ABSTRACT:
A subterranean well packer is inflated by a pumped transfer of rheotropic fluid through a tortuous flow channel into a packer sealing element expansion chamber. The tortuous flow channel and fluid delivery pressure are coordinated with the fluid properties to impose sufficient fluid shear stress for inducement of a substantial phase change in said rheotropic fluid after entry into expansion chamber.
