The Pricing of natural gas has remained a central issue since its emergence an energy resource. Whether gas is for domestic use or international trade, the primary issues of price, profitability and politics are intrinsically intertwined. With the emergence of unconventional supply - shale gas – these underlying issues have become more obvious and complicated. This book traces the evolution of cross border gas pricing concepts and details the different pricing regimes for international gas trade. The theory and practice of uniform pricing were investigated within the gas industry. So far, no book has considered the application of uniform pricing in international gas trade. This unique endeavour questions whether a geopolitical attempt to reconcile pricing regimes in international gas trade is economically feasible. It is an outstanding contribution to the economics and geopolitics of natural gas and crude oil trade.
