Numerical Simulations of Viscoelastic Flows in Fibrous Porous Media

Markov Random Field Models for High-Dimensional Parameters in Simulations of Fluid Flow in Porous Media

We give an approach for using flow information from a system of wells to characterize hydrologic properties of an aquifer. In particular, we consider experiments where an impulse of tracer fluid is injected along with the water at the input wells and its concentration is recorded over time at the uptake wells. We focus on characterizing the spatially varying permeability field which is a key at...

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...
