Twice a year, or more frequently if required, the Oil and Energy Ministers of the OPEC Members meet to decide on the Organization's output level, and consider whether any action to adjust output is necessary in the light of recent and anticipated oil market developments.
OPEC's eleven Members collectively supply about 40 per cent of the world's oil output, and possess more than three-quarters of the world's total proven crude oil reserves. More details can be found in the FAQ on OPEC, and in the sections on the individual Member Countries, which feature tables with selected oil, gas and economic data.
