MOSCOW (Sputnik) — According to the ASB, in 2015, the top three crude oil producing countries were Saudi Arabia with 10.19 million barrels per day (mb/d), which was followed by Russia with 10.11 mb/d and the United States with 9.43 mb/d.
"In 2015… Saudi Arabia displaced Russia in the top position [among oil producing states] for the first time since 2005," OPEC said in its Annual Statistical Bulletin (ASB).
OPEC has been publishing the ASB, which focuses on statistical information about oil exports, imports and output, as well as infrastructure for oil production and transportation since 1965. The ASB focuses on OPEC member states, comprising Algeria, Angola, Ecuador, Indonesia, the Islamic Republic of Iran, Iraq, Kuwait, Libya, Nigeria, Qatar, Saudi Arabia, the United Arab Emirates and Venezuela, but also provides statistical information about non-OPEC members.
