Spatial constrained inverse rock physics modelling

Rock physics characterization of shale reservoirs: a case study

Unconventional resources are typically very complex to model, and the production from this type of reservoirs is influenced by such complexity in their microstructure. This microstructure complexity is normally reflected in their geophysical response, and makes them more difficult to interpret. Rock physics play an important role to resolve such complexity by integrating different subsurface di...

Bayesian spatial modelling for high dimensional seismic inverse problems

We study the application of Bayesian spatial modelling to seismic tomography, a geophysical, high dimensional, linearized inverse problem that infers the three-dimensional structure of the Earth’s interior.We develop a spatial dependence model of seismic wave velocity variations in the Earth’s mantle based on a Gaussian Matérn field approximation. Using the theory of stochastic partial differen...

The Physics of Rock Failure and Earthquakes

Physical modeling of earthquake generation processes is essential to further our understanding of seismic hazard. However, the scale-dependent nature of earthquake rupture processes is further complicated by the heterogeneous nature of the crust. Despite significant advances in the understanding of earthquake generation processes, and the derivation of underlying physical laws, controversy rema...
