largest oil reserves in world
Nigeria - 37.07 Billion Barrels. Although Libya has more reserves, there were 37.2 billion barrels of proven oil reserves in Nigeria, ranking the country as the largest oil producer in Africa and the 10th largest in the world. At current rates this would be 45 years of supply if no new oil was found.
Three years ago the US was behind Russia, Canada and Saudi Arabia.. More than half of the US's remaining oil reserves are in unconventional shale oil, Rystad Energy data show. Texas alone holds more than 60bn barrels of shale oil.
