ABSTRACT:
Downhole wellbore tools are actuated by electrically controllable fluids energized by a magnetic field, for example. When energized, the viscosity state of the fluid may be increased by a degree depending on the fluid formulation. Reduction of the controllable fluid viscosity by terminating a magnetic field acting upon the fluid may permit in situ wellbore pressure to actuate a downhole device, such as a wellbore packer.
