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.
English: CYCLIC STEAM STIMULATION ("Huff-and-Puff') (A well-stimulation method) This method is sometimes applied to heavy-oil reservoirs to boost recovery during the primary production phase. During this time it assists natural reservoir energy by thinning the oil so it will more easily move through the formation to the injection/production wells.
The first snubbing unit was primarily designed to work in well control situations to "snub" drill pipe and or casing into, or out of, a well bore when conventional well killing methods could not be used. Unlike conventional drilling and completions operations, snubbing can be performed with the well still under pressure (not killed). When done ...

Deepwater wellbore integrity can be defined as the application of relevant engineering techniques and operational measures in deepwater drilling to control related risks during the drilling process, ensuring that deepwater oil and gas wells are always in a safe state throughout their entire life cycle.
