TL;DR: In 2015, China produced 17.1 billion cubic meters (BCM) of methane sourced from coal seams in 2015, of which 4.43 BCM is from wells drilled from the surface.

TL;DR: In this article, the authors examined the impacts of supercritical fluid and subcooled liquid transport on energy efficiency and cost of CO2 transport in a commercial process simulator, ASPEN PLUS 10.1.

TL;DR: In this paper, the occurrence of coal seams in Huaibei coalfield is investigated by combining systematic analyses on the occurrence and formation of coalbed methane reservoirs, and it is shown that coal seams are distributed in north-south tectonic blocks and east-west tectonics zones.

TL;DR: In this paper, the authors present experimental investigations on CO 2 /CH 4 binary gas flow in bulk coal under controllable stress conditions, focusing on sorption-induced swelling/shrinkage and gas permeability associated with CO 2 -sequestration enhanced coalbed methane (CO 2 -ECBM) recovery.

TL;DR: In this article, a combined investigation of geophysical logging data and well tests from coal reservoirs of Huainan and Huaibei coalfields in China was studied by a combined study of coal structures and the associated coal permeability, where a large amount of the site observations on coal sections of mining faces and macroscopic investigations on textures of drilling coal cores were carried out, providing experimental information for classification of coal structure.
