Validating novel boundary conditions for 3D mechanics-based restoration: an extensional sandbox model example

This paper discusses boundary conditions to be applied for appropriate geomechanical restoration. We use an analog lab model for confronting numerical restoration results and the "ground truth".
This work was performed during the PhD research of Benjamin Chauvin in collaboration with Harvard and Chevron.

Uncertainty management in stratigraphic well correlation and stratigraphic architectures: A training-based method

EdwardsEtAl CAGEO2017

This paper, published in Computers & Geosciences, proposes a new way to sample stratigraphic layering uncertainty by generating possible correlation lines between boreholes.

In this paper published in Mathematical Geosciences, we propose to reconstruct channelized systems with a stochastic inverse simulation that reproduces the reverse migration of the system. Starting from the last channel path, which is often the one that is brought out on seismic data, the method builds step by step possible past trajectories. As abandoned meanders provide clues about the paleo-locations of the river, they are also integrated time step by time step during the reverse simulation process. An application is provided on a satellite image of a fluvial system.

In this new paper published in Marine and Petroleum Geology journal, (i) we propose a geometrical and descriptive approach to stochastically control the channel stacking patterns; (ii) we demonstrate trhrough quantitative metrics that this method makes it possible to control the connectivity between the channels by adjusting the geometry of the migrating areas.

In this new paper published in Geomorphology journal, we (i) present and discuss a set of 21 metrics to characterize both the geometry and the topology of karstic networks, and (ii) to study their properties and their usefulness based on a set of more than 30 actual karsts mapped by speleologists. This data set includes some of the largest explored cave systems in the world and represents a broad range of geological and speleogenetic conditions allowing us to test the proposed metrics, their variability, and their usefulness for the discrimination of different morphologies.
