4. Clay wettability and zeta potential characterization
This chapter mainly discusses clay wettability and its effect on rag layer. Zeta
potential measurement is used to characterize wettability change of clay.

Figure 4.1 shows 11.2 hours separation results of brine in diluted bitumen
(N∕B 0.7) emulsions and 200 ppm demulsifier PR5 at different pH, prepared at
30 oC as described in section 3.5.2.
