International audience; This paper is concerned with the Richards equation in a heterogeneous domain, each subdomain of which is homogeneous and represents a rocktype. Our first contribution is to rigorously prove convergence toward a weak solution o

Convergence of nonlinear finite volume schemes for two-phase porous media flow on general meshes

Autor: Léo Agélas, Bernd Flemisch, Martin Schneider, Guillaume Enchéry

In this work we present an abstract finite volume discretization framework for incompressible immiscible two-phase flow through porous media. A priori error estimates are derived that allow us to prove the existence of discrete solutions and to estab

An Efficient Implementation of the Discontinuous Galerkin Method for Multiphase Flows through Heterogeneous Porous Media

Autor: N. Dashtbesh, Benoit Noetinger, Guillaume Enchéry

Publikováno v: ECMOR XVII.

Summary One of the main challenges in immiscible multiphase flows lies in getting an accurate representation of the strong coupling between the unavoidable heterogeneity of the porous medium and instabilities of immiscible multiphase flows appearing

Convergence of nonlinear finite volume schemes for heterogeneous anisotropic diffusion on general meshes

Autor: Léo Agélas, Guillaume Enchéry, Bernd Flemisch, Martin Schneider

Publikováno v: Journal of Computational Physics. 351:80-107

In the present work, we deal with the convergence of cell-centered nonlinear finite volume schemes for anisotropic and heterogeneous diffusion operators. A general framework for the convergence study of finite volume methods is provided and used to e

Sensitivity Analysis and Optimization of Surfactant-Polymer Flooding under Uncertainties

Autor: Sébastirn Da Veiga, R. Barsalou, Samir Touzani, Guillaume Enchéry, Mathieu Feraille, Frédéric Douarche

Publikováno v: Oil & Gas Science and Technology, Vol 69, Iss 4, Pp 603-617 (2014)

Chemical flooding is currently one of the most promising solution to increase the recovery of mature reservoirs. In Surfactant-Polymer (SP) processes, several parameters should be taken into account to estimate the return on investments: concentratio

Numerical Modeling of Thermal EOR: Comprehensive Coupling of an AMR-Based Model of Thermal Fluid Flow and Geomechanics

Autor: Gerard Renard, Guillaume Enchéry, Nicolas Guy

Publikováno v: Oil & Gas Science and Technology – Revue d’IFP Energies nouvelles. 67:1019-1027

Modeling Steam Assisted Gravity Drainage (SAGD) can involve significant CPU (Central Processing Unit) time when both thermal fluid flow and geomechanics are coupled in order to take into account variations of permeability and porosity inside the rese

Publikováno v: SPE Reservoir Evaluation & Engineering. 14:612-620

Summary A new geostatistics-based seismic-inversion method is introduced in this paper for determining reservoir models consistent with base seismic information. The proposed methodology entails two steps, with only the second being examined in this

Local and continuous updating of facies proportions for history-matching

Autor: Guillaume Enchéry, M. Le Ravalec, Elodie Tillier, V. Gervais

Publikováno v: Journal of Petroleum Science and Engineering. 73:194-203

Perturbing facies proportions can provide significant flexibility to assisted history-matching processes since facies strongly impact fluid dynamics. In this paper, we develop a new parameterization technique for varying facies proportions and matchi
