List of countries by proven oil reserves - Wikipedia

Methodology[edit] Proven reserves are those quantities of petroleum which, by analysis of geological and engineering data, can be estimated, with a high degree of confidence, to be commercially recoverable from a given date forward from known reservoirs and under current economic conditions. Some statistics on this page are disputed and controversial. Because proven reserves include oil recoverable under current economic conditions, nations may see large increases in proven reserves when known, but previously uneconomic deposits become economic to develop.

Oil by country

All oil producing countries. This article includes a chart representing proven reserves, production, consumption, exports and imports of oil by country. Methodology[edit] Below the chart numbers there is specified which position a country holds by the corresponding parameter. Dependent territories, not fully recognized countries and supranational entities are not ranked. Note that data related to one parameter may be more up to date than data related to some other.

Energy Information Administration, International Energy Statistics.Note: Crude oil production represented by production of crude oil including lease condensate. Global crude oil and lease condensate production increased 24%, or over 14 million barrels per day (bbl/d), between 1980 and 2010 (click animation above). Although the Middle East was the largest regional producer and grew by 23% over that period, or over 4 million bbl/d, the region's share of global crude oil production was at 31% in both 1980 and 2010. Central & South America, Africa, and Asia grew most rapidly, increasing their combined share of total crude oil production from 23% in 1980 to 32% in 2010. North America's crude oil production decreased about 1 million bbl/d between 1980 and 2010—the only region with declining crude oil production. Source: U.S. More recently, however, the United States has reversed a decades-long decline in crude oil production. North Dakota.

PBS Frontline (From 2002) While the United States consumes roughly 19 million barrels of oil a day, mostly to power its 200 million automobiles, it produces only about 8 million barrels (or 42 percent) of that total domestically.

PBS Frontline (From 2002)

The other 58 percent -- some 11 million barrels a day -- of our oil has to be imported from other countries. Although the Middle East remains a principal oil supplier for the U.S. market, in recent decades other parts of the world -- West Africa and Central and South America -- have become vitally important as sources of petroleum. Today, three non-Middle East nations -- Mexico, Venezuela and Nigeria -- combine to provide the United States with almost as much oil as the Persian Gulf region provides.

But overall world oil reserves outside of the Middle East appear to be limited, so over the longer term, the United States expects to remain deeply dependent on oil from the Persian Gulf.

Geologists preparing a hole for the explosive charges used in seismic exploration Schematic of different types of oil and natural gas wells Schematic of the basic types of oil and natural gas deposits The search for crude oil begins with geologists who study the structure and history of rock layers below the earth's surface to locate areas that may contain deposits of oil and natural gas. Geologists often use seismic surveys on land and in the ocean to find the right places to drill wells. If a site seems promising, an exploratory well is drilled and tested.
