PhD Proposal 1: Stochastic seismic structural interpretation of geological faults

The goal of this project is to propose a stochastic modeling approach exploiting seismic amplitudes and prior knowledge to generate possible structural models. As compared to classical stochastic structural modeling methods, which all require some interpretation picks or surfaces (see Sect. 4 of Wellmann & Caumon, 2018, and references therein), this method would directly start from the seismic image and do not necessarily impose interpretation picks.

PhD Proposal 2: Geomodel updating and transdimensional flow inverse problems

The first objective of this PhD is to consider more suitable geological parameterizations in transdimensional inversion, such as layer boundaries defined by implicit functions, faults and fractures (Wellmann & Caumon, 2018). The second objective is to assess whether and how to best exploit the local aspect of model updating in transdimensional methods to reduce the computational burden.
