The presence of clays in the reservoir plays an important role in EOR applications. The focus of this paper is to characterize the heavy oil rheology behaviour with the presence of kaolinite clay mineral in considering an EOR process using steam injection. The effect of the kaolinite clay concentration has been investigated for viscosity changes in heavy oil and its water-in-oil emulsion formed after steam injection. The clay mineral used in this study is powder kaolinite clay for the Omani heavy-crude oil with 21 ºAPI at 23 ºC. A viscosity was measured to understand the rheology changes by including kaolinite in the original heavy oil and its water-in-oil emulsion formed after steam injection. The experimental results showed that presence of kaolinite clay in the heavy oil results in reducing the viscosity of heavy crude oil and its emulsion at high share rate.
