Oil production and consumption by countries
The world leader in oil production is Russia – 10,11 million bbl/d, followed by Saudi Arabia – 9,735 million bbl/d. US is the world leader in oil consumption – 19,0 million bbl/d, followed by China – 10,12 bbl/d.
The world proven oil reserves by 1973 were evaluated at 100 billion bbl tons (570 billion barrels). Thus, they were growing in the past together with oil consumption (within 40 years it reached 32,4 billion bbl/year from 20 billion bbl/year). However, from 1984 annual oil production exceeds the oil proven reserves.
The world oil consumption in 2015 reached 5,7 billion tons per year or 32,7 billion bbl/year.
