In some coalbeds, naturally occurring water pressure holds methane-the main component of natural gas-fixed to coal surfaces and within the coal. In a coalbed methane (CBM) well, pumping water from the coalbeds lowers this pressure, facilitating the release of methane from the coal for extraction and use as an energy source. Water pumped from coalbeds during this process-CBM 'produced water'-is managed through some combination of treatment, disposal, storage, or use, subject to compliance with federal and state regulations. CBM produced water management can be challenging for regulatory agencies, CBM well operators, water treatment companies, policy makers, landowners, and the public because of differences in the quality and quantity of produced water; available infrastructure; costs to treat, store, and transport produced water; and states' legal consideration of water and produced water. Some states consider produced water as waste, whereas others consider it a beneficial byproduct of methane production. Thus, although current technologies allow CBM produced water to be treated to any desired water quality, the majority of CBM produced water is presently being disposed of at least cost rather than put to beneficial use. This book specifically examines the Powder River, San Juan, Raton, Piceance, and Uinta CBM basins in the states of Montana, Wyoming, Colorado, New Mexico, and Utah. The conclusions and recommendations identify gaps in data and information, potential beneficial uses of CBM produced water and associated costs, and challenges in the existing regulatory framework.

Bridging the gap in expertise between coal and coalbed gas, subfields in which opportunities for cross training have been nonexistent, Coal and Coalbed Gas sets the standard for publishing in these areas. This book treats coal and coalbed gas as mutually inclusive commodities in terms of their interrelated origin, accumulation, composition, distribution, generation, and development, providing a balanced understanding of this energy mix. Currently considered a non-renewable energy resource, coalbed gas, or coalbed methane, is a form of natural gas extracted from coal beds. In recent years, countries have begun to seek and exploit coal for its clean gas energy in an effort to alleviate environmental issues that come with coal use, making a book on this topic particularly timely. This volume takes into account processes of coalification, gasification, and storage and reservoir characterization and evaluation and looks at water management and environmental impacts as well. - Covers environmental issues in the development of coalbed gas - Includes case studies, field guides and data, examples, and analytical procedures from previous studies and investigations - Accessible by a large multidisciplinary market by one of the world's foremost experts on the topic

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

This book Understanding Pore Space through Log Measurements deals with porosity, insight on pore shape connectedness, grain size, grain aspect ratio, permeability etc. Most of the published literature is focused on permeability from log measurements and log analytic techniques for porosity and fluid saturation determination. On the other hand, this book aims at looking at porosity distribution, pore shape, and pore connectedness using log measurements and thus bringing pore space into focus. A compilation of available knowledge from this perspective will lead the reader to better understanding of reservoir characterization takeaways, which exploration and exploitation managers and workers will be looking for. - Offers insight into influence of pore attributes on macroscopic pore space descriptors - Grain characters that influence the properties of the pore space - Guides on how to best model the inversion of log data into these attributes

In "Carbon Capture - Utilization and Storage: Climate Change Mitigation," the urgent battle against climate change takes center stage as the world grapples with the pressing need to reduce anthropogenic carbon dioxide emissions. Delving into the intricate science behind Carbon Capture, Utilization, and Storage (CCUS), this book navigates the complex landscape of strategies aimed at trapping emitted CO2 and preventing its release into the atmosphere. From post-combustion to pre-combustion methods, readers are immersed in a world where cutting-edge technologies intersect with environmental necessity. As the global community strives to honor the mandates of the Paris Agreement, the author explores the potential of CCUS to pave the way for a carbon-neutral future. Despite challenges surrounding cost and commercial viability, a glimmer of hope emerges as integrated CCUS systems gain traction around the world. From the United States to China, these systems offer a glimpse into a future where carbon capture and utilization become integral components of sustainable energy production. With a focus on clarity and accessibility, this book aims to educate undergraduates, researchers, and policymakers alike on the vital role CCUS plays in the fight against climate change. For those seeking a comprehensive understanding of this pivotal technology, "Carbon Capture Utilization and Storage" serves as an indispensable guide into the realm of environmental stewardship and innovation.
