Qa'da 09, 1431, Oct 17, 2010, SPA -- Saudi Arabia will hold a major international energy symposium tomorrow as part of the golden jubilee celebrations of the Organization of Petroleum Exporting Countries (OPEC). An exhibition, in which several local and international petrochemical companies will participate, will also be staged on the sidelines of the three-day celebrations. It will be organized by the Ministry of Petroleum and Mineral Resources and held at the InterContinental Hotel here, according to a press release published today. "The Riyadh-based International Energy Forum (IEF) together with several energy-related local, regional and international organizations will participate in OPEC's 50th anniversary celebrations," said Noe van Hulst, IEF secretary general, who will deliver a speech at the symposium. Saudi Arabia is a major member of the 12-member organization with Algeria, Angola, Ecuador, Iran, Iraq, Kuwait, Libya, Nigeria, Qatar, the UAE and Venezuela. OPEC, which has its secretariat in Vienna, is a permanent intergovernmental organization. In a recent press interview, van Hulst said that a few other major energy events would take place within the next few months from now besides OPEC's golden jubilee celebrations. To this end, he noted that an important energy event, to be held in London on Nov. 22 and 23, will focus on how the physical and financial markets for energy interact and how to regulate the energy market. The event is being organized jointly by the IEF, OPEC and the International Energy Agency (IEA).
