Abstract
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.

A method of using a perforation tool, comprising:
- disposing a charge module and a bulkhead member within a housing of the perforation tool;
- attaching an initiation module to the housing such that the bulkhead member is between the initiation module and the charge module;
- installing at least one explosive charge in the charge module;
- installing a detonator in the initiation module;
- securing a containment cover to the housing to cover the detonator and form a transportable perforation tool, the containment cover comprising a window for detecting discharge of the initiation module before removing the containment cover, the window comprising a light-transmissive material;
- causing the transportable perforation tool to be transported to a well site;
- at the well site, removing the containment cover from the perforation tool;
- attaching the perforation tool to a tool string;
- and
- deploying the tool string into a well.
