Abstract
An assembly for minimizing damaging effects of pressure waves on devices in a wellbore. The assembly comprises a dynamic device disposed in the wellbore and generating pressure waves during actuation; a barrier device disposed in the wellbore and presenting an obstacle to the pressure waves generated by the dynamic device; and an occlusion disposed in the wellbore between the dynamic device and the barrier device which reduces the damaging effects of the pressure waves on the barrier device.
