Gas hydrates collect and store both thermogenic and biogenic methane generated in deep ocean sediments that, over geologic time, forms vast methane repositories. Offshore Gas Hydrates: Origins, Development, and Production presents gas hydrates as an emerging, clean energy source possibly more abundant than all other fossil fuels and especially important for countries geographically and economically restricted from conventional fossil fuel resources. The book explores feasible methods to produce offshore hydrate gas, the means to store and transport the remotely produced gas, new hydrate inhibitors for conventional and hydrate production in ultra-deep waters, instability manifestations of seafloor hydrates, and hydrate roles in complex ecological scenarios. Complementing production and drilling method presentations are computer simulation studies, hydrate field tests, and seismic and logging developments. Offshore Gas Hydrates delivers a well-developed framework for both the oil and gas researcher and corporate engineer to better exploit this future unconventional resource, empowering the oil and gas professional with the latest data and information on sophisticated challenges that offshore hydrates present. Addresses the technical, economic, and environmental problems of producing hydrate gas. Introduces the overlooked and unchartered role of microbes in catalyzing offshore hydrate formations with attendant effects on stability/dissociation. Reviews the latest world-wide field tests, research, and case studies involving seafloor hydrates, inclusive of most known hydrate provinces. Displays two videos within the e-book only: (1) hydrates, carbonates, chemosynthetic communities, and natural hydrocarbon leakages on the seafloor at the Mississippi Canyon hydrate observatory site; (2) hydrate nucleation, migration and self-packing in a laboratory test cell under the influence of anionic surfactants. Extends deep-water hydrate knowledge regarding the hydrate formation and protective cover for microbes within the extreme environment of Mars.

Gas hydrates are ice-like crystalline substances that form a rigid cage of water molecules and entrap hydrocarbon and non-hydrocarbon gas by hydrogen bonding. Natural gas hydrate is primarily composed of water and methane. These are solid, crystalline, ice-like substances found in permafrost areas and deepwater basins around the world. They naturally occur in the pore space of marine sediments, where appropriate high pressure and low temperature conditions exist in an adequate supply of gas (mainly methane). Gas hydrates are considered as a potential non conventional energy resource. Methane hydrates are also recognized as, an influence on offshore platform stability, a major factor in climate change contributing to global warming and a significant contribution to the ocean carbon cycle. The proposed book treats various geophysical techniques in order to quantify the gas hydrate reserves and their impact on environment. The primary goal of this book is to provide the state of art for gas hydrate exploration. The target audiences for this book are non-specialist from different branches of science, graduate students and researchers.

" Although methane hydrates are not recent discoveries, it is only now that their extraction and production are becoming commercially feasible as a major new energy source. They are present offshore in almost every coastal state, and their economic potential for endowing those states with abundant natural gas – in addition to their utility as freshwater resources and as carbon sinks for captured greenhouse gases – is vast. This book presents the first treatment of the legal issues facing the future of offshore methane hydrates, taking into account both proprietary interests and environmental hazards. Starting from law and economics theory as applied to environmental accidents, the book’s analytical framework addresses how best to provide for the opportunities and challenges presented by offshore methane hydrates. Issues and topics include the following: - introduction to the science and technology of offshore methane hydrates; - methane as a green energy source; - research programmes and agendas under way in Japan, South Korea, the United States, Canada, China, and India; - carbon capture and sequestration; - risks – methane emissions, large-scale combustion events, subsea landslides, tsunamis, earthquakes, deep ocean eruptions; - strategies of risk governance – during exploration, development, production and abandonment of the extraction process; - acts that enable seeping and venting of methane; - regulatory compliance as a defense from liability; - grounds for deference to rules of civil liability; - potential impact on anthropogenic climate change; and - private regulation and market-based incentives The analysis compares and contrasts recommended legal policies with existing legal frameworks in relevant international conventions, the European Union, and the United States. Rules of civil liability are reviewed to determine when strict liability or negligence might be efficiently employed in risk governance along with the implementation of public regulations. As a road map to amending and revising existing laws and conventions, this book will be of inestimable practical value to policymakers in supporting the optimal risk governance of the development of methane hydrates. For potential entrepreneurs and operators, this book greatly reduces the legal uncertainty underlying their decision-making and investment decisions. Furthermore, this book enables a broad cross-section of legal practitioners and scholars to engage in this fascinating late arrival to the natural resources law and policy arena. "
