This book provides an update the development of natural gas in the Gulf countries nearly ten years after the publication of the OIES Gas Programme book on Natural Gas Markets in the Middle East and North Africa. The book comprises in-depth studies of a smaller set of countries, but those of critical regional and international importance to the future of gas: Qatar, Iran, Oman, Saudi Arabia, UAE, Kuwait, Iraq and Bahrain. Over the past decade, Gulf gas production and demand have expanded rapidly, and the next decade is likely to see further major expansions. The only substantial increase in LNG exports in the 2010s was from Qatar and a smaller, but still very significant, increase is planned for the 2020s. This book finds that the Gulf will play a substantial role in the expansion of global gas supply and demand at least until 2030, and probably beyond, and will therefore remain an extremely important region for gas and energy researchers over the next decade.
