Completed PhD and MSc:

Upscaling

Software prototype: Generates input data to simulation/upscaling software SSL2D from raster images of fractured sections:

Image Numerical flow simulation on SSL2D successfully tested on realcase sections

Single phase flow simulated with periodic boundary conditions

Effective permeability full tensor represents the whole (homogenized) fracturedflow unit.

Postdoc: - Numerical aspects of transient two-phase flow simulation - Software code for transient two-phase flow simulation including full tensor permeabilities on unstructured grids
