Petroleum is the main source of energy for transportation. Petroleum fuels are made from crude oil and liquids from natural gas processing. The petroleum fuels used for transportation include gasoline, diesel fuel, jet fuel, residual fuel oil, and liquid petroleum gases.
Crude oil and natural gas occur in ‘pockets’ under the ground. Sometimes the deposits are found under the sea bed. Like other deposits, they are extracted by drilling a hole down through the rocks into the oil or gas. For undersea deposits, the drills are mounted on a platform called a drilling rig. The oil or gas is usually pumped ashore through pipelines.
