Where are we heading?

• Major progress in the last year – what we have done• Proposed research for next 1 to 2 years• Funding• Feedback

6

Major progressPore-scale analysis and network extraction

• Micro-CT imaging of various samples provided by sponsors (Shell, Total and Saudi Aramco).

• Work on network extraction and comparison with Statoil results, 3DMA and ANU work (Hu, Anwar and Stefano).

• First results on coordination number and pore size. Still work in progress.

7

Major progressPrediction and pore-scale physics

• Analysis of WAG (Sander).• Physical interpretation of dispersion (Branko).• Prediction of two-phase properties for BG (Sander).• Non-Newtonian flow work extended to yield stress

fluids (Taha).• Analysis of counter-current imbibition in mixed-wet

systems (Hassan).• Ten papers published in last year.

8

Research plans

• Continuation of imaging and network extraction. Validation against test datasets.

• Validation of predictive two- and three-phase flow results and wettability.

• Study of trapping in two and three-phase flow to develop a general three-phase model.

• Continuation of other projects.• Develop collaboration with sponsors and other

groups (Shell, JOGMEC, Saudi Aramco, Total, Statoil, ANU, Stanford).

9

Funding

• As planned have 8 companies and DTI as sponsors• Also 50% funding for a post-doc from EPSRC – to

appoint in early 2005. Will work on pore-scale analysis and network extraction in combination with discrete element simulation of sedimentation

• Continue collaboration with Hiroshi Okabe on multiple-point statistics and lattice Boltzmann simulations (JOGMEC)

• Support 4 PhD students and 2 post-docs
