Natural gas is a mixture of light hydrocarbons found naturally within the Earth's crust. It is predominantly made up of methane mixed with other components such as ethane, propane, butane, pentane, carbon dioxide and nitrogen.
As a fossil fuel, it is derived from organic material deposited and buried in the Earth millions of years ago. Historically, natural gas also has been one of the most economical energy sources.
We can find natural gas around the world by exploring for it in the Earth's crust and then drilling wells to extract it.
Natural gas can be transported over long distances in pipelines or as liquefied natural gas (LNG) transported in ships across oceans. Natural gas can be stored until needed in underground caverns and reservoirs or as LNG in atmospheric tanks.
An environmentally friendly and efficient energy source, natural gas is the cleanest-burning conventional fuel.
Increasing Global Demand
Dismissed as a useless by-product of crude oil production until the second half of the 20th century, natural gas now accounts for about 22 percent of the world's energy consumption. And the demand is growing.
What Chevron Is Doing
To address the increasing demand for natural gas globally, we are leading two key developments in Australia, the Gorgon Project based on Barrow Island, off shore Western Australia and the Wheatstone Project on the West Pilbara coast of Australia.
We are also a long time participant in Australia's North West Shelf Venture, which operates offshore producing fields and extensive onshore facilities and a domestic gas plant.
Liquefied Natural Gas
Liquefied natural gas is natural gas that has been cooled to -162 degrees Celsius (-260°F), the point where it condenses to a liquid.
Liquefaction reduces the volume by approximately 600 times, making it more economical to transport between continents in specially designed ocean vessels.
Natural gas is processed into LNG by first removing carbon dioxide, water and heavy hydrocarbons, such as butanes, pentanes and hexanes, and other materials.
It is then processed and condensed to a liquid, ready for loading onto LNG ships for export.
After arriving at its destination, LNG is warmed to return it to its gaseous state and delivered to natural gas customers through local pipelines.
Throughout the process of converting natural gas to and from LNG, exemplary safety and security measures are employed.
