Utsira High
Utsira High no, Utsirahøgda is a basement high and horst in the southwest of the Norwegian continental shelf. It lies east of the Viking Graben and west of the Stord and Egersund basins 190 km west of Stavanger. It was on the Balder oil field at the flank of the Utsira High that oil was first discovered in Norway in 1967. The basement is of Utsira High is composed of granite that formed in Ordovician times. Parts of these granites contain saprolite and saprock that formed from weathering above sea level during the Early Mesozoic. before they became buried in Late Jurassic and Early Cretaceous-aged sandstone. These weathered rocks may be unconventional petroleum reservoirs. The strandflat at Bømlo island is considered a sedimentary rock Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Utsira Formation 01
Utsira () is the smallest municipality in Norway. The island municipality is located in northwestern Rogaland county, just off the western coast of Norway. Utsira is part of the traditional district of Haugaland. The municipality consists of the main island of Utsira as well as several small, uninhabited outlying islands. Utsira is located in the North Sea, about west of the town of Haugesund. All of the 206 residents () live on the main island of Utsira, where the administrative centre and Utsira Church are located. The municipality is the 355th largest by area out of the 356 municipalities in Norway, making it the second smallest municipality in Norway after the nearby island municipality of Kvitsøy. Utsira is the 356th most populous municipality in Norway with a population of 188, making it the smallest municipality in Norway by population. The municipality's population density is and its population has decreased by 13.8% over the previous 10-year period. Gene ...

Saprock
Saprolite is a chemically weathered rock. Saprolites form in the lower zones of soil profiles and represent deep weathering of the bedrock surface. In most outcrops its color comes from ferric compounds. Deeply weathered profiles are widespread on the continental landmasses between latitudes 35°N and 35°S. Conditions for the formation of deeply weathered regolith include a topographically moderate relief flat enough to prevent erosion and to allow leaching of the products of chemical weathering. A second condition is long periods of tectonic stability; tectonic activity and climate change can cause erosion. The third condition is humid tropical to temperate climate. Poorly weathered saprolite grit aquifers are capable of producing groundwater, often suitable for livestock. Deep weathering causes the formation of many secondary and supergene ores – bauxite, iron ores, saprolitic gold, supergene copper, uranium and heavy minerals in residual accumulations.

Petroleum In Norway
Petroleum, also known as crude oil, or simply oil, is a naturally occurring yellowish-black liquid mixture of mainly hydrocarbons, and is found in geological formations. The name ''petroleum'' covers both naturally occurring unprocessed crude oil and petroleum products that consist of refined crude oil. A fossil fuel, petroleum is formed when large quantities of dead organisms, mostly zooplankton and algae, are buried underneath sedimentary rock and subjected to both prolonged heat and pressure. Petroleum is primarily recovered by oil drilling. Drilling is carried out after studies of structural geology, sedimentary basin analysis, and reservoir characterisation. Recent developments in technologies have also led to exploitation of other unconventional reserves such as oil sands and oil shale. Once extracted, oil is refined and separated, most easily by distillation, into innumerable products for direct use or use in manufacturing. Products include fuels such as gasoline (pet ...

Geology Of The North Sea
The geology of the North Sea describes the geological features such as channels, trenches, and ridges today and the geological history, plate tectonics, and geological events that created them. The basement of the North Sea was formed in an intraplate setting during the Precambrian. Rigid blocks were overlaid with various depositions, sands and salts. These rigid blocks were transformed to a metamorphic base due to tectonic processes such as continental collisions which cause horizontal pressure, friction and distortion in the Caledonian plate cycle as well as the Variscan plate cycle. The blocks were also subjected to metamorphic evolution during the Triassic and Jurassic periods when the rock was heated up by the intrusion of hot molten rock called magma from the Earth's interior. The Caledonian (Iapetus) plate cycle saw the formation of the Iapetus suture during the Caledonian orogeny. The Iapetus suture was a major weakness creating a volcanic fault in the central North Se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geology Of Norway
The geology of Norway encompasses the history of Earth that can be interpreted by rock types found in Norway, and the associated sedimentological history of soils and rock types. The Norwegian mountains were formed around 400 million years ago (Ma) during the Caledonian orogeny. Precambrian Rocks of Archean age in Norway are confined to a few 10 km-scale areas within younger metamorphic belts exposed on islands off the west coast of northern Norway and as smaller fragments locally in the Western Gneiss Region in south-central Norway. Despite intense reworking during the Caledonian orogeny in some areas, three major belts can be recognised in the Proterozoic rocks of Norway, the Neoproterozoic and Mesoproterozoic Gothian and Sveconorwegian, the Palaeoproterozoic Svecokarelian and the intervening Transscandinavian Igneous Belt of late Palaeoproterozoic age. About 1400 million years ago in the Mesoproterozoic tectonic extension and continental magmatism led to the formatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basement Highs
A basement or cellar is one or more floors of a building that are completely or partly below the ground floor. It generally is used as a utility space for a building, where such items as the furnace, water heater, breaker panel or fuse box, car park, and air-conditioning system are located; so also are amenities such as the electrical system and cable television distribution point. In cities with high property prices, such as London, basements are often fitted out to a high standard and used as living space. In British English, the word ''basement'' is usually used for underground floors of, for example, department stores. The word is usually used with houses when the space below the ground floor is habitable, with windows and (usually) its own access. The word ''cellar'' applies to the whole underground level or to any large underground room. A ''subcellar'' is a cellar that lies further underneath. Purpose, geography, and history A basement can be used in almost e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
