Offshore drilling rigs have similar elements, but are configured with a number of different drilling systems to suit drilling in the marine environment. The equipment associated with a rig is to some extent dependent on the type of rig but typically includes at least some of the items listed below.
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.
These rigs use the same technology and equipment as the oil drilling rigs, just on a smaller scale. The drilling mechanisms outlined below differ mechanically in terms of the machinery used, but also in terms of the method by which drill cuttings are removed from the cutting face of the drill and returned to surface.
Operated by Shell, with JV partners Chevron (37.5%) and BP (27.5%), the spar acts as a hub for and enables development of three fields Great White, Tobago, and Silvertip. The oil and gas fields beneath the platform lie in a geological formation holding resources estimated at 3–15 billion barrels of oil equivalent according to a report by the BSEE, formerly known as the MMS.
An oil rig is any kind of apparatus constructed for oil drilling. Kinds of oil rig include: Drilling rig, an apparatus for on-land oil drilling; Drillship, a floating apparatus for offshore oil drilling; Oil platform, an apparatus for offshore oil drilling; Oil well, a boring from which oil is extracted
Offshore drilling rig, c. 1968. The first semi-submersible resulted from an unexpected observation in 1961. [12] Blue Water Drilling Company owned and operated the four-column submersible Blue Water Rig No.1 in the Gulf of Mexico for Shell Oil Company. As the pontoons were not sufficiently buoyant to support the weight of the rig and its ...
At the same time, the number of U.S. drilling rigs has plunged to 586 from more than 1,900 in 2014. While the rate of growth is expected to slow, more oil will keep gushing out.
This is a list of the tallest oil platforms over 300 m (984 ft) in height. The current highest oil platform is the Petronius platform operated by Chevron Corporation and Marathon Oil in the Gulf of Mexico , 210 km southeast of New Orleans, United States.
