Definition
Access and Egress
Entry and exit.
Air Drilling
A method of rotary drilling that uses compressed air as its circulation medium to
remove cuttings from the borehole.
Air Knife
A device that directs compressed air to advance a hole. Usually used in
conjunction with a vacuum truck. Generally used to safely advance a borehole
through depths where underground utilities are generally present but may have
not been otherwise identified.
Angle Drilling
Drilling that is deliberately made to depart significantly from the vertical. Usually
performed with standard drilling rig with the mast deliberately set non-vertical.
Allows for installation of wells adjacent to, or just beneath surface structures.
Annular Space
The space between two well casings or between the casing and the wall of the
drilled hole.
Auger Fork
A U-shaped tool that is inserted around the auger flights to hold them in place on
the surface of a borehole.
Auger Head
The part of the auger that is attached to the drilling drive (gimbal and kelly).
Auger/Auger Flight
Any of various tools or devices having a helical shaft or member that are used for
boring holes.
Bit
The cutting or boring element used in drilling wells.
Boom Truck
A vehicle with a crane arm used for lifting augers, casing, or other heavy
equipment.
Borehole
The hole drilled by the bit. A borehole may have casing in it or may be open
(uncased), or a portion of it may be cased and a portion of it may be open.
Casing
A tubular retaining structure which is installed in the well bore to maintain the
well opening.
Casing Advancer
Drilling
A drill method that pushes casing forward as the drill bit is advanced (air
hammer)
Cathead
A spool-shaped attachment on the end of the cat shaft, around which rope for
hoisting and moving heavy equipment on or near the rig floor is wound.
Chemical
Any element, chemical compound, or mixture of elements or compounds.
