Reporting and new ideas for 2015All our publications, theses, reports and presentations are available on our website: http://www3.imperial.ac.uk/earthscienceandengineering/research/perm/porescalemodelling

•Direct observation of pore-scale displacement and assignment of pore-by-pore wettability.

•Emphasis on reactive transport imaging and modelling.

•Combining direct simulation methods into upscaled generalized network models.

Personnel and projectsCurrent 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).•Bagus Muljadi – Post-doc, Non-Darcy flow and upscaling (EPSRC project).•Zaki Al-Nahari – final year PhD student – Reactive transport.•Matthew Andrew – graduating PhD student – Pore-scale imaging.•João Paulo Nunes – 3rd year PhD student – Reactive transport and multiphase flow.•Tarik Saif– 2nd year PhD student – Oil shale.•Hasan Nourdeen – 1st year PhD student – Multiphase upscaling (Aramco)•Ahmed Al-Ratrout – 1st year PhD student – Wettabilty annd modelling (ADCO)

Plus interaction with the Qatar programme (Kamal Singh, Hannah Menke, Yousef Al-Khalaifi etc).

Challenges for 2015• More accurate representation of complex media. Incorporating

micro-porosity, or other features over a range of scales. Combining flow, transport and chemical reaction.

• Generalized pore-scale modelling an upscaling. View a network model as a generic upscaling tool, using direct simulation or experiment to assign effective properties.

• Integration with pore-scale experiments. Use imaging not simply to define the pore space, but assign contact angle, elucidate displacement processes and allow a pore-by-pore validation of models.
