Pore scale modelling
The Imperial College Consortium on pore scale modelling develops network models as practical reservoir description and simulation tools to study a variety of two- and three-phase displacement processes.
There are two main projects. The first will use pore-scale models based on a realistic description of the pore space and a detailed analysis of displacement mechanisms to predict multiphase flow properties based on available data from thin section analysis, capillary pressure and wettability indices.
These models will then be used to assess the variability in relative permeability and capillary pressure. The pore scale model will predict the spatial distribution of relative permeabilities in a reservoir model, in a manner similar to geostical methods for assigning porosity and absolute permeability.
In the second project, a multi-scale simulation methodology is being developed that will couple network models at the pore scale directly with conventional grid-based simulation at larger scales. The method will overcome the inaccuracies and uncertainties inherent in conventional upscaling techniques.
Experiments are performed on core samples, micro CT images are obtained from these samples (the grains are red while the pore spaces are in purple), networks are then extracted from the micro CT images by using the network extraction code.
Funding from a consortium of companies is requested at a level of £30,000 per year.
The Consortium at present has support from the UK Department of Trade and Industry and the following companies:
- Access to all software developed.
- Six-monthly project meetings.
