Research

Characterisation of seismic wave propagation through fractured media. The overarching goal is to gain a better understanding of how the acoustic properties of rocks change during the development of fracture networks. Laboratory experimentation is to be combined with numerical modelling as a initial validation of observed phenomena. The initial focus of research is directed towards the information stored within the coda or diffuse portion of the waveform, and the application of a method know as Coda Wave Interferometry (CWI), [3]. 

A further research direction is proposed to analyse the feasibility of using passive sources, to retrieve the impulse response functions. This would then allow CWI to be applied to the time-lapse impulse response functions [2]. Following on from this the estimation of the location of scatterers (in this case fracture plains) my be attempted as demonstreated by [1].
