The Lun-A (Lunskoye-A) platform, located off the north eastern coast of Sakhalin Island and is a concrete gravity base substructure (CGBS).. An oil platform (also called an oil rig, offshore platform, oil production platform, etc.) is a large structure with facilities to extract and process petroleum and natural gas that lie in rock formations beneath the seabed.
The platform is located in the Perdido fold belt which is a rich discovery of crude oil and natural gas. The Perdido spar began production in 2010 and its peak production is 100,000 barrels of oil equivalent (c. 16 000 m 3 /d ) and 200 million cubic feet of gas per day (c. 5.7 × 10 6 m 3 /d ).
Spar Platform – Spar Platforms use a large cylinder to support the floating deck from the seafloor. On average, about 90% of the Spar Platform's structure is underwater. Most Spar Platforms are used up to depths of 1 kilometer (3,000 feet), but new technology can extend them to function up to 3,500 meters (11,500 feet) below the surface.
The Troll A platform is a Condeep gravity-based structure offshore natural gas platform in the Troll gas field off the west coast of Norway. Built from reinforced concrete , as of 2014 [update] , it was the tallest structure that has ever been moved to another position, relative to the surface of the Earth, and is among the largest and most ...
Byford Dolphin was a semi-submersible, column-stabilised drilling rig operated by Dolphin Drilling, a subsidiary of Fred Olsen Energy.Byford Dolphin was registered in Hamilton, Bermuda, [1] and drilled seasonally for various companies in the British, Danish, and Norwegian sectors of the North Sea.
Offshore oil well drilling platform, Continental Oil Co., Gulf of Mexico, 1955. Around 1891, the first submerged oil wells were drilled from platforms built on piles in the fresh waters of the Grand Lake St. Marys in Ohio. The wells were developed by small local companies such as Bryson, Riley Oil, German-American and Banker's Oil. [2]
Submarine pipelines are used primarily to carry oil or gas, but transportation of water is also important. [3] A distinction is sometimes made between a flowline and a pipeline. [ 1 ] [ 3 ] [ 4 ] The former is an intrafield pipeline, in the sense that it is used to connect subsea wellheads , manifolds and the platform within a particular ...
Oil and gas fields reside beneath many inland waters and offshore areas around the world, and in the oil and gas industry the term subsea relates to the exploration, drilling and development of oil and gas fields in these underwater locations. [1] Under water oil fields and facilities are generically referred to using a subsea prefix, such as ...
