Summary This research includes an investigation of sand production behaviour among different experimental conditions in the macro-scale sample. Experiments were carried out in the specifically designed HPCS and further analysed with a Computer Tomograph. CT scan results for the intact and multi-phase flow experiment specimens are included. During the experimental process, channelling was observed, which requires further investigation. The observed channelling collocates with the numerical model results obtained in the research group.
