Conductor Support System
On offshore oil platforms, conductor support systems, also known as conductor supported systems or satellite platforms, are small unmanned installations consisting of little more than a well bay, and a small process plant. They are designed to operate in conjunction with a static production platform which is connected to the platform by flow lines and/or by Umbilical cable. Traditionally, these jacket-type structures have been installed and used in shallow to medium water depths of up to 40 – 60 meters. The conductor supported system use its inherited strength of the well conductors to support both the wells and the topside structure. The conductor supported system is particularly suited to areas with more benign environmental conditions, however it is a common development option even in hurricane / cyclone prone areas such as the Gulf of Mexico or Australia's Carnarvon Basin. The well conductors act as both structural, weight-supporting piles and flowlines for the produced ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oil Platform
An oil platform (or oil rig, offshore platform, oil production platform, and similar terms) is a large structure with facilities to extract and process petroleum and natural gas that lie in rock formations beneath the seabed. Many oil platforms will also have facilities to accommodate the workers, although it is also common to have a separate accommodation platform bridge linked to the production platform. Most commonly, oil platforms engage in activities on the continental shelf, though they can also be used in lakes, inshore waters, and inland seas. Depending on the circumstances, the platform may be fixed Platform, fixed to the ocean floor, consist of an artificial island, or floating oil production system, float. In some arrangements the main facility may have storage facilities for the processed oil. Remote subsea wells may also be connected to a platform by flow lines and by umbilical cable, umbilical connections. These sub-sea facilities may include of one or more subsea ...

Well Bay
A well bay is an area of an oil platform where the Christmas trees and wellheads are located. It normally consists of two levels, a lower where the wellheads are accessed and an upper where the Xmas Trees are accessed often along with the various well control panels, which will have pressure gauges and controls for the hydraulically actuated valves, including downhole safety valve and annular safety valve. On a platform with a drilling package, the well bay will be located directly below it to facilitate access for drilling and well interventions. See also *Oil platform *Christmas tree A Christmas tree is a decorated tree, usually an evergreen conifer, such as a spruce, pine or fir, or an artificial tree of similar appearance, associated with the celebration of Christmas.

Umbilical Cable
An umbilical cable or umbilical is a cable and/or hose that supplies required consumables to an apparatus, like a rocket, or to a person, such as a diver or astronaut. It is named by analogy with an umbilical cord. An umbilical can, for example, supply air and power to a pressure suit or hydraulic power, electrical power and fiber optics to subsea equipment and divers. Spaceflight applications Rockets Umbilicals connect a missile or space vehicle to ground support equipment on the launch pad before launch. Cables carry electrical power, communications, and telemetry, and pipes or hoses carry liquid propellants, cryogenic fluids, and pressurizing and purge gases. These are automatically disconnected shortly before or at launch. Umbilical connections are also used between rocket stages, and between the rocket and its spacecraft payload; these umbilicals are disconnected as stages are disconnected and discarded. Space suits Early space suits used in Project Gemini in 1965 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apache Energy
The Apache () are a group of culturally related Native American tribes in the Southwestern United States, which include the Chiricahua, Jicarilla, Lipan, Mescalero, Mimbreño, Ndendahe (Bedonkohe or Mogollon and Nednhi or Carrizaleño and Janero), Salinero, Plains (Kataka or Semat or " Kiowa-Apache") and Western Apache ( Aravaipa, Pinaleño, Coyotero, Tonto). Distant cousins of the Apache are the Navajo, with whom they share the Southern Athabaskan languages. There are Apache communities in Oklahoma and Texas, and reservations in Arizona and New Mexico. Apache people have moved throughout the United States and elsewhere, including urban centers. The Apache Nations are politically autonomous, speak several different languages, and have distinct cultures. Historically, the Apache homelands have consisted of high mountains, sheltered and watered valleys, deep canyons, deserts, and the southern Great Plains, including areas in what is now Eastern Arizona, Northern Mexico ...

Carnarvon Basin
The Carnarvon Basin is a geological basin located in the north west of Western Australia which extends from the Dampier Archipelago to the Murchison bioregion, and is the main geological feature that makes up the North West Shelf The North West Shelf is a continental shelf region of Western Australia. It includes an extensive oil and gas region off the North West Australia coast in the Pilbara region. Geology Considerable parts of the region are the highest prospective .... The onshore part of the Carnarvon Basin covers about 115,000 km2 and the offshore part covers approximately 535,000 km2 with water depths up to 3,500 metres. It is separated into two major areas - the Northern Carnarvon Basin, and the Southern Carnarvon Basin.

Liquefied Natural Gas
Liquefied natural gas (LNG) is natural gas (predominantly methane, CH4, with some mixture of ethane, C2H6) that has been cooled down to liquid form for ease and safety of non-pressurized storage or transport. It takes up about 1/600th the volume of natural gas in the gaseous state (at standard conditions for temperature and pressure). LNG is odorless, colorless, non-toxic and non-corrosive. Hazards include flammability after vaporization into a gaseous state, freezing and asphyxia. The liquefaction process involves removal of certain components, such as dust, acid gases, helium, water, and heavy hydrocarbons, which could cause difficulty downstream. The natural gas is then condensed into a liquid at close to atmospheric pressure by cooling it to approximately ; maximum transport pressure is set at around ( gauge pressure), which is about one-fourth times atmospheric pressure at sea level. The gas extracted from underground hydrocarbon deposits contains a varying m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North West Shelf Venture
The North West Shelf Venture, situated in the north-west of Western Australia, is Australia's largest resource development project. It involves the extraction of petroleum (mostly natural gas and condensate) at offshore production platforms, onshore processing and export of liquefied natural gas, and production of natural gas for industrial, commercial and domestic use within the state. Project With investments totalling $25 billion since the early 1980s, the project is the largest resource development in Australian history. In the late 1980s, it was the largest engineering project in the world. The Venture is underpinned by huge hydrocarbon reserves within the Carnarvon Basin, with only about one-third of the Venture's estimated total reserves of of gas produced to date. It is owned by a joint venture of six partners BHP, BP, Chevron, Shell, Woodside Petroleum and a 50:50 joint venture between Mitsubishi and Mitsui & Co with each holding an equal one-sixth shareholding.
