Abstract

The precipitation and deposition of asphaltenes in porous media and their interactions with rock and fluids represent complex phenomena which need to be investigated under static and dynamic flowing conditions [1]-[4]. Dynamic method will be used for in-situ asphaltene precipitation in the porous media. In this study, experimental results will be investigated the effect of asphaltene precipitation and deposition on oil reservoir parameters and performance including porosity reduction, absolute permeability reduction, relative permeability changes, capillary pressure changes and wettability alteration during WAG process.
