5. 5 Business Meeting Major progress in the last 3 years – what we have done and what we have not done Proposed research for next phase Feedback Any other business

6. 6 Major progress State-of-the-art two-phase mixed-wet code. Successful prediction of experimental data (Per Valvatne). Written three-phase code and performed some prediction of data. Still work in progress, but will finish by October 2003 (Mohammad Piri). Shown field-scale impact of physically-based relative permeabilities (Matt Jackson). Implemented dual mesh method in upscaling (Pascal Audigane).

7. 7 Additional projects Pore-scale modelling of non-Newtonian flow (Xavier Lopez – Schlumberger). Multiple-point statistics for pore-space characterization of carbonates (Hiroshi Okabe – JNOC and Shell). Rate-dependent pore-scale modelling (Mohammed Al-Gharbi – PDO Oman). Dispersion (Branko Bijeljic – EPSRC)

8. 8 What we have not done Developed new empirical models – complexity of three-phase flow at present makes a simple formulation for all cases problematic. BUT did propose a new model at beginning of project. Fully pore-to-reservoir simulator – technical difficulty of coupling own research simulators have made this an unexpectedly difficult task. BUT have looked at large-scale consequences of different models in two and three-phase flow.

9. 9 Research plans Methodology for predicting multiphase flow properties from easily measured data – extensive validation and extension of Per’s present work. Need: good data from participating companies. Multi-point statistical methods for pore-space characterization, particularly for carbonates. Continuation of Hiroshi’s work.

10. 10 Research plans (continued) New pore-scale physics: three-phase flow, rate-dependent effects and non-Newtonian flow. Continuation of Mohammad’s, Mohammed’s and Xavier’s work. Emphasis on three-phase flow. Upscaling – development of a fully multiple- mesh method from pore to reservoir.

11. 11 Funding £20,000 per company per year for three years. Plan to have 8 sponsoring companies. Leverage from DTI – round of proposals in February 2003. If more companies – expand the work scope. If fewer, try direct sponsorship in key areas. Fund 2 post-docs and 2 PhD students.

12. 12 Next meeting Next meeting is planned for Tuesday June 17 th 2003. Combined with general PERM Group Affiliates’ meeting Final report planned for July 2003
