Highlights: We demonstrate gas hydrate powder formation for the first time. Hydrate volume fraction can be as high as 95% with fluidity features. The new anti-agglomerant shows kinetic inhibition effect. We propose a mechanism for the formation of hydrate powders. Abstract: Gas hydrates may plug hydrocarbon flowlines even at low hydrate volume fraction due to agglomeration. Anti-agglomeration is perhaps the most effective approach for flow assurance. An effective anti-agglomerant (AA) can prevent gas hydrate particles from sticking together by lowering of the water–oil interfacial tension and increase of the contact angle of water on hydrate surface. In a recent work, we have introduced a new AA formulation which is effective; it forms hydrate slurry over a broad range of oil to water ratio. In this study, we introduce a modified chemical formulation effective at extreme conditions when hydrate powders are formed from two different gases. The formation of hydrate powders has not been reported in the literature. The powders flow readily in rocking cells. The hydrate fraction can be as high as 95% with fluidity behavior. The AA effectiveness reported in this study is much higher than the past work. A new anti-agglomeration mechanism is also proposed. The gas hydrate powder formation may have applications not only in flow assurance, but also in energy storage.

Hydrate research has expanded substantially over the past decade, resulting in more than 4,000 hydrate-related publications. Collating this vast amount of information into one source, Clathrate Hydrates of Natural Gases, Third Edition presents a thoroughly updated, authoritative, and comprehensive description of all major aspects of natural gas clathrate hydrates. What’s New in the Third Edition? This new edition of a bestseller offers updated information on the clathrate hydrate compounds discovered in the past decade, provides a balance between experimental and theoretical perspectives, and incorporates two software programs that can be downloaded from the CRC press website. It also presents case studies on low dosage hydrate inhibitor prevention and hydrate drilling in nature, phase equilibrium data and kinetic models, and descriptions of the paradigm change in flow assurance to risk management. Other new material discusses the paradigm transition from hydrate reservoir assessment to reservoir production and summarizes the in situ conditions for hydrates in the permafrost and oceans. With this modern account of clathrate hydrates, you will acquire a fresh perspective on both new and old theories and data, hopefully leading you to pursue exciting research directions and practical applications.

The precipitation and deposition of solids are a major challenge in the production of oil and gas. Flow assurance solids are formed because of unavoidable changes in temperature, pressure and composition of the oil-gas-water flowstream, from reservoir conditions to processing conditions. The advent of subsea production and the increased exploitation of heavy crudes have made flow assurance issues dominant in ensuring efficient and safe exploitation of hydrocarbon assets. Five troublesome flow assurance solids are described in the book: asphaltene, paraffin wax, natural gas hydrate, naphthenate and inorganic scale. These big-five solids are presented in stand-alone chapters. Each chapter is designed to be readable without clutter. Derivations of equations and descriptions of supporting details are given in several appendices. The book is intended for professional engineers and natural scientist working in E&P companies, engineering companies, service companies and specialized companies. An understanding of the big-five solids is required throughout the lifetime of oil and gas assets, from early development to abandonment. The technical, safety and environmental risks associated with deposition problems in near-wellbore formations, production tubing, wellhead equipment, flowlines and processing facilities, are relevant for decisions in the oil and gas industry and in outside regulatory and financial entities.

Offshore Pipelines covers the full scope of pipeline development from pipeline designing, installing, and testing to operating. It gathers the authors' experiences gained through years of designing, installing, testing, and operating submarine pipelines. The aim is to provide engineers and management personnel a guideline to achieve cost-effective management in their offshore and deepwater pipeline development and operations. The book is organized into three parts. Part I presents design practices used in developing submarine oil and gas pipelines and risers. Contents of this part include selection of pipe size, coating, and insulation. Part II provides guidelines for pipeline installations. It focuses on controlling bending stresses and pipe stability during laying pipelines. Part III deals with problems that occur during pipeline operations. Topics covered include pipeline testing and commissioning, flow assurance engineering, and pigging operations. This book is written primarily for new and experienced engineers and management personnel who work on oil and gas pipelines in offshore and deepwater. It can also be used as a reference for college students of undergraduate and graduate levels in Ocean Engineering, Mechanical Engineering, and Petroleum Engineering. * Pipeline design engineers will learn how to design low-cost pipelines allowing long-term operability and safety. * Pipeline operation engineers and management personnel will learn how to operate their pipeline systems in a cost effective manner. * Deepwater pipelining is a new technology developed in the past ten years and growing quickly.
