Abstract: 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.
