Fossil petroleum because we can see in terms of fossilization but scientists beberepa bersependapat that petroleum does not include fossil fuels, why do so because of the formation of oil at high temperature and pressure so that the fossil has not been formed since been destroyed by the extremely high temperatures and is therefore not absolute oil / absolute can be said of fossils. But many said oil as fossil fuels, derived from the rubble of the remains of plants and large networks hewan.Sebagian destroyed organic material into gas that is lost to the atmosphere, but at the time of the gas produced is very large, some stayed and stuck in a sediment . Marine Microorganisms were destroyed, and then form the oil and natural gas.
black liquid which is a mixture of different types of hydrogen-carbon molecule, so that when burned will produce carbon dioxide gas (CO2) and water (H2O).
Petroleum is found beneath the earth's surface at a depth of 500 - 2500 m. For that crude oil must be pumped out and then streamed to the installation of oil refineries to be processed to obtain various types of fuel oil for example, (gasoline, diesel, kerosene etc).
Besides being used as fuel, petroleum is also used as raw material for plastics and chemical industries.
As a source of energy, oil suitable for transport purposes, eg for vehicle fuel, because it has a high energy content per volume
