Hyperbaric chamber

a chamber whose interior can be maintained

at a high pressure in order to allow

saturation divers to live under the same

pressure conditions at which they work

underwater, a chamber in which such

divers work or are transported underwater

Bends

a serious (or even fatal) condition suffered

by divers who are decompressed

too quickly - caused by nitrogen bubbles

forming in the blood

Kimeridgian

a formation in the upper strata of the

Jurassic Period that contains both source

and reservoir rocks

Cimmerian unconformity

a period of emergence and subsequent

erosion that occurred at the end

of the Jurassic Period and was followed

by further deposition of sediments,

see unconformity

Acid

a substance which forms hydrogen ions

in solution which may be replaced by a

metal to form salts Acids are usually

sour, corrosive and turn blue litmus red

Acidizing

a stimulation technique whereby acid is

injected into the reservoir rock, thereby

enlarging the pore spaces and increasing

the flow of oil

Acidic

having the properties of an acid

Opposite to alkaline

Valves

devices to control or regulate the flow of

liquids or gases through pipes The main

types are diaphragm, gate, globe, butterfly,

check, ball, plus and relief

Tong line

a wire, mamlla or fiber горе, attached to

a long handle in order to exert torsion on

a pipe

Slips

steel wedges which are forced into the

tapered opening of the drilling table to hold

the free end of the drill pipe in place

Pipe tongs

see tongs

Coke

hard carbon and other crude oil impurities

which can form inside furqace

tubes, etc

Bubble cap

a covered hole in a tray of a fractionating

column via which vapor bubbles

upwards through the liquid in the tray

Stabilizer tower

a fractionating column used to lower the

vapor pressure of gasoline products

during the refining process

Compensators

hydraulically operated equipment that

compensates for the upward and downward

motion (heave) of a floating rig or

drill ship during drilling operations

Compressor

equipment used to compress gas, for

re-injection into a well or for pumping

through a pipeline

Convection

transference of heat through a liquid or

gas by the actual movement of the fluid

Conversion oil

feedstock used in the manufacture of

carbon black

Conversion

the process whereby appliances, furnaces,

or boilers are modified so that

they can burn a different fuel than that for

which they were originally designed

Condenser

equipment for changing a material from

its vapor state to its liquid state

Condensates

see liquefied petroleum gas

Steam trap

a device which permits the discharge of

water arising from condensed steam from

pipelines, heat exchangers, etc, without

a loss of steam
