Oil production

Global oil production increased by 380,000 b/d in 2008, or 0.4%, to 81.8 mb/d in 2008

OPEC production increased by 990,000 b/d despite production cuts instituted late in the year, Saudi Arabia saw the largest production increase, with output rising by 400,000 b/d. Russian production fell by 90,000 b/d, the first decline since 1998. OECD production fell by 750,000 b/d, with Mexico registering the world’s largest decline (310,000 b/d).

Methodology

Crude oil production data includes crude oil, shale oil, oil sands and NGLs (natural gas liquids - the liquid content of natural gas where this is recovered separately). It excludes liquid fuels from other sources such as biomass and coal derivatives.

Reserves-to-production (R/P) ratios are available for the world and by region and feature in the Energy charting tool. R/P ratios represent the length of time that those remaining reserves would last if production were to continue at the previous year's rate. It is calculated by dividing remaining reserves at the end of the year by the production in that year.

World oil production tables are in both thousand barrels daily and million tonnes.
