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.

This book introduces readers to experimental techniques of general utility that can be used to practically and reliably determine nucleation rates. It also covers the basics of gas hydrates, phase equilibria, nucleation theory, crystal growth, and interfacial gaseous states. Given its scope, the book will be of interest to graduate students and researchers in the field of hydrate nucleation. The formation of gas hydrates is a first-order phase transition that begins with nucleation. Understanding nucleation is of interest to many working in the chemical and petroleum industry, since nucleation, while beneficial in many chemical processes, is also a concern in terms of flow assurance for oil and natural gas pipelines. A primary difficulty in the investigation of gas hydrate nucleation has been researchers’ inability to determine and compare the nucleation rates of gas hydrates across systems with different scales and levels of complexity, which in turn has limited their ability to study the nucleation process itself. This book introduces readers to experimental techniques that can be used to practically and reliably determine the nucleation rates of gas hydrate systems. It also covers the basics of gas hydrates, phase equilibria, nucleation theory, crystal growth, and interfacial gaseous states. Given its scope, the book will be of interest to graduate students and researchers in the field of hydrate nucleation.

Gas Hydrates are crystalline compounds formed as a result of the combination of certain molecule sizes and water under suitable pressure and temperature conditions. Though gas hydrates resemble ice, they are formed at temperatures well above the freezing point. As a result, large quantities of gas hydrates exist in sub-sea sediments and permafrost regions, thus possessing many interesting properties such as a preference for large, round molecules and high latent heat. This definitive text, while providing an absorbing overview on gas hydrates, their properties and potential applications (for example, gas separation, storage and transport, heat storage, source of energy, etc.), also places special emphasis on flow assurance and how it can be used to prevent gas hydrates problems in oil and gas transport pipelines. Gas Hydrates and Flow Assurance also covers experimental techniques in determining gas hydrate phase boundary in bulk and porous media, thermodynamic modelling and various predictive techniques, and novel techniques that tackle gas hydrate and flow assurance problems. Real-life case studies are also included for discussion.

This book offers a straightforward, informative guide to the chemicals used for gas hydrate formation and inhibition, providing the reader with the latest information on the definition, structure, formation conditions, problems, and applications of gas hydrates. The authors review not only the inhibitors used to prevent or mitigate hydrate formation, but also the conditions under which it is necessary to form hydrates quickly, which require the use of promoters. Various promoters are discussed, including their specifications, functions, advantages and disadvantages. The possibility of using natural reservoirs of gas hydrate as an energy source is also considered. Lastly, due to the difficulty of conducting experiments that reflect all conditions and concentrations, the book presents a number of models that can predict the basic parameters in the presence of the chemicals. Given its scope, the book will be of interest to professionals working in this field in an industrial context, as well as to researchers, undergraduate and graduate students of chemical engineering.
