natural gas which contains large amounts
of associated liquids.
Aqueous
watery, usually applied to solutions indicating
water is present
Deadweight Ions
total carrying capacity of a ship in tons
when loaded to the appropriate freeboard
during the summer season
Diver
anyone who works underwater in a wet
suit, diving bell or hyperbaric chamber
Saturation diving
a technique whereby divers work and live
under high pressure for long periods
instead of undergoing decompression
after every job
Diving bell
a pressure chamber from which divers
work underwater, the water being kept
out by means of high internal air pressure,
can also be used as an
observation chamber
Water drive
a recovery process in which oil or gas is
driven out of a reservoir by the pressure
of underlying water
РН
a measure of the acidity or alkalinity of a
solution which is a function of the hydrogen-
ion concentration The рН scale is a
logarithmic scale and ranges from 0,
which represents a strong acid, to 14,
which, represents a strong alkali A
neutral solution, which is neither acidic
nor alkali, and pure water, have a рН
value of 7
Reciprocal
acting with a backward and forward
movement, as in reciprocating pumps
Air
the gaseous environment surrounding the
Earth The approximate composition of
dry air by volume at sea level is nitrogen,
78 percent, oxygen, 21 percent, argon, 9
percent, carbon dioxide, ОЗ percent, and
other rare gases, 0 0024 percent
Possible reserves
undeveloped oil and/or gas reserves
which best engineering judgement indicates
might eventually be recoverable
from undrilled or untested structures
Drill collars
lengths of extra-heavy steel tubing located
immediately above the drill bit in order
to maintain pressure on the bit and keep
the drill string in tension
Rotary drilling
drilling in which the entire drill string
and bit are rotated, as opposed to
turbine drilling
Booster station
a platform built part of the way along an
oil or gas underwater pipeline in order to
boost the pumping process
Going in hole
lowering the drill string into the well bore
Kick
the situation that occurs when the formation
pressure in a well exceeds the
hydrostatic head of the mud column,
thus allowing formation fluid to enter the
well bore
Flare stack
the steel structure on a rig or platform
from which gas is flared, see flaring
Blow molding
a plastic-forming process that makes use
of compressed air to shape the final
product by expanding it to fit the mold
