3. Reporting and new ideas for 2013 All our publications, theses, reports and presentations are available on our website: http://www3.imperial.ac.uk/earthscienceandengineering/research/perm/po rescalemodelling http://www3.imperial.ac.uk/earthscienceandengineering/research/perm/po rescalemodelling 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.

4. Personnel and projects Total-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 – 3 rd year PhD student – Multiphase flow on pore-space images. Zaki Al-Nahari – 3 rd year PhD student – Reactive transport. João Paulo Nunes – 1 st year PhD student – Reactive transport and multiphase flow. Chamsi Bouhafs – 1 st year PhD student – Pore-scale modelling of shale gas.

5. (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.
