An oil platform 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 to the ocean floor, consist of an artificial island, or 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 connections. These sub-sea facilities may include one or more subsea wells or manifold centres for multiple wells.
North Sea oil is a mixture of hydrocarbons, comprising liquid petroleum and natural gas, produced from petroleum reservoirs beneath the North Sea.
The Atlantis oil field is the third largest oil field in the Gulf of Mexico. The field was discovered in 1998 and is located at the Green Canyon blocks 699, 700, 742, 743, and 744 in United States federal waters in the Gulf of Mexico about 130 miles (210 km) from the coast of Louisiana. The oil field lies in water depths ranging from 4,400 to 7,100 feet. The subsea structure of Atlantis has long been the target of safety critics.

APA Corporation is the holding company for Apache Corporation, an American company engaged in hydrocarbon exploration. It is organized in Delaware and headquartered in Houston. The company is ranked 431st on the Fortune 500.
A blowout is the uncontrolled release of crude oil and/or natural gas from an oil well or gas well after pressure control systems have failed. Modern wells have blowout preventers intended to prevent such an occurrence. An accidental spark during a blowout can lead to a catastrophic oil or gas fire.
Offshore drilling is a mechanical process where a wellbore is drilled below the seabed. It is typically carried out in order to explore for and subsequently extract petroleum that lies in rock formations beneath the seabed. Most commonly, the term is used to describe drilling activities on the continental shelf, though the term can also be applied to drilling in lakes, inshore waters and inland seas.
Subsea technology involves fully submerged ocean equipment, operations, or applications, especially when some distance offshore, in deep ocean waters, or on the seabed. The term subsea is frequently used in connection with oceanography, marine or ocean engineering, ocean exploration, remotely operated vehicle (ROVs) autonomous underwater vehicles (AUVs), submarine communications or power cables, seafloor mineral mining, oil and gas, and offshore wind power.
Amethyst is a natural gas field in the Southern North Sea, about 30 miles (48 km) east of the Yorkshire coast. Gas lies in a Permian sandstone reservoir around 2,700 metres (8,900 ft) below the seabed. The gasfield is operated by BP.
Bill Barrett Corporation was an energy company based in Denver, Colorado. Its core business is natural gas and oil exploration and development in the Rocky Mountains region of the United States.
The Tiber Oil Field is a deepwater offshore oil field located in the Keathley Canyon block 102 of the United States sector of the Gulf of Mexico. The deepwater field was discovered in September 2009 and it is operated by BP. Described as a "giant" find, it is estimated to contain 4 to 6 billion barrels of oil in place. Although BP states it is too early to be sure of the size – a "huge" field is usually considered to contain 250 million barrels. It required the drilling of a 10,685 m (35,056 ft) deep well under 1,260 m (4,130 ft) of water, making it one of the deepest wells ever drilled at the time of discovery.

Atlas America, Inc., until its acquisition by Chevron in 2010, was a natural gas and oil extraction company based in suburban Pittsburgh, Pennsylvania in the United States. The corporation was also involved in the transportation of resources and features a pipeline division. The base of operations for the company was in the Appalachian shale deposits, as well as in similar ones in the Midwest. Natural gas was processed by the company in facilities in Oklahoma and Texas.
The Macondo Prospect is an oil and gas prospect in the United States Exclusive Economic Zone of the Gulf of Mexico, off the coast of Louisiana. The prospect was the site of the Deepwater Horizon drilling rig explosion in April 2010 that led to a major oil spill in the region from the first exploration well, named itself MC252-1, which had been designed to investigate the existence of the prospect.
Newfield Exploration Company was a petroleum, natural gas and natural gas liquids exploration and production company organized in Delaware and headquartered in Houston, Texas, USA. In February 2019, the company was acquired by Encana.
Helix Energy Solutions Inc., known as Cal Dive International prior to 2006, is an American oil and gas services company headquartered in Houston, Texas. The company is a global provider of offshore services in well intervention and ROV operations of new and existing oil and gas fields.
Cameron International Corporation (formerly Cooper Cameron Corporation (CCC) and Cooper Oil Tool, Cameron Iron Works) though now operating under Schlumberger, is a global provider of pressure control, production, processing, and flow control systems as well as project management and aftermarket services for the oil and gas and process industries. Cameron was acquired by Schlumberger (SLB) in 2016, and now operates as 'Cameron, a Schlumberger Company.' At the start of the SLB acquisition in 2015, Cameron employed approximately 23,000 people and delivered $9.8 billion in revenue.
The Helix fast-response system (HFRS) is a deep-sea oil spill response plan licensed by HWCG LLC, a consortium of 16 independent oil companies, to respond to subsea well incidents. Helix Energy Solutions Group designed the Helix fast-response system based on techniques used to contain the 2010 Gulf of Mexico oil spill. On February 28, 2011 the drilling moratorium imposed as a result of the spill ended when the United States Department of the Interior approved the first drilling permit based on the availability of the HFRS to offshore oil companies.

The 2004 Taylor Energy oil spill is an ongoing spill located in the Gulf of Mexico, around 11 miles (18 km) off the coast of the U.S. state of Louisiana. It is the result of the destruction of a Taylor Energy oil platform during Hurricane Ivan in 2004. It is the longest-running oil spill in U.S. history. It was first brought to public attention when contamination at the site was noticed in 2010 by those monitoring the nearby Deepwater Horizon oil spill. A report by the Associated Press in 2015 challenged the estimates of the extent of the leak originally given by the company and the U.S. Coast Guard (USCG), which were then revised to be around 1,000 times greater than initially reported.
