Numerical Simulations of Viscoelastic Flows in Fibrous Porous Media

Localized Model Reduction in Porous Media Flow

This paper introduces a new localized approach to construct an efficient reduced order model for fluid flow simulation and optimization in porous media flow. For nonlinear systems, one of the most common methodology used is the proper orthogonal decomposition (POD) combined with discrete empirical interpolation method (DEIM) due to its computational efficiency and good approximation. Whereas re...

Parallel Simulations of Underground Flow in Porous and Fractured Media

In this paper, we present a parallel software for solving linear flow equations in two kinds of subsurface media, a 2D highly heterogeneous porous medium and a 3D fracture network. Parallel computing allows us to solve very large linear systems improving the realism of simulations. For these two applications, we perform a scalability analysis of two parallel solvers : HYPRE and PSPASES. HYPRE i...

HPC Fluid Flow Simulations in Porous Media Geometries

The simulation of ows in porous media on the microscale level requires a high number of unknowns to resolve the geometry of the ssures in-between the sand grains. For the geometric representation of the sand grains we use fracture network-like structures in 2D and sphere packings in 3D. These geometries are created with an in-house scenario generator, based on a modi ed and extended version of ...

Multi-scale high-performance fluid flow: Simulations through porous media

In petroleum production and engineering, the subsurface formation that surrounds the well screen gets, in many cases, deteriorated with time in relation to its hydraulic conductivity. As a consequence, well production declines with time and this limits to a large extent its efficiency. Since well installation is a major production operation that usually requires a large capital, it is always im...
