Natural gas is a naturally occurring mixture of gaseous hydrocarbons and consists mainly of methane. Other constituents include ethane, propane, butane and heavier hydrocarbons. The composition of the gas differs from one gas reservoir to another.

Natural gas reserves can be found around the world. These exist as gas or in solution with oil in natural underground reservoirs. Such reservoirs occur in places off Trinidad’s north, south and east coasts.

Until well into the 20th century, natural gas was considered a nuisance and a by-product of crude oil extraction. In most cases, the natural gas was flared. Subsequent discoveries of large discoveries of large quantities of gas led to the development of local industries to use it for the production of ammonia, methanol and as an energy source.
