OPEC Statute

The OPEC members list is divided into Founder Members, Full Members, and Associate Members. Founder Members include the original five countries. Full Members are those accepted in after submitting an application.

The OPEC Statute asserts that “any country with a substantial net export of crude petroleum, which has fundamentally similar interests to those of Member Countries, may become a Full Member of the Organization, if accepted by a majority of three-fourths of Full Members, including the concurring votes of all Founder Members.”

Associate Members are countries that do not meet the bar for full membership but can be admitted under special conditions.

OPEC+, pronounced as ‘OPEC plus,’ is considered an extension of the OPEC members list when the organization makes production cut deals with non-OPEC countries.

The OPEC+ Alliance Members List includes:

In September 2016, the organization faced the prospect of lower oil prices without a production cut. This incentivized the group to make headway toward its first production cut since oil’s price collapse during the 2008 financial crisis.

Eventually, one million barrels per day were dropped from production, agreed to in November 2016. Russia and 10 other non-OPEC members also agreed to the cut. Nonetheless, other producers were expected to offset the cut to take more market share, notably the US shale industry. Libya and Nigeria also did not participate. Indonesia forfeited its membership rather than agreeing to a production cut.

From then on, any OPEC agreement with non-OPEC members would be referred to as OPEC+.

Most notably, this included the following deals and strategic responses:

Non-OPEC Oil Producers

Some of the major world players that are non-OPEC members but who produce oil include:

Non-OPEC countries usually have high oil demands and can’t export most of their production. Because of this, they have minimal influence on crude oil prices. However, the recent discovery of shale oil and gas has boosted their market share. One such example is the USA, which has increased its exports.

OPEC Purpose

The objective of the OPEC is stated in the rules: “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.”

However, critics argue that the largest OPEC members essentially run a cartel that work together to control the market while retaining many legal protections. There is also a question around transparency with the limited number of OPEC members also controlling the flow of oil information and statistics.

Their role becomes even more important during major geopolitical events, such as the 2022 Russia-Ukraine war. The conflict led to a significant decrease in access to crude oil and other oil products for many European countries. The result was increased demand for supplies in OPEC countries and a surge in prices.
