Workflow for fast and efficient integration of Petrel-based fault models into coupled hydro-mechanical TOUGH2-MP-FLAC3D simulations of CO2 storage

摘要

We discuss a workflow implemented for coupling arbitrary numerical simulators considering complex geological models with discrete faults. This includes grid conversion of geological model grids generated with the Petrel software package to different simulator input formats within a few minutes for multi-million element models. We introduce the conceptual workflow design and tools required for the workflow realization. In this context, different fault representations can be realized including discrete fault planes supported by a virtual element concept in the multiphase flow simulator or an equivalent porous media approach using the mechanical ubiquitous joint model.
