Abstract The evolution of fracture geometries caused by asperity damage and gouge formation during the shear significantly affect fluid flow in rock fractures . In this research, a cylindrical sandstone sample was fractured by using the Brazilian splitting test. Fluid flow tests and 3D scanning methods were performed on the fractured sample when it was sheared, to examine how shear-induced alteration of fracture geometries affected the permeability. A simplified modeling algorithm was proposed t...

In areas of broken soft and low-permeability coal, indirect hydraulic fracturing (HF) coal is a technology with great potential to increase coal bed methane (CBM) production. The key to success of the technology is that HFs can cross the coal–rock interface from the roof and propagate into the coal. To this end, this article focuses on the roots that hinder the HFs propagating enough in the coal, that is, the significant inelastic deformation and abundant discontinuities of the coal. Based on CT...

Increasing large-scale development and utilization of new geo-energy sources and geo- resources heralds the need for worldwide implementation of sustainable development. The extreme complexity in recovery conditions, including ultra-low-permeability reservoirs, low-energy-density reserves and high temperatures and high pressures, defines a challenge in efficiently recovering such energy, fuel and mineral resources. Hence, development of efficient mining methods and the related determination of geo-...

Coal bed methane (CBM) is a primary clean energy source found in coal seams. The recovery ratio of CBM is very low, especially with ground extraction, due to the strong adsorption of CH4 on the por...

Abstract Super-critical CO2 enhanced coalbed methane (Sc-CO2-ECBM) and microbially enhanced coalbed methane (MECBM) are environment-friendly technologies that can improve CBM recovery and generation. In this study, a new approach of MECBM based on Sc-CO2 extraction is presented. The Sc-CO2 pretreatment experiments of anthracite and bituminous coal were conducted to produce biomethane. The extracted organics and the changes of coal structure caused by Sc-CO2 were also analyzed to discuss the mech...
