We spend most of our lives calculating how to avoid, mitigate or limit our exposure to risks. It is not entirely different in the Oil and Gas Industry. The industry is inherently exposed to different genus of risks as exemplified by numerous accidents, oil spills, blow-outs, natural calamities among others. This book examines different modes deployed by the oil and gas industry especially in United States Continental Shelf and United Kingdom Continental shelf to manage and transfer these risks. The book examines the different contractual mechanisms used to allocate risks and how such mechanisms operate. With in-depth analysis, Patson compares the application of such risk allocation mechanisms in two leading jurisdictions of US and UK and how their Courts have interpreted them over the years. This book is of great value to the understanding of contractual risk management in the oil and gas industry.
