The Surat CCS storage demonstration project requires accurate predictions of the extent of plume movement within the storage complex. This is especially important since the project represents the first-of-a-kind storage containment in the absence of anticlinal trapping. The project builds on the content of a previous ANLEC funded building of a Digital Core Analysis Database and will provide a necessary alternative method for upscaling to the current multi-variate statistical approach being undertaken by eGAMLS.
The project will develop a multiscale workflow which consistently addresses the impact of small-scale geological heterogeneity on the static and dynamic rock properties. The primary research outcome of the program will be to illustrate the importance of incorporating realistic geological structures at multiple scales to offer greater confidence in static and multiphase flow predictions at the individual geocell scale (input to static model).
