Offshore drilling

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 which 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.

Offshore drilling presents environmental challenges, both from the produced hydrocarbons and the materials used during the drilling operation. Controversies include the ongoing US offshore drilling debate.

There are many different types of facilities from which offshore drilling operations take place. These include bottom founded drilling rigs (jackup barges and swamp barges), combined drilling and production facilities either bottom founded or floating platforms, and deepwater mobile offshore drilling units (MODU) including semi-submersibles and drillships. These are capable of operating in water depths up to 3,000 metres (9,800 ft). In shallower waters the mobile units are anchored to the seabed, however in deeper water (more than 1,500 metres (4,900 ft) the semisubmersibles or drillships are maintained at the required drilling location using dynamic positioning.

A.P. Moller–Maersk Group (Danish: A.P. Møller–Mærsk A/S, Danish pronunciation: [ˈæːˀ ˈpʰeːˀ mølɐˈmæɐ̯sg̊]), also known as Maersk, is a Danish business conglomerate. A.P. Møller – Maersk Group has activities in a variety of business sectors, primarily within the transportation and energy sectors. It has been the largest container ship operator and supply vessel operator in the world since 1996.

A.P. Møller – Maersk Group is based in Copenhagen, Denmark, with subsidiaries and offices in more than 135 countries worldwide and around 89,000 employees. It ranked 148 on the Forbes Global 2000 list for 2015.

History

A.P. Møller – Maersk Group started as the shipping company Dampskibsselskabet Svendborg (Danish for "Svendborg Steamship Company") founded by captain Peter Mærsk-Møller and his son Arnold Peter Møller (2 October 1876 - June 1965) in Svendborg, April 1904. A.P. Møller had four children, two by each of his two wives Chastine Estelle Roberta Mc-Kinney and Norwegian-born Pernille Ulrikke Amalie Nielsen. A.P. Møller's second child was Arnold Mærsk McKinney Møller (13 July 1913 – 16 April 2012).

Petroleum engineering

Petroleum engineering is a field of engineering concerned with the activities related to the production of hydrocarbons, which can be either crude oil or natural gas. Exploration and Production are deemed to fall within the upstream sector of the oil and gas industry. Exploration, by earth scientists, and petroleum engineering are the oil and gas industry's two main subsurface disciplines, which focus on maximizing economic recovery of hydrocarbons from subsurface reservoirs. Petroleum geology and geophysics focus on provision of a static description of the hydrocarbon reservoir rock, while petroleum engineering focuses on estimation of the recoverable volume of this resource using a detailed understanding of the physical behavior of oil, water and gas within porous rock at very high pressure.

The combined efforts of geologists and petroleum engineers throughout the life of a hydrocarbon accumulation determine the way in which a reservoir is developed and depleted, and usually they have the highest impact on field economics. Petroleum engineering requires a good knowledge of many other related disciplines, such as geophysics, petroleum geology, formation evaluation (well logging), drilling, economics, reservoir simulation, reservoir engineering, well engineering, artificial lift systems, completions and oil and gas facilities engineering.
