Title: Imbibition assisted oil recovery
Author: Pashayev, Orkhan H.
Abstract: Imbibition describes the rate of mass transfer between the rock and the fractures . Therefore , understanding the imbibition process and the key parameters that control the imbibition process is crucial . Capillary imbibition experiments usually take a long time , especially when we need to vary some parameters to investigate their effects . Therefore , this research presented the numerical studies with the matrix block surrounded by the wetting phase for better understanding the characteristic of spontaneous imbibition , and also evaluated dimensionless time for validating the scheme of upscaling laboratory imbibition experiments to field dimensions . Numerous parametric studies have been performed within the scope of this research . The results were analyzed in detail to investigate oil recovery during spontaneous imbibition with different types of boundary conditions . The results of these studies have been upscaled to the field dimensions . The validity of the new definition of characteristic length used in the modified scaling group has been evaluated . The new scaling group used to correlate simulation results has been compared to the early upscaling technique . The research revealed the individual effects of various parameters on imbibition oil recovery . Also , the study showed that the characteristic length and the new scaling technique significantly improved upscaling correlations .
