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.

Claims (15)

1 . 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.
2 . The method of claim 1 , wherein securing the containment cover comprises operating a threaded connection having a number of threads selected based on a discharge capacity of the initiation module.
3 . The method of claim 1 , wherein securing the containment cover comprises covering the initiation module.
4 . The method of claim 1 , wherein the containment cover has a curved end.
5 . The method of claim 1 , wherein installing the detonator comprises positioning the detonator along a central axis of the perforation tool.
6 . A method comprising, removing a containment cover from a perforation tool comprising a housing, a charge module within the housing, an initiation module coupled to the housing, and a bulkhead module within the housing between the charge module and the initiation module, 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; attaching the perforation tool to a tool string; and deploying the tool string into a well.
7 . The method of claim 6 , wherein removing the containment cover comprises operating a threaded connection having a number of threads selected based on a discharge capacity of the initiation module.
8 . The method of claim 6 , wherein, prior to removing the containment cover, the containment cover covers the initiation module.
9 . The method of claim 6 , wherein the containment cover has a curved end.
10 . The method of claim 6 , wherein the initiation module comprises a detonator, and wherein the detonator is disposed along a central axis of the perforation tool.
11 . The method of claim 6 , further comprising causing the perforation tool secured with the containment cover to be transported to a well site, including the well, before removing the containment cover from the perforation tool.
12 . The method of claim 6 , further comprising securing the containment cover to the housing to cover the initiation module before removing the containment cover from the perforation tool.
13 . The method of claim 12 , further comprising: disposing the charge module and a bulkhead member within the housing of the perforation tool; and attaching the initiation module to the housing such that the bulkhead member is between the initiation module and the charge module.
14 . The method of claim 13 , further comprising installing at least one explosive charge in the charge module.
15 . The method of claim 13 , further comprising installing at least a detonator in the initiation module.

Description

This application is a continuation of U.S. patent application Ser. No. 18/724,006, filed Jun. 25, 2024, which is the National Stage Entry of International Application No. PCT/US2023/012466, filed Feb. 7, 2023, which claims benefit of U.S. Provisional Patent Application Ser. No. 63/307,400, filed on Feb. 7, 2022, which are all incorporated herein by reference. BACKGROUND Technical Field This patent application describes an apparatus for use in completing hydrocarbon production wells. Specifically, a perforation tool is described that can be transported in a fully assembled state. BACKGROUND This section is intended to introduce the reader to various aspects of art that may be related to various aspects of the present disclosure, which are described and/or claimed below. This discussion is believed to be helpful in providing the reader with background information to facilitate a better understanding of the various aspects of the present disclosure. Accordingly, it should be understood that these statement are to be read in this light, and not as admissions of prior art. Explosive tools are used in hydrocarbon prospecting to create channels within rock formations to increase flow of fluids from a hydrocarbon-bearing formation into a well for production to the surface. A hole is drilled into the formation, and the tool is lowered into the hole. The tool has explosive charges that create jets of hot, relatively dense gas, which project laterally into the wall of the well, and into the formation, opening pathways for fluid flow from the formation into the well. Such tools, widely known a perforation tools, must be carried to a well site for deployment. Since the tools use explosive charges, transportation of the tools to the well site is heavily regulated. The tools typically have an ignition module and a charge module that are separately transported to the well site to meet transport regulations. The pieces are then assembled at the well site, and the assembly takes some time to accomplish. Perforation tools that can be transported to the well site in a fully assembled state and directly deployed into a well without further assembly (other than attachment to a tool string) are needed. SUMMARY Certain embodiments commensurate in scope with the originally claimed disclosure are summarized below. These embodiments are not intended to limit the scope of the claimed disclosure, but rather these embodiments are intended only to provide a brief summary of possible forms of the disclosure. Indeed, embodiments may encompass a variety of forms that may be similar to or different from the embodiments set forth below. Embodiments described herein provide a well completion tool, comprising a tubular housing; a charge module comprising at least one explosive charge within the housing; an initiation module coupled to the housing and comprising a detonator; a bulkhead module within the housing between the charge module and the initiation module; and a containment cover secured to the housing and covering the detonator. Other embodiments described herein provide a well completion tool, comprising a tubular housing; a charge module comprising at least one explosive charge within the housing; an initiation module coupled to the housing and comprising a detonator; a bulkhead module within the housing between the charge module and the initiation module; and a containment cover secured to an end of the housing and covering the detonator. Other embodiments described herein provide 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 to form a transportable perforation tool; 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.
