The second component of this paper involved investigating the potential impact that coal seams could have on CO 2 storage in saline formations. A series of hypothetical cases are constructed to investigate the impact of coal seams as (1) a layer within the target aquifer above the injection point, (2) two layers separated by an aquifer above ...

It is generally believed that gas in coal is composed of adsorption gas and free gas. The adsorption process could lead to coal swelling deformation and thus affects gas permeability. Some works indicated that the sorption-induced swelling deformation could be calculated based on the change in coal surface energy (Pan and Connell 2011b ).

Carbon dioxide geological storage involves injecting captured CO2 streams into a suitable reservoir. Subsequent mineral trapping of the CO2 as carbonate minerals is one of the most secure forms of trapping. Injection of CO2 dissolved in water or co-injection of CO2 with water may enhance trapping mechanisms.

1. Introduction [2] The role and importance of geologic nitrogen (nitrogen contained in bedrock) is conspicuously absent from most reviews of global nitrogen cycling dynamics. The Earth's bulk rock nitrogen concentration has been estimated at 1.27 (±1) mg N kg −1 [Allègre et al., 2001], with roughly 20% of the global nitrogen pool tied up in rock [Schlesinger, 1997].

In addition to its sequestration in depleted formations, the injected CO 2 also provides sustained pressure that enhances the production of CH 4, which competes with CO 2 12, 13 for sorption on the internal surface of the reservoirs. Better understanding of the phenomenon entails having two main ingredients.

In this paper, we report unique findings about the interactions between important shale minerals and sorbing gases (CH 4 and CO 2) and associated economic consequences. Where enhanced condensation of CO 2 followed by desorption on clay surface is observed under supercritical conditions, a linear sorption profile emerges for CH 4.

Nanoscale chemical reactions between CO 2 and caprock can cause either opening or sealing of fractures in caprocks, and can affect structural trapping. (3) As injected CO 2 migrates, the free phase CO 2 first displaces brine in pore spaces and is then further displaced by brine, leaving some CO 2 trapped in the pore spaces (residual trapping).
