Testing a New Tool That Illuminates Tiny Fractures in Coal

Research Spotlight—

A computational model outperforms a widely used microcomputed tomography imaging method in characterizing coal fractures.

Tiny micrometer-scale fractures, or “cleats,” permeate coal beds and create networks that often harbor a form of natural gas known as coal seam gas. Coal seam gas consists primarily of methane and is extracted for energy production in a growing number of countries, including the United States.

Coal seam gas has generated controversy in certain regions, with some raising questions about its potential environmental effects. This has created interest in applying advanced characterization methods to better understand gas production from these resources and control its environmental impacts. A new paper by Jing et al. validates a new strategy to advance understanding of coal cleat networks, which is key to modeling the flow of gas through the tiny cracks....more
