ABSTRACT:
An isolation device operatively coupled to a wellbore tool is activated upon receiving fluid that a predetermined applied pressure. When the fluid string reaches the predetermined applied pressure, the isolation device undertakes a specified action such as longitudinal movement, rotation, expansion, etc. that actuates or operates the wellbore tool. Premature actuation of the wellbore tool is prevented by applying a resistive force to the isolation device that, alone or in cooperation with another mechanism, arrests movement of the isolation device. This resistive force is generated by applied pressure of the fluid in the work string.
