Book Description
In 1972, the Bureau of Mines developed a direct-method test for measuring the gas content of virgin coal core samples for coal mine health and safety considerations. Since that time, approximately 1,500 coal samples from more than 250 coalbeds in 17 States have been collected for gas content determination. The gas content data, when combined with geologic and engineering studies, can be used as a basis for a preliminary estimate of mine ventilation requirements, and to determine if methane drainage in advance of mining should be considered. The data are also critical in delineating coalbed methane resources and in utilization feasibility studies. This report makes the Bureau's extensive data base of gas content data more readily available to the coal and gas industries. The data are presented in tabular form, alphabetically by coalbed name and by State. The components of the total gas content (lost, desorbed, and residual gas) are given, Location (State and county), sample depth, coalbed or formation name, and coal rank are included for geographic and geologic identification.
Advanced Reservoir and Production Engineering for Coal Bed Methane

Book Description
Advanced Reservoir and Production Engineering for Coal Bed Methane presents the reader with design systems that will maximize production from worldwide coal bed methane reservoirs. Authored by an expert in the field with more than 40 years of' experience, the author starts with much needed introductory basics on gas content and diffusion of gas in coal, crucial for anyone in the mining and natural gas industries. Going a step further, chapters on hydrofracking, horizontal drilling technology, and production strategies address the challenges of dewatering, low production rates, and high development costs. This book systematically addresses all three zones of production levels, shallow coal, medium depth coal, and deep coal with coverage on gas extraction and production from a depth of 500 feet to upwards of 10,000 feet, strategies which cannot be found in any other reference book. In addition, valuable content on deep coal seams with content on enhanced recovery, a discussion on CO2 flooding, infra-red heating and even in-situ combustion of degassed coal, giving engineers a greater understanding on how today's shale activities can aid in enhancing production of coal bed for future natural gas production. - Delivers how to recover and degas deeper coal seams while lowering development costs - Addresses both sorption process and irreducible fraction of gas in coal, with examples based on the author's 40 plus years of direct experience - Explains how the same techniques used for production from deep shale activity can produce gas from deep coal seems with the help of enhanced recovery, leading to increased gas production

Book Description
Coal Bed Methane: Theories and Applications, Second Edition, captures the full lifecycle of a coal bed methane well and offers petroleum geologists and engineers a single source for a broad range of coal bed methane (CBM) applications. The vast coal resources in the United States continue to produce tremendous amounts of natural gas, contributing to a diverse range of energy assets. This book addresses crucial technical topics, including exploration and evaluation of coal bed reservoirs, hydraulic fracturing of CBM wells, coal seam degasification, and production engineering and processing, among others. The book also covers legal issues and permitting, along with an economic analysis of CBM projects. This new edition includes information on new and established research and applications, making it relevant for field geologists and engineers, as well as students. - Edited by a team of coal bed methane experts from industry, academia and government with more than 100 years of combined experience in the field - Contains more than 150 figures, photographs and illustrations to aid in the understanding of fundamental concepts - Presents the full scope of improvements in U.S. energy independence, coal mine safety and greenhouse gas emissions

Book Description
Coal and Coalbed Gas: Future Directions and Opportunities, Second Edition introduces the latest in coal geology research and the engineering of gas extraction. Importantly, the second edition examines how, over the last 10 years, research has both changed focus and where it is conducted. This shift essentially depicts "a tale of two worlds"—one half (Western Europe, North America) moving away from coal and coalbed gas research and production towards cleaner energy resources, and the other half (Asia–Pacific region, Eastern Europe, South America) increasing both research and usage of coal. These changes are marked by a precipitous fall in coalbed gas production in North America; however, at the same time there has been a significant rise in coal and coalbed gas production in Australia, China, and India. The driver for higher production and its associated research is a quest for affordable energy and economic security that a large resource base brings to any country like Australia's first large-scale coalbed gas to liquid natural gas projects supplying the demand for cleaner burning LNG to the Asian-Pacific region. Since the last edition of this book, global climate change policies have more forcibly emphasized the impact of methane from coal mines and placed these emissions equal to, or even more harmful than, CO2 emissions from fossil fuels in general. Governmental policies have prioritized capture, use, and storage of CO2, burning coal in new highly efficient low emission power plants, and gas pre-drainage of coal mines. The Organization for Economic Cooperation and Development (OECD) countries and China are also introducing new research into alternative, non-fuel uses for coal, such as carbon fibers, nanocarbons, graphene, soil amendments, and as an unconventional ore for critical elements. New to this edition: Each chapter is substantially changed from the 1st edition including expanded and new literature citations and reviews, important new data and information, new features and materials, as well as re-organized and re-designed themes. Importantly, three new chapters cover global coal endowment and gas potential, groundwater systems related to coalbed gas production and biogenic gas generation as well as the changing landscape of coal and coalbed gas influenced by global climate change and net-zero carbon greenhouse gas emissions. FOREWORD When I reviewed the first edition of this book, my initial thought was, "Do we need another book on coal geology?" and then I read it and realised, "Yes, we need this book" and my students downloaded copies as soon as it was available. So now we come to 2023, and a lot has happened in the past decade. For a different reason we might ask if we still need this book, or even coal geoscientists and engineers, as the world aims for rapid decarbonisation of the energy sector and a reduction of coal as a feedstock for industrial resources, like steel manufacture.
