  • Assemblies and methods for minimizing pressure-wave damage
    Patent number: 8950487
    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.
    Type: Grant

  • Device for the focus and control of dynamic underbalance or dynamic overbalance in a wellbore
    Patent number: 8726996
    Abstract: A downhole tool assembly for use in a wellbore includes a tubular body carrying an explosive which is selectively detonated to create a dynamic underbalance or overbalance effect in the wellbore. The tubular body has opposite ends provided with plug assemblies including plug elements movable between a normally collapsed state and an actuable expanded state. The plug elements are adapted to be actuated to the expanded state between the tubular body and an outer extent of the wellbore before the creation of the dynamic underbalance or overbalance effect to isolate a discrete segment of the wellbore to which the dynamic underbalance or overbalance effect is confined.
