Abstract:
A perforating device has an elongated tubular housing and a loading device supporting a plurality of shaped charges. The loading device and the shaped charges are located inside the housing. A volume reduction device is adapted to fit within the loading device and to conform to the profile of the shaped charges thereby filling open volume in the housing.
