Raw natural gas as it comes from the wellhead is mostly comprised of methane (the largest constituent of household natural gas), but also contains various heavier hydrocarbons. The heavier hydrocarbons consist of ethane, propane, butanes, pentanes plus, and condensate; and are called natural gas liquids (NGLs). In Canada, most NGLs are produced at natural gas processing plants, with the remainder produced as a byproduct of oil refining or bitumen upgrading.
The Canada Energy Regulator regulates the export of ethane, propane and butanes. Export orders or licences are required to export these NGLs from Canada. Holders of export authorizations report monthly on their export activities to the Commission.
This dataset provides historical export volumes of NGLs (by year and month), by origin, destination, and mode of transportation of the exports.
