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 transportable well completion tool is described. The transportable well completion tool comprises a housing with a charge module disposed within the housing. The charge module comprises explosive charges. An initiator module comprising a detonator is coupled to the housing, and a bulkhead member is disposed within the housing between the initiator module and the charge module. A containment cover is secured to the housing to cover the detonator. The transportable well completion tool can be transported with the containment cover in place, and the containment cover can be removed to connect the well completion tool to a tool string for downhole deployment.

Transportable perforation tool

A perforation tool features a container with a longitudinal axis; an initiator module in the container, the initiator module having a firing circuit, an electrical contact at the longitudinal axis, and a detonator housing; and a shaped charge frame in the container, the shaped charge frame having a first end; a second end opposite the first end; a recess for accepting a shaped charge between the first end and the second end, the recess having a wide end and a narrow end, wherein the longitudinal axis is between the wide end and the narrow end; a first electrical contact at the first end, the first electrical contact located at the longitudinal axis; a second electrical contact at the second end, the second electrical contact located at the longitudinal axis; an electrical conductor connecting the first and second contacts; and a ballistic pathway coupling the detonator housing to the narrow end of the recess.
