TL;DR: In this paper, the porosity and pore accessibility of coal and shale samples were studied with respect to their porosity, and the results demonstrate that there is a major difference in mesopore (2-50 nm) size distribution between the coal and the shale samples, while there was a close similarity in micropore (<2 nm).

TL;DR: In this article, coal quality and petrographic composition of the coals were determined to study their relationships to the volume of CO2 and CH4 that could be sorbed into the coal.

TL;DR: In this paper, the authors evaluated the feasibility of storing CO2 in geologic formations as a means to mitigate global climate change, and showed that CO2 is adsorbed preferentially over methane (CH4) onto organic materials and clay minerals.

TL;DR: The Seelyville coal Member of the Linton Formation (Pennsylvanian) in Indiana was studied to understand variations in pore characteristics within a coal seam at a single location and compare these variations with changes occurring between the same coal at different locations as discussed by the authors.

TL;DR: A suite of simulations that use a simple hydrogeologic-geomechanical model to assess what hydro geologic conditions promote or deter induced seismic events within the crystalline basement across the midcontinent find the presence of a confining unit beneath the injection reservoir horizon had the single largest effect in preventing induced seismicity within the underlying crystalline floor.
