Abstract:
Assessing a rigidity of an interface between a crude oil and a brine includes at least one of: assessing a compression energy for the interface between the crude oil and the brine; assessing a time at which an elastic modulus and a viscous modulus of the interface between the crude oil and the brine are equal; assessing a crumpling behavior or a crumpling ratio of a droplet of the crude oil in the brine; and assessing a coalescence time of droplets of the crude oil in the brine.
