Reporting and new ideas for 2014 All our publications, theses, reports and presentations are available on our website: http://www3.imperial.ac.uk/earthscienceandengineering/research/perm/porescalemodelling Giga-scale imaging, simulation and analysis. Reservoir-condition pore-scale imaging of displacement and reaction coupled with direct simulation of these processes. Pore-scale analysis of force balances and rigorous pore-to-network upscaling. More emphasis on validation and direct pore-space computation.

Personnel and projects 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 – Post-doc, multiphase flow on pore-space images (Total project). Zaki Al-Nahari – 3rd year PhD student – Reactive transport. Matthew Andrew – 3rd year PhD student – Pore-scale imaging. João Paulo Nunes – 2nd year PhD student – Reactive transport and multiphase flow. Tarik Saif– 1st year PhD student – Oil shale. Plus interaction with the Qatar programme (Kamal Singh etc).

Challenges from 2013 Dealing with data over a range of scales. How to have a representative image or network: developing multiscale – macro and micro-porosity – networks and a generalized network generation methof. Computational efficiency on new platforms. Continue to improve computational efficiency – billion-cell simulation. Improved network extraction and modelling. How reliable are our extraction algorithms? Use pore-level direct simulation to upscale properties rigorously. Wettability characterization and pore-scale verification. Pore-by-pore contact angle measurement in situ at reservoir conditions. What do we use pore-scale modelling for? Balance of forces, start of upscaling, identification of the generic nature of transport.
