Appraisal well

a well drilled as part of an appraisal

drilling program

Appraisal drilling

drilling carried out to determine the physical

extent, reserves and likely production

rate of a field

Purging

cleansing of processing equipment, or

pipelines Vessels must be purged of

noxious gases by sweeping them with air

before removing manways or entering

them for cleaning or inspection Pipelines

must be purged of material, e g water,

before they are placed into service to

carry crude oil or natural gas

Paleozoic era

the era of geological time (comprising the

Cambrian, Ordovician, Silurian,

Devonian, Carboniferous and Permian

Periods) which began roughly 600 million

years ago and ended roughly 230 million

years ago

Vapor

substance in a gaseous state

Paraxylene

an aromatic compound used in the manufacture

of polyester fibers

Wax

solid hydrocarbon which is present in some

crude oils, especially in paraffinic crudes

Wax deposits in pipelines and equipment

can cause mechanical problems

Paraffin

a name given in the UK to the premium

grade of kerosene burned in lamps and

flueless space heaters, a member of the

paraffin (alkane) series of hydrocarbons

Paraffins

the alkanes

Conventurer

a person or company joined with others

in a particular venture, see consortium

Foam

a mass of stabilized bubbles in a liquid,

e g crude oil, believed to be caused by

high surface tension or the presence of

finely divided solid particles Foam can

be a nuisance in processing and may be

suppressed by chemical means using

anti-foam agents

Pentane

the saturated hydrocarbon (alkane) with

five carbon atoms in its molecule (C5H12)

the fifth member of the paraffin series - a

liquid under normal conditions

with the (fixed) crown block for

raising and lowering the drill string,

casing, etc

Agitators

mixing devices used to bring about intimate

contact between liquids or solutions

of dissolved solids or to keep solids suspended

in liquids

Pressure drop

the decrease in pressure due to energy

losses, such as friction which occurs

when a liquid or gas passes through a

pipe, vessel or other piece of equipment

By-pass

a pipe connected around a valve or

other control mechanism in a flow line in

order to maintain flow during adjustments

or repair
