Explanation:

Launched on September 14, 1960, the Organization of Petroleum Exporting Countries (OPEC) is an intergovernmental organization that aims to centralize the formulation of policies on oil production and sale of member countries.

Currently, OPEC member countries are: Algeria, Angola, Ecuador, Iran, Iraq, Kuwait, Libya, Nigeria, Qatar, Saudi Arabia, United Arab Emirates and Venezuela. Indonesia suspended its membership in January 2009. The OPEC headquarters are located in Vienna, the capital of Austria.

Accordingly we can say that Russia is not part of OPEC.
