Abstract

An apparatus and method for establishing communication between the interior of a downhole tubular string and a surrounding annulus is disclosed. A downhole perforator includes a perforator housing. An inner profile of the perforator housing has a first section having a first diameter and a second section having a second diameter, where the first diameter and the second diameter are different. The downhole perforator also includes a mandrel slidably disposed within the perforator housing having an upper connector coupled to a linear actuator. The mandrel also includes a slot. A penetrator is disposed within the slot and rotatably coupled to the mandrel. Additionally, a platform is disposed along a wall of the perforator housing and abuts the mandrel. A pivot pin is coupled to the perforator housing and interfaces with the penetrator and rotates the penetrator about the mandrel.
