Eventually, crude oil will run out. Other sources will need to be discovered to replace crude oil and the many products produced.
Petrol is made out of crude oil which is a natural resource. When the crude oil is refined, petrol is produced in addition to other by-products like diesel.
Crude oil is the raw form of oil mined from underground, not produced. Some places with alot of crude oil however are Alaska and Canada.
Crude oil is a mixture of compounds called hydrocarbons. Many useful materials can be produced from crude oil. It can be separated into different fractions using fractional distillation, and some of these can be used as fuels. Unfortunately, there are environmental consequences when fossil fuels such as crude oil and its products are used.
It varies alot. The minimum value is zero- as some crude oil are refined into other products. So, let's assume this is a crude that is economical to refine into gasoline. In this case , it can be as low as 2 gallons or as high as 23 gallons. (1 bbl = 42 gallons) Expressed as a percentage of the crude oil, this is 5 to 55%. (See attached links). The crude oil not refined as gasoline will be refined for other products. Common refined products from crude oil are provided in the related link, and will differ depending on the properties of the crude oil. It's very interesting that after refining, there will be more gallons of produced products than the original barrel of crude oil.
Natural gas and water may be produced along with the crude oil. For this reason, when the crude oil is produced, it must be processed and the gas and water separated out, so the oil can be sold to refineries.
if you mean CRUDE OIL by term 'oil' then products like petrol,gasoline,asphalt,kerosene,waxes etc. are obtained by fractional distillation or refining of crude oil. In the process of oil refining ,first step is neutralization or removiving of free fatty acids, during this first step soap is produced.
Natural gas is less expensive to produce than distilling crude oil for heating. Though, many different products are produced by distilling and refining crude oil, especially in plastics, etc.
gas, crude oil metals,precious stones, machenery and equipment.
Because Australian crude is not suitable for some of the products that come from crude oil.
"Petroleum" products are distilled from crude oil, so what comes out of the ground is crude oil.
