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.

Corrections are regularly made by techniques as simple as adjusting rotation speed or the drill string weight (weight on bottom) and stiffness, as well as more complicated and time ...
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 ...
