Steerable motors are used to drill the kick-off point. When drilling the kick-off point be sure to avoid drilling a soft formation immediately below a hard one. In hard abrasive formations the high-side forces at kick off can cause severe bit shank wear. Ideally the kick-off point should be selected in a non-abrasive homogenous formation. [2]
If the drilling well penetrates the production string of a previously completed well, the formation fluid from the completed well will enter the wellbore of the drilling well, causing a kick. If this occurs at a shallow depth, it is an extremely dangerous situation and could easily result in an uncontrolled blowout with little to no warning of ...

Controlled losses allow drilling to continue while keeping the wellbore full, preventing an influx of gas or fluid into the wellbore, known as a "kick", which can lead to a blowout. [ 4 ] A number of options are available when lost circulation occurs, depending on the severity. [ 4 ]
The methods used to direct the well path fall into two broad categories, these being “push-the-bit” or “point-the-bit”. Push-the-bit tools use pads on the outside of the tool which press against the well bore thereby causing the bit to press on the opposite side causing a direction change.
President Joe Biden is commuting the sentences of nearly 1,500 people and pardoning 39 others in "the largest single-day act of clemency in modern history," the White House announced Thursday ...
high drilling rates; lowered drill pipe torque and drag, less bit balling and; reduction in differential sticking. Oil-based muds are expensive, but are worth the cost when drilling through: troublesome shales that would otherwise swell and disperse in water based mud e.g. smectite, to drill deep, high-temperature holes that dehydrate water ...
