distribution and surface relaxivity of water in diluted bitumen p can be obtained, as
discussed in section 3.3.2.
Figure 3.10 T2 distribution of layered water/ oil mixture and water in oil emulsion
Figure 3.11 shows data fitting result of restricted diffusion measurement and
drop size distribution of emulsion from T2 distribution measurement. Surface
relaxivity of water in diluted bitumen p is 0.6 μm∕s based on the data fitting. This
value can be applied for emulsions with same oil/ water system. With surface
relaxivity known, drop size distribution can be calculated only from T2 distribution
of water drops. This is very convenient for the study of emulsion evolution since
CPMG measurement only takes a few minutes to get the raw data.
