This book examines select elements, issues and analyses relating to international energy partnerships. Topics discussed include the proposed U.S.-Mexico Transboundary Hydrocarbons Agreement which marks the start of an energy partnership in an area of international waters estimated to contain as much as 172 million barrels of oil and 304 billion cubic feet of natural gas. The main purpose of the partnership would be to lift a moratorium and to jointly develop reservoirs of oil and natural gas, referred to as "transboundary resources," that exist in areas straddling the marine border of both countries. Also discussed are the potential approaches that Europe might employ to diversify its sources of natural gas supply, Russia's role in Europe's natural gas policies, and key factors that could hinder efforts to develop alternative suppliers of natural gas as well as strategies for international co-operation in support of energy development in Pacific island nations.
