Journal ArticleDOI
Pore structure and its impact on CH4 adsorption capacity and flow capability of bituminous and subbituminous coals from Northeast China
TL;DR: In this article, the surface fractals of pore surface were analyzed with surface fractal dimensions and the results showed that the more irregular surface, the more inhomogeneous pore structures is, meaning more surface area and then stronger adsorption capability.
Journal ArticleDOI
Geological controls on prediction of coalbed methane of No. 3 coal seam in Southern Qinshui Basin, North China
TL;DR: In this article, coalbed methane (CBM) in Southern Qinshui basin (SQB), North China, was analyzed using coal petrology analysis, proximate analysis and methane adsorption/desorption, and the results showed that the coals from the SQB contain 0.59-3.49% moisture, 3.5-15.54% ash yield, 73.92% fixed carbon and 2.4-81.4% inertinite.
Journal ArticleDOI
Permeability evolution in fractured coal — Combining triaxial confinement with X-ray computed tomography, acoustic emission and ultrasonic techniques
Yidong Cai,Dameng Liu,Jonathan P. Mathews,Zhejun Pan,Derek Elsworth,Yanbin Yao,Junqian Li,Xiaoqian Guo +7 more
TL;DR: In this article, the authors explore the interactions of stress and damage that contribute to changes in coal permeability through imaging with X-ray computed tomography (X-ray CT), acoustic emission (AE) profiling together with the concurrent measurement of P-wave velocities.
Journal ArticleDOI
Advanced characterization of pores and fractures in coals by nuclear magnetic resonance and X-ray computed tomography
TL;DR: In this article, the authors demonstrated capabilities of low-field nuclear magnetic resonance (NMR) and microfocus X-ray computed tomography (μCT) in advanced, nondestructive, and quantitative characterization of pore types, producible porosity, pore structure, and spatial disposition in coals.
Journal ArticleDOI
Petrophysical characterization of oil-bearing shales by low-field nuclear magnetic resonance (NMR)
TL;DR: In this paper, two sets of NMR measurements were performed to reveal the porosity, permeability, movable fluid volume and pore size distribution (PSD) of oil-bearing shales.
