Natural Gas

Definition - What does Natural Gas mean?

Natural Gas is a fossil fuel which is used as a source of energy. It is considered as a hydrocarbon and once burnt it is lighter than air. It is the safest, cleanest and environment friendly source of energy. Natural gas which is produced along with crude oil is known as associated gas while natural gas which is produced alone is known as dry gas.

Petropedia explains Natural Gas

Natural gas can either be found in association with oil or existing by itself. When it is found in association with oil, it will come out along with the oil production. It can also be found to exist alone meaning that only natural gas is available and there is no oil or condensates.

As it is a fossil fuel, just like crude oil, it is also produced from remains of plants and animals that existed millions of years ago. These organisms were buried and exposed to heat as a result of being highly compressed underneath thousands of meters of soil and rock. These forces transform the once living organisms into natural gas.

Natural gas is generally 90% to 95% methane and the other percentage is composed of ethane, propane and butane. When natural gas is traded between two or more entities, it is measured in BTU’s (British thermal unit).
