Current member countries
As of January 2019, OPEC has 14 member countries: five in the Middle East (Western Asia), seven in Africa, and two in South America. According to the U.S. Energy Information Administration (EIA), OPEC's combined rate of oil production (including gas condensate) represented 44 percent of the world's total in 2016, and OPEC accounted for 81.5 percent of the world's "proven" oil reserves.
Approval of a new member country requires agreement by three-quarters of OPEC's existing members, including all five of the founders. In October 2015, Sudan formally submitted an application to join, but it is not yet a member.
Qatar left OPEC on 1 January 2019.

- ^ a b One petroleum barrel (bbl) is approximately 42 U.S. gallons, or 159 liters, or 0.159 m3, varying slightly with temperature. To put the production numbers in context, a supertanker typically holds 2,000,000 barrels (320,000 m3), and the world's current production rate would take approximately 56 years to exhaust the world's current proven reserves.

For countries that export petroleum at relatively low volume, their limited negotiating power as OPEC members would not necessarily justify the burdens imposed by OPEC production quotas and membership costs. Ecuador withdrew from OPEC in December 1992, because it was unwilling to pay the annual US$2 million membership fee and felt that it needed to produce more oil than it was allowed under its OPEC quota at the time, although it rejoined in October 2007. Similar concerns prompted Gabon to suspend membership in January 1995; it rejoined in July 2016. In May 2008, Indonesia announced that it would leave OPEC when its membership expired at the end of that year, having become a net importer of oil and being unable to meet its production quota. It rejoined the organization in January 2016, but announced another "temporary suspension" of its membership at year-end when OPEC requested a 5 percent production cut.
Some commentators consider that the United States was a de facto member of OPEC during its formal occupation of Iraq, due to its leadership of the Coalition Provisional Authority in 2003–2004. But this is not borne out by the minutes of OPEC meetings, as no US representative attended in an official capacity.
Since the 1980s, representatives from Egypt, Mexico, Norway, Oman, Russia, and other oil-exporting nations have attended many OPEC meetings as observers. This arrangement serves as an informal mechanism for coordinating policies.
Leadership and decision-making
The OPEC Conference is the supreme authority of the organization, and consists of delegations normally headed by the oil ministers of member countries. The chief executive of the organization is the OPEC Secretary General. The Conference ordinarily meets at the Vienna headquarters, at least twice a year and in additional extraordinary sessions when necessary. It generally operates on the principles of unanimity and "one member, one vote", with each country paying an equal membership fee into the annual budget. However, since Saudi Arabia is by far the largest and most-profitable oil exporter in the world, with enough capacity to function as the traditional swing producer to balance the global market, it serves as "OPEC's de facto leader".
At various times, OPEC members have displayed apparent anti-competitive cartel behavior through the organization's agreements about oil production and price levels. In fact, economists often cite OPEC as a textbook example of a cartel that cooperates to reduce market competition, as in this definition from OECD's Glossary of Industrial Organisation Economics and Competition Law:
International commodity agreements covering products such as coffee, sugar, tin and more recently oil (OPEC: Organization of Petroleum Exporting Countries) are examples of international cartels which have publicly entailed agreements between different national governments.
OPEC members strongly prefer to describe their organization as a modest force for market stabilization, rather than a powerful anti-competitive cartel. In its defense, the organization was founded as a counterweight against the previous "Seven Sisters" cartel of multinational oil companies, and non-OPEC energy suppliers have maintained enough market share for a substantial degree of worldwide competition. Moreover, because of an economic "prisoner's dilemma" that encourages each member nation individually to discount its price and exceed its production quota, widespread cheating within OPEC often erodes its ability to influence global oil prices through collective action.
OPEC has not been involved in any disputes related to the competition rules of the World Trade Organization, even though the objectives, actions, and principles of the two organizations diverge considerably. A key US District Court decision held that OPEC consultations are protected as "governmental" acts of state by the Foreign Sovereign Immunities Act, and are therefore beyond the legal reach of US competition law governing "commercial" acts. Despite popular sentiment against OPEC, legislative proposals to limit the organization's sovereign immunity, such as the NOPEC Act, have so far been unsuccessful.
OPEC often has difficulty agreeing on policy decisions because its member countries differ widely in their oil export capacities, production costs, reserves, geological features, population, economic development, budgetary situations, and political circumstances. Indeed, over the course of market cycles, oil reserves can themselves become a source of serious conflict, instability and imbalances, in what economists call the "natural resource curse". A further complication is that religion-linked conflicts in the Middle East are recurring features of the geopolitical landscape for this oil-rich region. Internationally important conflicts in OPEC's history have included the Six-Day War (1967), Yom Kippur War (1973), a hostage siege directed by Palestinian militants (1975), the Iranian Revolution (1979), Iran–Iraq War (1980–1988), Iraqi occupation of Kuwait (1990–1991), September 11 attacks by mostly Saudi hijackers (2001), American occupation of Iraq (2003–2011), Conflict in the Niger Delta (2004–present), Arab Spring (2010–2012), Libyan Crisis (2011–present), and international Embargo against Iran (2012–2016). Although events such as these can temporarily disrupt oil supplies and elevate prices, the frequent disputes and instabilities tend to limit OPEC's long-term cohesion and effectiveness.
