Numerical analysis of improvements to CO2 injectivity in coal seams through stimulated fracture connection to the injection well (2020)
Journal Article
Chen, M., Hosking, L. J., Sandford, R. J., & Thomas, H. R. (in press). Numerical analysis of improvements to CO2 injectivity in coal seams through stimulated fracture connection to the injection well. Rock Mechanics and Rock Engineering, https://doi.org/10.1007/s00603-020-02088-1

This work presents a hybrid discrete fracture-dual porosity model of compressible fluid flow, adsorption and geomechanics during CO2 sequestration in coal seams. An application of the model considers the influence of hydraulic fractures on CO2 transp...

Dual porosity modelling of the coupled mechanical response of coal to gas flow and adsorption (2019)
Journal Article
Chen, M., Hosking, L. J., Sandford, R. J., & Thomas, H. R. (2019). Dual porosity modelling of the coupled mechanical response of coal to gas flow and adsorption. International Journal of Coal Geology, 205, 115 - 125. https://doi.org/10.1016/j.coal.2019.01.009

This paper presents the inclusion of explicit dual poroelastic mechanical behaviour as part of an existing dual porosity numerical model of multiphase, multicomponent chemical-gas transport. The dual poroelastic framework employed considers the pore... Read More about Dual porosity modelling of the coupled mechanical response of coal to gas flow and adsorption.

Deep coal reserves represent a valuable resource, both in terms of their potential for the sequestration of anthropogenic carbon dioxide and for energy extraction through underground coal gasification (UCG). This paper looks at the current field and... Read More about Deep ground and energy: Carbon sequestration and coal gasification.
