Frigg Gas Field
Frigg gas field is a natural gas field on Norwegian block 25/1 in the North Sea, on the boundary between the United Kingdom and Norway. The field is named after the goddess Frigg. King Olav V of Norway officially opened production on 8 May 1978. Production was closed on 26 October 2004. The field is situated northwest of Stavanger. Operator for the field was the French oil company Elf Aquitaine, which merged and changed name to Total S.A. Operations were regulated according to an agreement between the UK and Norwegian governments called the Frigg Treaty. Infrastructural changes were made in three phases: * Phase I - 1977 * Phase II - 1978 * Phase III - 1981 Geology The field was discovered at a depth of by the Petronord group (Elf Aquitaine, Total Oil Marine Norsk, and Norsk Hydro) and the Norwegian State in 1971 with Well 25/1-1 using the Semi-submersible Neptune P 81 in of water.Heritier et al, 1980, p. 60 The well was located following interpretation of a 15 by 20 km ...

North Sea
The North Sea lies between Great Britain, Norway, Denmark, Germany, the Netherlands and Belgium. An epeiric sea, 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 energy, 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 Viking Age, Vikings' rise. The Hanseatic League, the Dutch Golden Age, Dutch Republic, and the Kingdom of Grea ...

Structural Basin
A structural basin is a large-scale structural formation of rock strata formed by tectonic warping of previously flat-lying strata. They are geological depressions, the inverse of domes. Elongated structural basins are also known as synclines. Some are sedimentary basins, aggregations of sediment that filled up a depression or accumulated in an area. Others were formed by tectonic events long after the sedimentary layers were deposited. Basins may appear on a geologic map as roughly circular or elliptical, with concentric layers. Because the strata dip toward the center, the exposed strata in a basin are progressively younger from the outside in, with the youngest rocks in the center. Basins are often large in areal extent, often hundreds of kilometers across. Structural basins are often important sources of coal, petroleum, and groundwater. Examples Europe * Hampshire Basin, United Kingdom * London Basin, United Kingdom * Paris Basin, France * Permian Basin, Poland, no ...

Natural Gas Fields In Norway
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Soc ...

Norwegian Petroleum Museum
The Norwegian Petroleum Museum (''Norsk Oljemuseum'') is located in Stavanger, Norway. Overview It was designed by the architectural firm of Lunde & Løvseth Arkitekter A/S and was opened on 20 May 1999. Seen from the sea the museum looks like a small oil platform. The unusual architecture has made the museum a landmark in the Port of Stavanger. The museum was built in stone, glass and concrete and covers approx. 5,000 square meters. The museum focuses on offshore petroleum activity especially in the North Sea. The museum displays objects, films, photographs and other materials have been collected that document Norwegian oil and gas activities. The museum shows the technological development from the beginning of the Norwegian oil history in the mid-1960s, from the first North Sea drilling platforms, through steel and concrete platforms developed and built in Norway, to modern, flexible production ships and subsea systems.

Vesterled
Vesterled is a natural gas pipeline system, which runs from the Heimdal field ( Heimdal Riser platform) in the North Sea to St Fergus Gas Plant near Peterhead in Scotland. The name ''Vesterled'' is the term used by the Vikings for their westward voyages, i.e. ''vesterled'' = "the way westward". History Originally the Vesterled pipeline was known as the Frigg Norwegian Pipeline, which was built in 1974–1978 to transport gas from the Frigg field to the United Kingdom. It was laid in parallel to the Frigg UK Pipeline creating the Frigg Transportation System. It became operational in August 1978. As the Frigg field was running to cease production, the spur line from the Heimdal field was put in operation on 1 October 2001. Technical description The pipeline is long and has a diameter of . The Vesterled pipeline consists of two sections: a long pipeline links the Heimdal Riser with the former Frigg Norwegian Pipeline. The capacity of Vesterled is about 12 billi ...

Frigg UK System
The Frigg UK System is a natural gas transportation system from the North Sea gas fields to St. Fergus near Peterhead in Scotland. It transports natural gas from the Alwyn North, Dunbar, Ellon, Grant, Nuggets, Frigg, Bruce, Ross, Captain, Buzzard, Tartan, Piper, Chanter, Galley, Hamish, Highlander, Ivanhoe, MacCulloch, Petronella, Saltire, and Rob Roy, fields. History Construction of the main pipeline, the Frigg UK pipeline, started in 1974 and was completed in 1977. It was built to transport natural gas from the Frigg gas field to the United Kingdom. Because of technical limitations, it was decided to build two parallel pipelines, one (the Frigg UK pipeline) by the United Kingdom and one by Norway (former Frigg Norwegian Pipeline, now Vesterled). Even in British waters, until 1998 both pipelines were in Norwegian jurisdiction. Technical description The system comprises the Frigg UK pipeline, Alwyn pipeline, other connection lines, and processing facilities at the St Fergus ...

Density
Density (volumetric mass density or specific mass) is the substance's mass per unit of volume. The symbol most often used for density is ''ρ'' (the lower case Greek letter rho), although the Latin letter ''D'' can also be used. Mathematically, density is defined as mass divided by volume: : \rho = \frac where ''ρ'' is the density, ''m'' is the mass, and ''V'' is the volume. In some cases (for instance, in the United States oil and gas industry), density is loosely defined as its weight per unit volume, although this is scientifically inaccurate – this quantity is more specifically called specific weight. For a pure substance the density has the same numerical value as its mass concentration. Different materials usually have different densities, and density may be relevant to buoyancy, purity and packaging. Osmium and iridium are the densest known elements at standard conditions for temperature and pressure. To simplify comparisons of density across different s ...

Flat Spot
A flat spot, or wheel flat, also called spalling or shelling, is a fault in railroad wheel shape. A flat spot occurs when a rail vehicle's wheelset is dragged along the rail after the wheel/axle has stopped rotating. Flat spots are usually caused by use of the emergency brake, or slip and slide conditions that causes wheels to lock up while the train is still moving. Flat spots are more common in the autumn and winter when the rails are slippery. Flat spots can also be caused by faulty brakes or wheelset bearings. Consequences If the flat spot is very small, the rail vehicle will be able to continue being used. The fault is removed later in the wheelset turning process, using a wheel lathe. However, because of the heat suffered while being dragged along the rail and the impacts suffered afterward, these wheels are more likely to break due to changes in the alloy structure. If the flat spot is very large (as in the picture), strands of molten metal may have stuck on one sid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anticline
In structural geology, an anticline is a type of fold that is an arch-like shape and has its oldest beds at its core, whereas a syncline is the inverse of an anticline. A typical anticline is convex up in which the hinge or crest is the location where the curvature is greatest, and the limbs are the sides of the fold that dip away from the hinge. Anticlines can be recognized and differentiated from antiforms by a sequence of rock layers that become progressively older toward the center of the fold. Therefore, if age relationships between various rock strata are unknown, the term antiform should be used. The progressing age of the rock strata towards the core and uplifted center, are the trademark indications for evidence of anticlines on a geologic map. These formations occur because anticlinal ridges typically develop above thrust faults during crustal deformations. The uplifted core of the fold causes compression of strata that preferentially erodes to a deeper ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
