Oil-producing countries include Venezuela, Canada, Saudi Arabia, Iran and Kuwait. Many countries in the world have abundant oil reserves. Kuwait is located in the northeast of Arabian Peninsula, bordering the Persian Gulf in the east, and the country is rich in oil resources.

Oil exploitation is the main economic lifeline of Kuwait, and more than 90% of its fiscal revenue comes from oil. Kuwait is sometimes called a country floating on a lake of oil. Petroleum is one of the main targets of geological exploration, and it is a viscous dark brown liquid called "industrial blood". There are oil reserves in some parts of the upper crust. The main components are mixtures of alkanes, cycloalkanes and aromatic hydrocarbons.

There are two theories about the mechanism of petroleum formation: biological deposition and petrochemical formation. The former is widely accepted that oil is formed by the long evolution of organisms in ancient oceans or lakes, which belongs to biological deposition and cannot be regenerated. The latter thinks that oil is generated by carbon in the earth's crust, which has nothing to do with living things and is renewable.

Petroleum is mainly used as fuel oil and gasoline, and it is also the raw material of many chemical industrial products, such as solutions, fertilizers, pesticides and plastics.
