the drilling and operating companies well control policies. For workover or completion operations, other methods are often used. Bullheading is a common way to kill a well during workovers and completions operations but is not often used while drilling. Reverse circulation is another kill method used for workovers that are not used for drilling ...
As technology has advanced, more modern drillers have better control of the overall well. Oil well control is the management of the dangerous effects caused by the unexpected release of formation fluid, such as natural gas and/or crude oil, upon surface equipment of oil or gas drilling rigs and escaping into the atmosphere.
The tubing may also have flow control mechanism. Single-well concentric kill string: within the well a small diameter concentric kill string is used to circulate kill fluids when needed. Single-well 2-tubing completion: in this instance 2 tubing strings are inserted down 1 well. They are connected at the lower end by a circulating head.

Well intervention vessel Skandi Constructor. A well intervention, or well work, is any operation carried out on an oil or gas well during, or at the end of, its productive life that alters the state of the well or well geometry, provides well diagnostics, or manages the production of the well.
Founded in 1975, Wild Well is the world's leading provider of onshore and offshore well control emergency response, pressure control, relief well planning, engineering, and training services. Wild Well Control was founded by Joe R. Bowden Sr. in 1975 (July 15, 1932 – November 12, 2006). [ 3 ]
Another reason relates to the hydraulic control line. Hydraulic pressure is required to keep the valve open as part of the failsafe design. However, if the valve is too far down the well, then the weight of the hydraulic fluid alone may apply sufficient pressure to keep the valve open, even with the loss of surface pressurisation.
