in model nanoemulsion/microemulsion systems.

In particular,
“percolation threshold” obviously occurs at water cuts close to 0.2,
phenomena at water cuts close to 0.4 most probable are due to
emergence of “bicontinuous morphology” while “close packed”
phases emerge at water cuts above 0.6.
A complex “nano-resembling” phase behavior may be a fairly
common property of native brine/oil emulsions, as indicated by our
density measurements for mixtures of 12 native (dead) crude oils
with their respective oilfield brines.
