  • Downhole perforator assembly and method for use of same
    Patent number: 7467661
    Abstract: A downhole perforator assembly (10) for establishing communication between the interior of a tubular string (18) and a surrounding annulus (24) includes a downhole power unit (100) having a power unit housing (150) and a moveable shaft (130) and a downhole perforator (260) having a perforator housing (262), a mandrel (278) slidably positioned within the perforator housing (262) and a penetrator (288) radially outwardly extendable from the perforator housing (262). The power unit housing (150) is operably associated with the perforator housing (262) and the moveable shaft (130) operably associated with the mandrel (278) such that when the downhole power unit (100) is activated and the moveable shaft (130) is longitudinally shifted relative to the power unit housing (150), the mandrel (278) is longitudinally shifted relative to the perforator housing (262) and at least a portion of the penetrator (288) is extended radially outwardly from the perforator housing (262).
