MRST - MATLAB Reservoir Simulation Toolbox

Upscaling
The module contains routines and tutorials for single-phase and two-phase upscaling.

Tutorials

Icon: harmonic upscaling of a SAIGUP model

Harmonic upscaling

The tutorial demonstrates how to perform a harmonic upscaling of permeability on a realistic model with faults and inactive cells using a set of relatively simple calls to 'accumarray'.

Single-phase upscaling

The tutorial  demonstrates how to perform a single-phase upscaling of the absolute permeability for a 2D Cartesian model. The procedure outlined and the routines used are also applicable to 3D models.

Steady-state upscaling

The tutorial demonstrates upscaling of two-phase relative permeability on periodic grids. A single block sampled from SPE10 using is first upscaled by a standard flow-based method to determine the effective
permeability. Then we find relative permeability curves based on steady-state upscaling for the capillary and the viscous limits, as well as based on a set of dynamic simulations.
