four emulsion samples described in Table 3.2. The waiting time t_w is 0.6 s. The

imaging pulse field gradient is 0.8 G∕cm. In Figure 3.16, x axis A is signal

amplitude of the sample, y axis position is the position measured from the middle
of the sample. It ranges from -2 cm to 2 cm; the total length is about 4 cm, which is

equal to the height of the sample.

The Ti value of water is greater than diluted bitumen, so the attenuation of
water is smaller than diluted bitumen based on the Eq. [3.33]. Thereby in the
profile results, the signal amplitude of water is smaller than that of oil. Based on
the 7^ι difference, the signal amplitudes of different phases in the emulsion
become distinguishable.
