Karstic networks are complex underground assemblies of cavities and tunnels generated by the dissolution of highly soluble rocks. In the frame of virtual scene synthesis, Paris et al. (2019) propose a promising procedural approach to generate karstic features. The goal of this research will be to investigate the possibilities of a recent graph-based approach to stochastically simulate networks that honor geological information and analog data, and thus better assess the associated uncertainties. Integrating this work in an inversion framework using hydrogeological data would be also considered.

Owing to the lack and incompleteness of subsurface data, significant uncertainties exist on the position of structural surfaces (faults and horizons). The present project proposes to develop an innovative way of inverting seismic data to reduce uncertainties on these structures. Instead of using seismic recordings and wave propagation simulations, the method will rely on full waveform inversion (FWI) images and the homogenization operator (e.g., Cupillard & Capdeville, 2018). To be achieved, the development of efficient computing technology for geomodeling will be necessary.

Structural restoration is commonly used to assess the deformation of geological structures and to reconstruct past basin geometries. To bring more physical behavior and better handle large deformations in this process, a reverse-time method based on the Stokes equations was recently proposed by Schuh-Senlis et al. (2020). The goal of the PhD is to investigate the viscous properties of sedimentary materials and fault behavior at the geological time-scale in order to improve this method.
