Energy analysis on Coalbed Methane (CBM) coupled power systems

Journal of CO2 Utilization, 2017
Abstract Coalbed Methane (CBM) contains 97% of CH4 and very less amount of sulphur. Methane is a very high calorific value (≅55.7 MJ/kg) gas as well as a greenhouse gas, which gets adsorbed on coal beds during coalification. Hence, capture of this CBM gas prior to coal mining not only prevents fire hazard but also the emission of greenhouse gas into ...

Investigations of Stress-Dependent Petrophysical Properties of Coalbed Methane (CBM)

SPE Middle East Oil and Gas Show and Conference, 2009
Abstract The increase of successful exploration and economical importance of coalbed methane makes the understanding of petrophysical properties-stress-dependent more essential. The influences of net stress on porosity, permeability, and reservoir quality index of Australian coalbed methane (CBM) formation are ...

Primary Geology Factors Controlling Coalbed Methane (CBM) Enrichment in Jixi Basin

Applied Mechanics and Materials, 2013
Jixi basin is one of the important coal basins in China. To explore the gas accumulation characteristics and its geological controls, it’s important for further exploration and development of coalbed methane (CBM). The gas content of Jixi Basin is high viable from 4.78 to 11.94 m3/t, indicating high gas content in the north and west but low gas content

Methodologies and Tools for Coalbed Methane (CBM) Field Development Planning Studies

SPE Asia Pacific Oil and Gas Conference and Exhibition, 2011
Abstract Resource plays such as Coalbed Methane (also called Coal Seam Gas) fields typically exhibit a number of unique characteristics that set them apart to other hydrocarbon accumulations. We will argue in this paper that as consequence, conducting effective field development planning studies for CBM resources requires adopting a ...
