Monotone Multiscale Finite Volume Method for Flow in Heterogeneous Porous Media

Proceedings, 2014
The MultiScale Finite-Volume (MSFV) method is known to produce non-monotone solutions. The causes of the non-monotone solutions are identified and connected to the local flux across the boundaries of primal coarse cells induced by the basis functions. We propose a monotone MSFV (m-MSFV) method based on a local stencil-fix that guarantees monotonicity ...

Modified Multiscale Finite Volume Method for Two Phase Flow in Porous Media

Volume 7A: Fluids Engineering Systems and Technologies, 2013
Multiscale finite volume (MSFV) method have been developed and applied in various complicated physics. The most important advantage of MSFV method is its computational efficiency. In this paper we present a new set of boundary condition for calculation of basis and correction functions which leads to further reduction in computational time in problems ...

A General Multiscale Finite-Volume Method for Compressible Multiphase Flow in Porous Media

Proceedings, 2008
The Multiscale Finite-Volume (MSFV) method was originally proposed to solve elliptic problems arising from incompressible multiphase flow in highly heterogeneous porous media at reduced computational cost. However, when phases are compressible, especially when the reservoir contains gas, mathematical formulations lead to a parabolic equation to be ...

A Loosely Coupled Hierarchical Fracture Model for the Iterative Multiscale Finite Volume Method

SPE Reservoir Simulation Symposium, 2011
Abstract The hierarchical fracture modeling approach is extended to a loosely coupled strategy in order to enhance its efficiency for highly conductive fractures and to easily integrate it into the iterative Multiscale Finite Volume (i-MSFV) framework.

S-fraction Multiscale Finite-volume Method for Spectrally Accurate Wavefield Simulations

Proceedings, 2015
We have developed a novel approach for discretizing the spatial operator in acoustic and elastic wave propagation simulations. We split the reference fine grid model into multiple subdomains (coarse cells). Their interaction with neighbors is determined by the Neumann-to-Dirichlet (NtD) map.
