Offshore Gas Hydrates by Rudy Rogers Pdf

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.

Exploration of Gas Hydrates by Naresh Kumar Thakur,Sanjeev Rajput Pdf

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.

Environmental Hazards from Offshore Methane Hydrate Operations by Roy Andrew Partain Pdf

" 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. "

Gas Hydrates by J.-P. Henriet,Jürgen Mienert Pdf

From a geological perspective, gas hydrates are an important feature of the shallow geosphere. If current estimates are correct, gas hydrates contain more potential fossil fuel energy than is present in conventional oil, gas and coal deposits, although it is uncertain how much of this can be exploited. They are also geological agents that affect the physical, geophysical and geochemical properties of sediments. Oceanic gas hydrates are increasingly recognized as a major potential hazard for the stability of offshore structures in various deep-water hydrocarbon provinces. The possibility also exists that a large release of methane from gas hydrates may have a significant impact on the radiative properties of the atmosphere and thus influence global climate: past, present and future. Following an introduction and overviews, this book covers analysis and modelling of hydrate formation; exploration strategy and reservoir evaluation; regional case studies; relevance to margin stability and climate change. Hydrate research informatiloln is presented from the USA, Russia, South Asia and the European Union.

Natural gas, composed mostly of methane, is the cleanest of all the fossil fuels, emitting 25-50% less carbon dioxide than either oil or coal for each unit of energy produced. In recent years, natural gas supplied approximately 20-25% of all energy consumed in the United States. Methane hydrate is a potentially enormous and as yet untapped source of methane. The Department of Energy's Methane Hydrate Research and Development Program has been tasked since 2000 to implement and coordinate a national methane hydrate research effort to stimulate the development of knowledge and technology necessary for commercial production of methane from methane hydrate in a safe and environmentally responsible way. Realizing the Energy Potential of Methane Hydrate for the United States evaluates the program's research projects and management processes since its congressional re-authorization in 2005, and presents recommendations for its future research and development initiatives.

World Atlas of Submarine Gas Hydrates in Continental Margins by Jürgen Mienert,Christian Berndt,Anne M. Tréhu,Angelo Camerlenghi,Char-Shine Liu Pdf

This world atlas presents a comprehensive overview of the gas-hydrate systems of our planet with contributions from esteemed international researchers from academia, governmental institutions and hydrocarbon industries. The book illustrates, describes and discusses gas hydrate systems, their geophysical evidence and their future prospects for climate change and continental margin geohazards from passive to active margins. This includes passive volcanic to non-volcanic margins including glaciated and non-glaciated margins from high to low latitudes. Shallow submarine gas hydrates allow a glimpse into the past from the Last Glacial Maximum (LGM) to modern environmental conditions to predict potential changes in future stability conditions while deep submarine gas hydrates remained more stable. This demonstrates their potential for rapid reactions for some gas hydrate provinces to a warming world, as well as helping to identify future prospects for environmental research. Three-dimensional and high-resolution seismic imaging technologies provide new insights into fluid flow systems in continental margins, enabling the identification of gas and gas escape routes to the seabed within gas hydrate environments, where seabed habitats may flourish. The volume contains a method section detailing the seismic imaging and logging while drilling techniques used to characterize gas hydrates and related dynamic processes in the sub seabed. This book is unique, as it goes well beyond the geophysical monograph series of natural gas hydrates and textbooks on marine geophysics. It also emphasizes the potential for gas hydrate research across a variety of disciplines. Observations of bottom simulating reflectors (BSRs) in 2D and 3D seismic reflection data combined with velocity analysis, electromagnetic investigations and gas-hydrate stability zone (GHSZ) modelling, provide the necessary insights for academic interests and hydrocarbon industries to understand the potential extent and volume of gas hydrates in a wide range of tectonic settings of continental margins. Gas hydrates control the largest and most dynamic reservoir of global carbon. Especially 4D, 3D seismic but also 2D seismic data provide compelling sub-seabed images of their dynamical behavior. Sub-seabed imaging techniques increase our understanding of the controlling mechanisms for the distribution and migration of gas before it enters the gas-hydrate stability zone. As methane hydrate stability depends mainly on pressure, temperature, gas composition and pore water chemistry, gas hydrates are usually found in ocean margin settings where water depth is more than 300 m and gas migrates upward from deeper geological formations. This highly dynamic environment may precondition the stability of continental slopes as evidenced by geohazards and gas expelled from the sea floor. This book provides new insights into variations in the character and existence of gas hydrates and BSRs in various geological environments, as well as their dynamics. The potentially dynamic behavior of this natural carbon system in a warming world, its current and future impacts on a variety of Earth environments can now be adequately evaluated by using the information provided in the world atlas. This book is relevant for students, researchers, governmental agencies and oil and gas professionals. Some familiarity with seismic data and some basic understanding of geology and tectonics are recommended.
