The DNV final report indicated that the second tube was the segment of the drill string that was ejected after being cut by the blow out preventer shears. On July 10, 2010, BP began operations to install a sealing cap, also known as a capping stack, atop the failed blowout preventer stack.
Death Stacks is an abstract strategy board game for two players invented by Stephen Euin Cobb. Death Stacks can be classified as a variant of the game Focus by Sid Sackson, published in A Gamut of Games. The Annual Death Stacks Tournament is held in Charlotte, North Carolina each summer and is hosted by the science fiction convention, ConCarolinas.
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. [1] 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.
Much of the offshore seabed diving work is inspection, maintenance and repair of the blow-out preventers (BOPs) and their permanent guide bases. The primary functions of a blow-out preventer system are to confine well fluid to the wellbore, provide a way to add fluid to the wellbore and to allow controlled volumes of fluid to be withdrawn from the wellbore.
Deepwater Horizon drilling rig blowout, 21 April 2010. Kick is defined as an undesirable influx of formation fluid into the wellbore. If left unchecked, a kick can develop into a blowout (an uncontrolled influx of formation fluid into the wellbore). The result of failing to control a kick leads to lost operation time, loss of well and quite ...
The BOP stack is connected -- usually with bolted flanges -- to the casing head, which itself is welded or screwed onto the casing that has been cemented in place. (No BOP's are used in drilling the very top portion of the hole.) In subsea operations, the BOP stack's bottom connector is controlled hydraulically upon command from the surface.
The Cameron ram-type blowout preventer was the first successful blowout preventer (BOP) for oil wells. It was developed by James S. Abercrombie and Harry S. Cameron in 1922. [1] [2] The device was issued U.S. patent 1,569,247 on January 12, 1926. [3] The blowout preventer was designated as a Mechanical Engineering Landmark in 2003. [1] [2] [4]
In oil well control, a kick should be able to be detected promptly, and if a kick is detected, proper kick prevention operations must be taken immediately to avoid a blowout. There are various tell-tale signs that signal an alert crew that a kick is about to start. Knowing these signs will keep a kicking oil well under control, and avoid a blowout:
