A technique facilitates perforating operations. According to an embodiment, a perforating gun system utilizes a plurality of modular perforating gun sections which are readily assembled to create a perforating gun with a desired number and orientation of shaped charge holders. In some applications, the modular perforating gun sections may be formed of plastic, e.g. injection moldable plastic, to further reduce costs and provide great flexibility with respect to construction of the desired perforating gun.

Perforating gun having modular construction

A perforation tool, and a bulkhead member for a perforation tool, are disclosed. The perforation tool has a loading tube, an initiator module, and a bulkhead member connected between the loading tube and the initiator module. The bulkhead member has a hollow body member with a central transverse plate having a central bore through the transverse plate along a longitudinal axis of the body member and an electrical conductor disposed in the central bore, the electrical conductor having a pin connection at a first end thereof and a box connection at a second end thereof.

Pressure bulkhead

A method of perforating a wellbore is described herein. The method includes lowering a perforating wellbore tool into the wellbore proximate a formation to be perforated, anchoring the perforating wellbore tool by setting an anchoring tool, perforating the formation, creating a low pressure chamber in the perforating wellbore tool, and unsetting the anchoring tool after a time delay.
