Petroleum is an oil used to power many things such as cars. Crude (unrefined) oil must be refined in order to be useful. Although the assignment is to find "the"volume of the world's petroleum reserves, there is no exact number because new reserves are constantly being discovered.

The United States Geological Survey's (USGS) World Energy Resources Program (WERP) produces the federal government's estimates of world oil resources. The volume of the world's petroleum reserves is important because of the fear that the oil will run out. This fear should be expected, because the estimated 1 trillion barrels of crude oil is only enough to supply the world for about 50 years. This prediction is based on the present world consumption, however, world consumption is expected to increase. Although the known reserves are only about a trillion barrels (1 barrel equals 159 liters, 42 gallons, or 0.16 m3), the estimated world reserves, according are about 1.5 × 1011 m3.

The Middle East has about 50% of the world's oil reserves, whereas the United States only has about 2%. The Organization of Petroleum Exporting Countries (OPEC) includes the following countries: Algeria, Nigeria, Indonesia, Iran, Iraq, Kuwait, Qatar, Saudi Arabia, and Venezuela. This organization decides on the production of oil for its members, which decide the price of oil for the countries who buy oil from this organization.
