Pore Structure and Gas Adsorption in Coal and Tight Reservoirs
This community investigates the microscopic architecture of coal, shale, and tight sandstone to understand how these rocks store and release natural gas, oil, and carbon dioxide.
The work centers on characterizing pore structure, size distribution, and fractal characteristics using mercury intrusion porosimetry, nuclear magnetic resonance, and machine learning models. A significant portion of the research focuses on coalbed methane and shale gas reservoirs, specifically within the Ordos, Sichuan, and other basins in China. Studies examine how pore geometry controls gas adsorption capacity and permeability. Additionally, the community addresses coal safety issues, including the mechanisms of spontaneous combustion and the development of dust suppression and fire prevention materials. The recurring methods involve multi-scale imaging and simulation to link microscopic pore networks with macroscopic reservoir quality and flow behavior.
The community is most heavily represented in research tracked for Mercury, accounting for 2.0% of all mercury-related papers, with 2,582 papers in this group. It also constitutes 0.5% of helium research (477 papers) and 0.4% of carbon research (3,457 papers).
The community comprises 20,657 papers, published primarily in Fuel, Fuel Processing Technology, and Carbon.
Recent work continues to focus on characterizing pore networks in low-permeability rocks using advanced segmentation models and investigating the use of nanofluids and foams to enhance methane recovery and suppress coal fires.
