There has been a considerable debate over the exploitation of shale gas in the UK. The primary concern is the environmental impact of hydraulic fracturing, specifically in addressing the structural integrity of shale layer and the overlying formation. Shale, like any other geological material has a complex composition and there is need to further understand the mechanics of deformation and damage (its mechanical behaviour). Current computations for mechanical behaviour of shale is based on the assumption that it is homogenous, which is not the case. This limitation is due to inability to observe microscopic mechanisms or micromechanics of shale. The current project aims to address this through acquisition of direct images of deformation and damage in shale by observing the crack/fracture initiation and propagation under load as well as subsequent flow of water, air and noble gases.
