Glossary

Here are some words about the natural gas industry that you might find interesting. We put them into sentences for you, but you can try to write some of your own.

#

800-4GAS
If there is an emergency, you can call NGC at 800-4GAS, or 800-4427.

a

Accident free
Having no accidents.
Air-conditioning
Machines used to keep buildings cool Natural gas can be used in air-conditioning systems.
Aluminium
A strong, light metal. Your mummy wraps your sandwiches in aluminium foil.
Ammonia
A chemical made from natural gas. Ammonia is used to fertilise plants. It is also used in cleaning liquids, like the one you use in the kitchen.
Arc-eye
Damage to the eye that can be caused by some very bright lights. This is why you must never look at welding operations.
Associated gas
Gas that is found in the same place as oil is called wet gas or associated gas.
Atoms
Very small particles of matter.

b

Butane
Butane is one of the gases in the natural gas stream. It is used in cigarette lighters.

c

Call first
Call first before you dig near an NGC pipeline marker!
Carbon dioxide
Carbon dioxide is one of the gases found in natural gas. The bubbles in your soft drink are made by carbon dioxide.
Caution tape
NGC buries caution tape above its pipelines to let you know to stop digging when you see it. The tape is yellow. The word CAUTION is printed on it in black.
Compression
Natural gas is pumped into the pipeline. This is called compression. This means that a of of gas is squeezed into a small space, to make it go faster through the pipelines.
Condensate
Small drops of liquid natural gas is called condensate. It is removed from the pipeline and sold.
Construction
Building or creating. Always be careful when pipelines are under construction near you.
Consumers
A consumer is a company that uses natural gas. NGC sells natural gas to over 100 consumers.
Cooling
Making temperatures lower, so you feel more comfortable. Some large buildings use natural gas in their air-conditioning or cooling systems.
Corrosion
Rusting. NGC takes care to avoid corrosion or rust, which can cause pipelines to crack or burst.
Cracking
Different gases are separated from the gas stream by a process called cracking.
Crude oil
Crude oil is the state in which oil is found before it is processed.
Cubic feet
Natural gas is measured in cubic feet. This is a unit of volume. A cubic foot of natural gas fits in a space that’s one foot wide by one foot long by one foot deep. This is about the size of a football.

d

Development
Growing or advancing. NGC contributes to the development of Trinidad and Tobago by supplying gas for electricity generation and to many factories and other consumers.
Digging
Digging near a natural gas pipeline can be dangerous, because the pipeline might get damaged. If you see anyone digging near a pipeline Right of Way, without NGC personnel present, call NGC on 800-4GAS.
Distribution
Small pipelines that leave the larger transmission pipelines and go to consumers are called distribution lines.
Drilling
To use a machine to dig deep into soil and rock. In Trinidad and Tobago, drilling is done for both oil and gas.

e

Economical
Bringing good value compared to the amount of money you spend. Natural gas is the most economical fossil fuel. This means you can get more heat from burning natural gas than you can from other fossil fuels like oil or coal.
Efficient
Getting the best result with the least effort or waste. Natural gas is a cheap and efficient fuel. It burns cleanly and leaves very little waste behind.
Emergency number
This is the number you call when you need help. Write down NGC’s emergency number (800-4427) and keep it nearby.
Encroachment
Taking up someone else’s space. Planting crops or building houses on NGC’s Right of Way (the area where the pipes are run), is called encroachment, and it’s both unsafe and illegal.
Energy
The strength needed to do things. All living things and machines need energy in order to function. We also need energy to make machines work.
Environmentally responsible
Causing the least harm to the environment. Natural gas is an environmentally responsible form of energy. It doesn’t leave much waste behind, and doesn’t create as much greenhouse gases as other fuels do.
Ethane
Ethane is one of the gases found in the natural gas stream. It is used to make ethylene, a raw ingredient in making plastic.
Ethylene
A raw ingredient in making plastic.
Evacuate
To leave a dangerous area quickly. If there is a serious gas leak in your area, you will be asked to evacuate.
Expand
To make larger. NGC is always expanding its pipeline network.
Exploration
To find out new things about an area. Exploration often leads to the discovery of more natural gas.
Export
To ship goods overseas.

f

Feedstock
A raw ingredient. Natural gas is a feedstock in making ammonia, urea and methanol.
Fertiliser
Ammonia and urea are both fertilisers, and are made from natural gas. Fertilisers make plants grow.
Field worker
People who work out in the open air. NGC field workers wear orange coveralls with the NGC logo.
Fields
Areas where oil or gas are found in abundance are called fields.
Flammable
Can catch fire easily. Natural gas is flammable.
Follow the rules
To do as you are told. If you follow the rules of natural gas safety, you and your community will be safe.
Fossil fuel
Fossil fuels, like natural gas, oil and coal, were formed millions of years ago by the remains of dead plants and animals.
Fuel
Fuels contain energy to make things go.

g

Gas field
An area where natural gas is found underground. Many gas fields in Trinidad are named after trees, flowers and animals.
Gas resources
The gas that is in the ground, waiting to be removed. NGC helps ensure that the natural gas resources of T&T are best used to the benefit of all citizens.
Gasolene
Natural gasolene is a liquid fuel found in the gas stream. It is removed and sold to refineries like Petrotrin.
Generate electricity
To create electricity using machines. Natural gas is used to generate electricity.
Greenhouse gas
Greenhouse gases are released when many fossil fuels are burned They can harm the ozone layer. Natural gas releases less greenhouse gases than the other fossil fuels like oil or coal, and thus does much less harm to the environment.

h

Heating
In cold countries, natural gas is used for heating buildings.
Hotline
A hotline is an emergency telephone number. NGC’s hotline 800-4GAS (800-4427) is operated 24 hours a day.
Hydrocarbon
Natural gas and oil are called hydrocarbons because they are made up of hydrogen and carbon atoms.

i

A common metal that is used in making many goods. Natural gas is used to heat the furnaces when making iron and steel.
Iron ore
Iron ore is a raw ingredient in making iron.

l

Landslides
Slipping of the land due to heavy rains or earthquakes. Landslides can cause pipeline ruptures.
Leak
An accidental hole that allows liquid or gas to escape. If you see bubbles in puddles of water where a gas pipeline is buried, that may mean there is a leak.
Liquefied Natural Gas
Natural gas that is converted to a liquid by freezing and storing in pressurised containers. It is also called LNG.
