Natural gas is a mixture of light hydrocarbons, which for the most part is composed of methane and to a lesser extent of ethane, propane, butane, pentane and heavier hydrocarbons.
Natural gas is found in underground wells, just like oil. It may or may not be associated with oil.
It is formed when layers of decomposing plant and animal matter are exposed to intense heat and pressure below the Earth’s surface for several years.
Natural gas is mainly distributed through steel and polyethylene pipelines, materials of high resistance and durability. In liquid state, natural gas can also be distributed through cryogenic containers.
