Reporting and new ideas for 2013All our publications, theses, reports and presentations are available on our website:

http://www3.imperial.ac.uk/earthscienceandengineering/research/perm/porescalemodelling

•Now extending work to study shale gas at the nano-scale.

•Reactive transport and coupling with pore-scale imaging.

•Flow-based network extraction.

•More emphasis on validation and direct pore-space computation.

Personnel and projectsTotal-sponsored project on network extraction. Ali Raeini to continue as a post-doc.

Current group:•Martin Blunt, Professor of Petroleum Engineering – overall supervision.

•Branko Bijeljic, Research Fellow – dispersion and reactive transport in porous media.

•Edo Boek, Senior Lecturer in Chemical Engineering – fundamentals of flow in porous media and wettability.

•Rafi Blumenfeld, Research Fellow – statistical analysis of granular packs. 

•Ali Raeini – 3rd year PhD student – Multiphase flow on pore-space images.

•Zaki Al-Nahari – 3rd year PhD student – Reactive transport.

•João Paulo Nunes – 1st year PhD student – Reactive transport and multiphase flow.

•Chamsi Bouhafs – 1st year PhD student – Pore-scale modelling of shale gas.

(Remaining) challenges• Dealing with data over a range of scales. How to have a

representative image or network.

• Computational efficiency on new platforms. Modelling multi-billion cell problems. Best use of parallel and GPU processing.

• Improved network extraction and modelling. How reliable are our extraction algorithms? Improvement in network shapes, layer stability and pore-filling processes.

• Wettability characterization and pore-scale verification. How do we assign contact angle on a pore-by-pore basis? Can we use pore-scale imaging to provide rigorous validation of our modelling?

• What do we use pore-scale modelling for? Nature of predictability; emphasis on insight into displacement mechanisms.
