Injection of water with particles distributed by various features(size,shape,density,surface charge,Z-potential)can highly affect the retention profile(RP)of suspended particles.The main objective of this studyis to investigate non-monotonic retention profiles(NRPs)during the axi-symmetric flow of size-distributedcolloids and accordingly,predict injectivity decline reliably.For this target to be achieved,coreflooding isperformed by water with particles that are distributed by sizes.The results obtained by implementing derivedexact upscaled equations of colloidal transport for multi-component particle population closely match by theexperimental data monitored during the flood provided that the model coefficients are determined from thetuning.Altogether,four tests are conducted from which breakthrough curves(BTCs)and retention profilesin three moments can be observed.The observed close match proves the accurate representation of themathematical model in all tests due to the higher number of degrees of freedom of the experimental dataarray compared to the number of tuned model parameters.
