Drilling contractor

a company that undertakes to provide

the equipment and manpower needed to

drill a well on behalf of an operator

Drilling mud

a mixture of clays, water and chemicals

pumped down the drill string and up the

annulus during drilling in order to lubricate

the system, carry away rock cuttings,

maintain the required pressure at

the evaluation, etc

Drilling table

the table on the derrick floor whereby

the drill pipe is rotated, also called the

rotary table

Rotary hose

the flexible hose that transfers the drilling

mud from the stand pipe to the top of the

drill string via a swivel coupling

Mud pumps

pumps used to circulate drilling mud at

the desired pressure and flow rate, also

called slush pumps

Butadiene

an unsaturated derivative of butane, one

of the most important raw materials used

in the manufacture of synthetic rubber

Butane

the saturated hydrocarbon (alkane) with

four carbon atoms in its molecule

(C4H10), the fourth member of the paraffin

series, a gas at atmospheric pressure

and normal temperature, but easily liquefied

by pressure for transportation and

subsequent use

Doghouse

a small shelter located on the rig floor for

use by the drilling crew

Town gas

the traditional type of locally manufactured

gas fuel, originally made from coal

Vacuum

a system is under vacuum when its pressure

is below that of the surrounding

atmosphere The lower the pressure, the

higher the vacuum

Carried interest

when a company pays for all or part of a

partner's costs during exploration or

development, e g when a company

"carries" a state that retains a participation

interest in a field

Updip

the opposite of downdip

Kelly

a square or hexagonal hollow shaft which

engages at one end with the drilling table

and at the other with the drill pipe

Probable reserves

undeveloped oil and/or gas reserves

considered to be recoverable from penetrated

formations but lacking information

to be classified as proven reserves

Heave

the up-and-down movement of a

semisubmersible drilling platform or drill ship

Swivel

the rotating coupling which connects the

rotary hose to the drill string

Heliport

a land base from which helicopters

operate

Helipad

the platform on an offshore installation on

which helicopters land

Derrick man

the member of the drilling crew who

works up the derrick, also known as the

derrick monkey

Explosion

a violent, uncontrolled release of pressure

causing noise and possibly accompanied

by fire and evolution of gases

Sampling

the process of obtaining a small quantity

of material which is as representative as

possible of the total volume

Shale shaker

a vibrating or rotating screen which

removes the coarse drill cuttings from the

drilling mud prior to its recirculation
