Summary: Mechanics-based restoration has been being used for the last 10 years and its advantages are valuable: recovery
of the paleo-geometries, deformation chronology, real 3D restoration, deformation mechanisms, oil maturation...
One of the main difficulties of this restoration method is the boundary condition setting. Even if some of them are
quite standard, there is no obvious set. In addition, recent works showed that the classical boundary conditions
used in mechanics-based restoration may have a lack of physical meaning [Lovely et al., 2012]. This seminar will
present a work on the restoration of an extensional analog model obtained in laboratory (data courtesy of C&C
Reservoirs and IFP). It corresponds to a sandbox model deformed using gravity. As the structural uncertainties are
very low and the forward deformation is known, my work consisted in restore this model and try to define and
validate the set of boundary conditions which may be applied on extensional models, in particular presenting a
basement of salt.

On: Friday, 27th of May
Summary: This presentation will give a quick overview of the topics presented during the 2nd Conference on Forward Modelling of Sedimentary Systems in Trondheim (Norway) in April 2016 and during the 7th International Symposium on In-Situ Rock Stress in Tampere (Finland) in May 2016.

A seminar by: Maxence Reberol (LORIA) at ENSG, Nancy.
On: Wednesday, 13th of July.
Summary: This talks will give insights on how to solve partial differential equations with the finite element method on hybrid non-conforming hexahedral-tetrahedral meshes. Some preliminary results obtained with low-order Lagrange finite elements will be presented. The talk will also discuss a method based on a computer graphics approach to measure distances between scalar field defined on distinct meshes. Such method allows to compare performances of different numerical methods on arbitrary meshes.

Stochastic fault simulation described as a constraint statisfaction problem: brainstorming

subsurface geometries. Stochastic approaches sample uncertainties by producing a large
set of equiprobable models. Geological concepts are often used a posteriori to validate and
update the structural models. Instead of validating each realization, we want to define
and integrate constraints during the stochastic simulation. Each constraint may either
represent a geological concept or a field observation. We propose to formalize stochastic
structural modelling as Constraint Satisfaction Problem (CSP). In this paper, we propose
a fault network simulator relying on Constraint Solving methods. Fault geometries honor
given fault observations and size and orientation distributions. Fault network topology
and kinematic are constrained to avoid inconsistent fault branchings and unlikely fault
displacement maps.
