Accumulator
The storage device for nitrogen pressurized hydraulic fluid, which is used in operating the blowout preventers.
Conductor Pipe
The largest diameter casing and the topmost length of casing. It is relatively short and encases the topmost string of casing.
Crown Block and Water Table
An assembly of sheaves or pulleys mounted on beams at the top of the derrick. The drilling line is run over the sheaves down to the hoisting drum.
Doghouse
A small enclosure on the rig floor used as an office for the driller or as a storehouse for small objects. Also, any small building used as an office or for storage.
Drawworks
The hoisting mechanism on a drilling rig. It is essentially a large winch that spools off or takes in the drilling line and thus raises or lowers the drill stem and bit.
Drill Bit
The cutting or boring element used in drilling oil and gas wells. Most bits used in rotary drilling are roller-cone bits. The bit consists of the cutting elements and the circulating element. The circulating element permits the passage of drilling fluid and uses the hydraulic force of the fluid stream to improve drilling rates.
Drill Collar
A heavy, thick-walled tube, usually steel, used between the drill pipe and the bit in the drill stem. It is used to put weight on the bit so that the bit can drill.
Drill Pipe
The heavy seamless tubing used to rotate the bit and circulate the drilling fluid. Joints of pipe 30 feet long are coupled together with tool joints.
Driller's Console
The control panel, located on the platform, where the driller controls drilling operations.
Drilling Line
A wire rope hoisting line, reeved on sheaves of the crown block and traveling block (in effect a block and tackle). Its primary purpose is to hoist or lower drill pipe or casing from or into a well. Also, a wire rope used to support the drilling tools.
Electric Control House
On diesel electric rigs, powerful diesel engines drive large electric generators. The generators produce electricity that flows through cables to electric switches and control equipment enclosed in a control cabinet or panel. Electricity is fed to electric motors via the panel.
Electric Cable Tray
Supports the heavy electrical cables that feed the power from the control panel to the rig motors.
Elevators
A set of clamps that grips a stand, or column, of casing, tubing, drill pipe, or sucker rods, so the stand can be raised or lowered into the hole.
The storage device for nitrogen pressurized hydraulic fluid, which is used in operating the blowout preventers.
Annular Blowout Preventer
A large valve, usually installed above the ram preventers, that forms a seal in the annular space between the pipe and well bore. If no pipe is present, it forms a seal on the well bore itself.
Blowout Preventer
A large valve, usually installed above the ram preventers, that forms a seal in the annular space between the pipe and well bore or, if no pipe is present, on the well bore itself.
Brake
The braking device on the drawworks to stop a load being
lifted.
Bulk Mud Components in Storage
Hopper type tanks for storage of drilling fluid components.
Casing Head
A heavy, flanged steel fitting connected to the first string of casing. It provides a housing for slips and packing assemblies, allows suspension of intermediate and production strings of casing, and supplies the means for the annulus to be sealed off. Also called a spool.
Cathead
A spool-shaped attachment on a winch around which rope for hoisting and pulling is wound.
Catline Boom and Hoist Line
A structural framework erected near the top of the derrick for lifting material.
Catwalk
The ramp at the side of the drilling rig where pipe is laid to be lifted to the derrick floor by the catline or by an air hoist.
Cellar
A pit in the ground to provide additional height between the rig floor and the well head to accommodate the installation of blowout-preventers, ratholes, mouseholes,and so forth. It also collects drainage water and other fluids for disposal.
Choke Manifold
The arrangement of piping and special valves, called chokes, through which drilling mud is circulated when the blowout preventers are closed to control the pressures encountered during a kick.
Annulus
The space around a pipe in a well bore, the outer wall of which may be the wall of either the bore hole or the casing; sometimes termed the annular space.

Degasser
The equipment used to remove unwanted gas from a liquid, especially from drilling fluid.

Desander
A centrifugal device for removing sand from drilling fluid to prevent abrasion of the pumps. It may be operated mechanically or by a fast-moving stream of fluid inside a special cone-shaped vessel, in which case it is sometimes called a hydrocyclone.
Desilter
A centrifugal device, similar to a desander, used to remove very fine particles, or silt, from drilling fluid. This keeps the amount of solids in the fluid to the lowest possible level.
