Fourth Workshop of the strategic action DIP, October 10th and 11th 2016
Modélisation et simulation Avancée de phénomènes de propagation d’ondes dans des milieux GéophysIQUEs 3D Mes thèmes de recherche concernent la modélisation et la simulation numérique de la propagation d’ondes géophysiques. Ils ont pour objectif d’améliorer la précision des méthodes d’imagerie sismique (Reverse Time Migration, Full Waveform Inversion) tout en diminuant…

hp-Adaptive Simulation and Inversion of the Magnetotelluric Measurements The magnetotelluric (MT) method is a passive exploration technique that aims at estimating the resistivity distribution of the Earth’s subsurface, and therefore at providing an image of it. This process is divided into two different steps. The first one consists in recording…
“Simulation of elastic wave propagation in time harmonic domain using discontinuous Galerkin methods” The scientific context of this thesis is seismic imaging which aims at recovering the structure of the earth. As the drilling is expensive, the petroleum industry is interested by methods able to reconstruct images of the…
Finite element approximation of Helmholtz problems with application to seismic wave propagation. The main objective of this work is the design of an efficient numerical strategy to solve the Helmholtz equation in highly heterogeneous media. We propose a methodology based on coarse meshes and high order polynomials together with a…

Wave propagation in a domain including small heterogeneities: asymptotic modeling and nmerics In this thesis, we focus our attention on the modeling of heterogeneities which are smaller than the wavelength. The document is decomposed into two parts : a theoretical one and a numerical one. In the first part, we…
