This book explores the impact on the Russian gas sector of changes in international gas markets, including the growth of competition and development of new sources of supply. It also assesses how Russian responses, in turn, impact the markets where Russian gas is sold. The volume is structured to reflect the Russian Gas Matrix described in OIES research: the shifting relationship between key elements of supply and demand for Russian gas. It includes chapters on demand for Russian gas in Europe, CIS importing countries, Asia, and the domestic Russian market, as well as analysis of sources of Russian gas supply, including Gazprom, other producers such as Novatek and Rosneft, and imports from Central Asia. It also considers the wider economic context of change in the gas sector, and addresses the key political and economic issues it faces, including the contribution of gas revenues and taxes to the Russian budget, the potential for changes to the structure of the domestic market and the export monopoly, the future of domestic gas prices and the balance of supply among Russian producers. The book aims to provide a detailed update to Jonathan Stern's The Future of Russian Gas and Gazprom (OUP, 2005) and to develop themes raised in Simon Pirani's (ed.), Russian and CIS Gas Markets and their Impact on Europe (OUP, 2009).
