This paper seeks to identify the next wave of major oil and gas pipeline construction projects around the world, assessing which countries are likely to be able to turn their plans for new pipelines into real, bankable projects. It is not a comprehensive, or exhaustive, list of new pipeline projects. There is no shortage of new oil and gas pipeline proposals that are keeping project sponsors, industry analysts and conference organisers busy. Many of them are grand in their ambition, many seek to meet the political ends of their sponsors, many cross several international borders, and all will compete for capital and resources. Many of tomorrow’s oil and gas supplies are being developed in areas that are remote from existing infrastructure, far from markets or export terminals. Tomorrow’s big, new hydrocarbons consumers live in countries that are only just beginning to develop their oil and gas import and transmission infrastructures, while traditional markets are stagnating. Politics, too, is playing its part, as old alliances are tested and both buyers and sellers seek security of supply and greater diversification.
