self-diffusion in isotropic, isothermal media during the diffusion time ∆pl:
<x≈√2(x2f2=2√DΔ [3.29]
Here <x2>ιz2 is root-mean-square displacement. D is diffusivity.
The minimum drop size dmi∏ that is measurable from PGSE data can be
expressed as 15j:

Here δmaχ is the largest magnetic gradient duration can be used in the
measurement (usually δma× = 0.2Δ). Plausible values for Λ are 0.01 ≤λ ≤0.05.
3.3.3. Drop size determination of diluted bitumen emulsion
For diluted bitumen emulsion, the total attenuation for the emulsion can be
written as:
r = M 0iι (g > 0) +M emul (g > 0)+Mwater (g > 0) 1
Moil{g = ^ + Memul{g = Q') + Mwater{g = Q) L ∙ J
Subscripts emul, oil and water correspond to emulsified water, oil and bulk
water phases.
