Question Air
WHAT IS RIG? =>A drilling rig is a machine that creates holes in the earth sub-surface.
Drilling rigs can be massive structures housing equipment used to drill water
wells, oil wells, or natural gas extraction wells, or they can be small enough to be
moved manually by one person and such are called augers
Difference between onshore and offshore?
Onshore drilling refers to drilling deep holes under the earth's surface whereas
Offshore drilling relates to drilling underneath the seabed. These drilling methods
are used in order to extract natural resources – usually oil and gas – from the earth

WHAT IS RIG? =>A drilling rig is a machine that creates holes in the earth
sub-surface. Drilling rigs can be massive structures housing equipment used to drill
water wells, oil wells, or natural gas extraction wells, or they can be small enough to be
moved manually by one person and such are called augers
Mud tank
A mud tank is an open-top container,
typically made of square steel tube and steel plate, to store drilling fluid on a drilling rig. They
are also called mud pits, as they were once simple pits in the earth.
Shale shakers
Shale shakers are components of drilling equipment
used in many industries, such as coal cleaning, mining, oil and gas drilling
Mud Pump
A mud pump, is a reciprocating piston/plunger pump designed to circulate drilling fluid under
high pressure down the drill string and back up the annulus. A mud pump is an important part of
the equipment used for oil well drilling.
winch
A winch is a mechanical
device that is used to pull in (wind up) or let out (wind out) or otherwise adjust the "tension" of a
rope or wire rope (also called "cable" or "wire cable"). In its simplest form, it consists of a spool
and attached hand crank.
Standpipe
A rig standpipe is a solid metal pipe attached to the
side of a drilling rig's derrick that is a part of its drilling mud system. It is used to
conduct drilling fluid from the mud pumps to the kelly hose. Bull plugs, pressure transducers
and valves are found on the rig standpipe.
Treveling Block
A traveling block is the freely moving
section of a block and tackle that contains a set of pulleys ... of thousands of pounds. On
larger drilling rigs, when raising and lowering the derrick, line tensions over a million pounds
are not unusual.
Drill line
In a drilling rig, the drill line is a multi-thread, twisted wire
rope that is threaded or reeved through the traveling block and crown block to facilitate the
lowering and lifting of the drill string into and out of the wellbore. On larger diameter lines,
traveling block loads of over a million pounds are possible.
Crown Block
A crown block is the stationary section of a block and tackle that contains a set of pulleys or
sheaves through which the drill line (wire rope) is threaded or reeved and is opposite and above
the traveling block.
Derrick
A derrick is a lifting device composed at minimum of one guyed mast, as in a gin pole, which
may be articulated over a load by adjusting its guys. Most derricks have at least two
components, either a guyed mast or self-supporting tower, and a boom hinged at its base to
provide articulation, as in a stiffleg derrick.
Monkey Board
Swivel
A Swivel is a mechanical device used on
a drilling rig that hangs directly under the traveling block and directly above the kelly drive, that
provides the ability for the kelly (and subsequently the drill string) to rotate while allowing the
traveling block to remain in a stationary rotational position (yet allow
Kelly Drive
Rotary Table
A rotary table is a mechanical device on
a drilling rig that provides clockwise (as viewed from above) rotational force to the drill string to
facilitate the process ofdrilling a borehole
Bell Nipple
The bell nipple is usually fitted
with a side outlet to permit drilling fluids to flow back to the surface mud treating
equipment through another inclined pipe called a flowline.
Blowout preventer
A blowout preventer (BOP) is a large, specialized
valve or similar mechanical device, used to seal, control and monitor oil and gas wells to
prevent blowouts, the uncontrolled release of crude oil and/or natural gas from a well. They are
usually installed in stacks of other valves
BOP Annular
An annular blowout preventer uses the principle of a
wedge to shut in the wellbore. It has a donut-like rubber seal, known as an elastomeric packing
unit, reinforced with steel ribs. The packing unit is situated in the BOP housing between the
head and hydraulic piston.
Casing Heads
In oil drilling, a casing head is a simple metal flange
welded or screwed onto the top of the conductor pipe (also known as drive-pipe) or
the casing and forms part of the wellhead system for the well
Flow Line
A flow line, used on a drilling rig, is a large diameter pipe
(typically a section of casing) that is connected to the bell nipple (under the drill floor) and
extends to the possum belly (on the mud tanks) and acts as a return line, (for the drilling fluid as
it comes out of the hole), to the mud tanks
