oilfield was discovered in March 1974 by BP. The discovery was made below the seabed in the younger sands of the Late Jurassic by the semi-submersible drilling rig Sedco 703. Similarly to several other fields in the area, the field was named after the Viking saint– Magnus of Orkney. It was announced on 24 January 2017 that BP will sell a 25% share of the field and turn over the operatorship to EnQuest. Fabrication of the Magnus structure began in 1973 at Highland Fabricators' yard at Nigg Bay in the Cromarty Firth. The jacket of the Magnus platform, the main oil export pipeline to the Ninian Central Platform, and the Northern Leg Gas Pipeline to Brent A were installed by 1974. In May 1996, t ...

Enhanced Oil Recovery
Enhanced oil recovery (abbreviated EOR), also called tertiary recovery, is the extraction of crude oil from an oil field that cannot be extracted otherwise. EOR can extract 30% to 60% or more of a reservoir's oil, compared to 20% to 40% using primary and secondary recovery. According to the US Department of Energy, carbon dioxide and water are injected along with one of three EOR techniques: thermal injection, gas injection, and chemical injection. More advanced, speculative EOR techniques are sometimes called quaternary recovery. Methods There are three primary techniques of EOR: gas injection, thermal injection, and chemical injection. Gas injection, which uses gases such as natural gas, nitrogen, or carbon dioxide (CO2), accounts for nearly 60 percent of EOR production in the United States. Thermal injection, which involves the introduction of heat, accounts for 40 percent of EOR production in the United States, with most of it occurring in California. Chemical injection, ...

Liquefied Petroleum Gas
Liquefied petroleum gas (LPG or LP gas) is a fuel gas which contains a flammable mixture of hydrocarbon gases, specifically propane, propylene, butylene, isobutane and n-butane. LPG is used as a fuel gas in heating appliances, cooking equipment, and vehicles. It is increasingly used as an aerosol propellant and a refrigerant, replacing chlorofluorocarbons in an effort to reduce damage to the ozone layer. When specifically used as a vehicle fuel, it is often referred to as autogas or even just as gas. Varieties of LPG that are bought and sold include mixes that are mostly propane (), mostly butane (), and, most commonly, mixes including both propane and butane. In the northern hemisphere winter, the mixes contain more propane, while in summer, they contain more butane. In the United States, mainly two grades of LPG are sold: commercial propane and HD-5. These specifications are published by the Gas Processors Association (GPA) and the American Society of Testing and Ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

West Of Shetland Pipeline
The West of Shetland Pipeline (WOSP) is a pipeline system which transports natural gas from three offshore fields in the West of Shetland area to Sullom Voe Terminal in the Shetland Isles of Scotland. West of Shetland area The West of Shetland area is a region in the northern Atlantic Ocean, where there are currently three developed offshore fields; Schiehallion, Foinaven and Clair. A number of further hydrocarbon discoveries have been made in the area, but these are not currently considered to be economic due to the high costs of development. The Laggan-Tormore and Rosebank-Lochnagar discoveries are in the process of being further appraised for development, but the WOSP is considered to be unable to carry the additional gas production from these fields. Ownership WOSP is owned collectively by the owners of the Schiehallion, Loyal, Foinaven and East Foinaven fields; each owner company holds divided capacity rights in accordance with its ownership interest. It is operated by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dynamic Positioning
Dynamic positioning (DP) is a computer-controlled system to automatically maintain a vessel's position and heading by using its own propellers and thrusters. Position reference sensors, combined with wind sensors, motion sensors and gyrocompasses, provide information to the computer pertaining to the vessel's position and the magnitude and direction of environmental forces affecting its position. Examples of vessel types that employ DP include ships and semi-submersible mobile offshore drilling units (MODU), oceanographic research vessels, cable layer ships and cruise ships. The computer program contains a mathematical model of the vessel that includes information pertaining to the wind and current drag of the vessel and the location of the thrusters. This knowledge, combined with the sensor information, allows the computer to calculate the required steering angle and thruster output for each thruster. This allows operations at sea where mooring or anchoring is not feasible du ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sullom Voe Terminal
The Sullom Voe Terminal is an oil and gas terminal at Sullom Voe in the Shetland Islands of Scotland. It handles production from oilfields in the North Sea and East Shetland Basin and stores oil before it is transported by tanker. Construction When Shetland was identified as a location to provide pipeline terminal and support facilities for offshore oil installations in the northern North Sea, corporations involved had expected to each build their own terminal facilities. However, wishing to minimize the negative impacts of the industry, the Shetland Islands Council, with power granted to it by the UK Parliament in the 1974 Zetland County Council Act, was able to contain all pipeline terminal facilities at the Sullom Voe site. Sullom Voe Terminal was built between 1975 and 1981. 6,000 people were employed during construction. They were housed in temporary accommodation, including the former car ferry . The first oil was received at 18:40 on 25 November 1978 via the Brent pip ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrocyclone
Hydrocyclones are a type of cyclonic separators that separate product phases mainly on basis of differences in gravity with aqueous solutions as the primary feed fluid. As opposed to dry or dust cyclones, which separate solids from gasses, hydrocyclones separate solids or different phase fluids from the bulk fluid. A hydrocyclone comprises a cylindrical shaped feed part with tangential feed; an overflow part with vortex finder; a conical part with an apex. A cyclone has no moving parts. Working principle Product is fed into the hydrocyclone tangentially under a certain pressure. This creates a centrifugal movement, pushing the heavier phase outward and downward alongside the wall of the conical part. The decreasing diameter in the conical part increases the speed and so enhances the separation. Finally, the concentrated solids are discharged through the apex. The vortex finder in the overflow part creates a fast rotating upward spiral movement of the fluid in the centre of the co ...

Produced Water
Produced water is a term used in the oil industry or geothermal industry to describe water that is produced as a byproduct during the extraction of Petroleum, oil and natural gas, or used as a medium for heat extraction. Produced water is the kind of brackish and saline water from underground formations that are brought to the surface. Oil and gas reservoirs often have water as well as hydrocarbons, sometimes in a zone that lies under the hydrocarbons, and sometimes in the same zone with the oil and gas. In geothermal plays, the produced water is usually hot. It contains steam with dissolved solutes and gases, providing important information on the geological, chemical, and hydrological characteristics of geothermal systems. Oil wells sometimes produce large volumes of water with the oil, while gas wells tend to produce water in smaller proportions. To achieve maximum Petroleum extraction, oil recovery, waterflooding is often implemented, in which water is Water injection (oil pro ...

Slugcatcher
Slug Catcher is the name of a unit in the gas refinery or petroleum industry in which slugs at the outlet of pipelines are collected or caught. A slug is a large quantity of gas or liquid that exists in the pipeline. Slugs Pipelines that transport both gas and liquids together, known as two-phase flow, can operate in a flow regime known as slugging flow or slug flow. Under the influence of gravity, liquids will tend to settle on the bottom of the pipeline, while the gases occupy the top section of the pipeline. Under certain operating conditions gas and liquid are not evenly distributed throughout the pipeline, but travel as large plugs with mostly liquids or mostly gases through the pipeline. These large plugs are called slugs. Slugs exiting the pipeline can overload the gas/liquid handling capacity of the plant at the pipeline outlet, as they are often produced at a much larger rate than the equipment is designed for. Slugs can be generated by different mechanisms in a pip ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
