Simulating CO 2 Sequestration

1. Simulating CO2 Sequestration Hans-Joachim Bungartz, Tobias Weinzierl, Aron Ahmadia KAUST-TUM Special Partnership http://www.mac.tum.de The goal of this project is to design and investigate novel approaches to modeling and simulation of CO2 sequestration processes in the context of enhanced oil recovery. The project involves both fine-grain simulations - with all related aspects from multi-phase schemes via numerical algorithms to high-performance computing issues - and homogenization approaches to efficiently capture the fine-grain effects on the macro-scale. This work requires experts in flow physics, mathematical modeling, numerical algorithms, optimization and inverse problems, and high-performance to work collaboratively.

The high capability of the KAUST Shaheen supercomputer will allow for even higher fidelity physical models for CO2 sequestration, long-term analysis of flow behavior enabled by load-balanced dynamic adaptivity over regions of interest.
