This statistic shows the oil reserves to production ratio (measured in years) worldwide from 1980 to 2018. In 1980, the ratio of global oil reserves to production, measured in years, was 29.66 Iran's proven oil reserves, estimated at 58.0 billion barrels as of January 1, 1980, represent nearly 10 percent of the world total. 1 At high pre-revolution production rates, the reserves-to-production ratio was about 30:1; in mid-1981, it was more than 100:1. If Iran produces at the current target level of 4.0 million b/d, its proven reserves will last about 40 years.

*Total cost (bbl) includes production cost (also shown), capital spending, gross taxes, and admin/transport costs. Even if a country is blessed with some of the most oil reserves in the world, it may not be able to produce and sell that oil to maximize the potential benefit. Current World Reserves-to-production ratio of Oil: 42.11 Years. What Does Reserves to Production Ratio Mean? A ratio indicating the remaining lifespan of a natural resource. This ratio is expressed in terms of years, and is used in forecasting the future availability of a resource to determine project life, income, employment etc. Reserves to Production Ratio: A ratio indicating the remaining lifespan of a natural resource. This ratio is expressed in terms of years, and is used in forecasting the future availability of a Reserve-to-production ratios may be calculated for individual countries or globally for specific resources. Oil, coal, and gas are the three most important fuels for powering the modern world. These resources are not uniformly distributed over the earth, so some countries have larger reserves than others. Oil reserves. Oil reserves at the end of 2018 totalled 1730 billion barrels, up 2 billion barrels with respect to 2017. The global R/P ratio shows that oil reserves in 2018 accounted for 50 years of current production. Regionally, South & Central America has the highest R/P ratio (136 years) while Europe has the lowest (11 years). The reserves/production ratio or R/P is a method used to assess the size of reserves.The value represents the number of years that current reserves would last if their rate of use did not change. The value of this ratio changes as the size of the reserve changes.

The value of this ratio changes as the size of the reserve changes. At the 2013 rate of production and current reserves estimates, US has almost 12 years of oil production remaining. Excluding oil sands, Canada's reserves to production ratio is 4 years. This is a list of countries by proven oil reserves.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. The ratio of reserves to production – how much oil is left at current rates of output – rose from less than 30 years to 50 years. And that’s despite production having jumped by half. Proven

The World’s Largest Oil Reserves By Country. Proven oil reserves are those that have a reasonable certainty of being recoverable under existing economic and political conditions, with existing technology. Many oil-producing nations provide unaudited claims for their oil reserves.
