Book excerpt: A method of gasification of coal in deep, thin seams by using controlled bending subsidence to confine gas flow to a region close to the unconsumed coal face. The injection point is moved sequentially around the perimeter of a coal removal area from a production well to sweep out the area to cause the controlled bending subsidence. The injection holes are drilled vertically into the coal seam through the overburden or horizontally into the seam from an exposed coal face. The method is particularly applicable to deep, thin seams found in the eastern United States and at abandoned strip mines where thin seams were surface mined into a hillside or down a modest dip until the overburden became too thick for further mining.

This book was released on 2016-10-05 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 was released on 2012-12-06 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Seminar on Improved Techniques for the Extraction of Primary Forms of Energy was organized by the United Nations Economic Commission for Europe (ECE) and held at Vienna from 10 to 14 November 1980 at the invitation of the Austrian Government.* Mr. H. Sparker, a Director of the Austrian Mineral-Oil Administration (OeMV) , was elected chairman of the seminar. Mr. V. Zanchev (Bulgaria), Mr. J. Medaets (Belgium) and Mr. S. Doleschall (Hungary) were elected chairmen of working meetings 1, 2 and 3 respectively. At the invitation of the Austrian Mineral-Oil Administration (OeMV), the parti cipants inspected the steam-injection installations in the Maustrenk and explora tory fields and the oil and gas production facilities in the north Vienna basin. In a statement on behalf of the Austrian Government at the opening meeting, Mr. A. Nussbaumer, Secretary of State, emphasized that remedies for the difficult energy situation depended in the long run on the contribution of scientific and technical research; whence the significance of the seminar. Efforts now in progress must be directed towards more rational use, by means of existing or new techniques, of proved resources of fossil fuels. The participants would, he hoped, devote their discussions to more effective technologies which would enable the recovery factor to be improved with fewer repercussions on the environment. Austria in general, and its Alpine regions in particular, were "rich in poor mineral deposits", and consequently public undertakings, universities and industrial research institutions had a very real interest in the seminar's work.

Available in PDF, EPUB and Kindle. Book excerpt: Coal mining continues to make advances, especially in the areas of safety and environmental protection as a result of mining. This book contains nine peer-reviewed articles on green coal mining that address most of the important issues associated with improving coal mining. These issues include the protection of water above coal mines, both surface and ground water, and the subsidence that occurs during and after mining with methods to limit it and methods of rehabilitation. Additional issues include mine entry and production area support and methods to control gas emissions.

Available in PDF, EPUB and Kindle. Book excerpt: The book deals with development of comprehensive computational models for simulating underground coal gasification (UCG). It starts with an introduction to the UCG process and process modelling inputs in the form of reaction kinetics, flow patterns, spalling rate, and transport coefficient that are elaborated with methods to generate the same are described with illustrations. All the known process models are reviewed, and relative merits and limitations of the modeling approaches are highlighted and compared. The book describes all the necessary steps required to determine the techno-economic feasibility of UCG process for a given coal reserve, through modeling and simulation.
