Facts:The purpose of OPEC for members
is to "coordinate and unify the petroleum policies of its Member Countries and ensure the stabilization of oil markets in order to secure an efficient, economic and regular supply of petroleum to consumers, a steady income to producers and a fair return on capital for those investing in the petroleum industry."
OPEC member countries monitor the market and decide collectively to raise or lower oil production in order to maintain stable prices and supply.
A unanimous vote is required on raising or lowering oil production.
Each member country controls the oil production of its country, but OPEC aims to coordinate the production policies of member countries.
Oil and energy ministers from OPEC member countries usually meet twice a year to determine OPEC's output level. They also meet in extraordinary sessions whenever required.
