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]
KBUG – kelly bushing underground (drilling up in coal mines, West Virginia, Baker & Taylor drilling) KCI – potassium chloride; KD – kelly down; KMW – kill mud weight; KOEBD – gas converted to oil-equivalent at 6 million cubic feet = 1 thousand barrels; KOH – potassium hydroxide; KOP – kick-off point (directional drilling) KOP ...
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 ...
Kelly: A square or hexagon pipe ( Approximately 40 ft. long ) used to turn the drill string while drilling. Kick: An intrusion of pressurized fluid into the wellbore that causes drilling fluid to be displaced. It can be the precursor to a blowout. Kickoff: A planned deviation from vertical, executed at the bottom of the wellbore.
It is based on pore pressure, kick tolerance, casing functions, casing design and cementing. It is sometimes related to drilling and petroleum engineering . [ 1 ]
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 principle of mud/gas separation for different types of vessels is the same. [3]Closed bottom type; Open bottom type; Float type; The closed-bottom separator, as the name implies, is closed at the vessel bottom with the mud return line directed back to the mud tanks.
Drill cuttings can be separated from liquid drilling fluid by shale shakers, by centrifuges, or by cyclone separators, the latter also being effective for air drilling. In cable-tool drilling, the drill cuttings are periodically bailed out of the bottom of the hole. In auger drilling, cuttings are carried to the surface on the auger flights.
