What is natural gas?


Natural gas is a hydrocarbon that is composed of mostly methane, but also contains other compounds such as ethane, propane, butane, and pentanes, collectively called natural gas liquids (NGLs). These are different from liquefied natural gas (LNG), which is natural gas that’s been super-cooled until it becomes a liquid. Natural gas may also contain sulphur compounds, nitrogen, carbon dioxide, water and other substances. Canada’s natural gas comes from British Columbia, Alberta and Saskatchewan.
