Detonation module

A method of activating a perforation tool, comprising:

• inserting a first end of a perforation unit into a second end of a detonation module, thereby electrically connecting the perforation unit to the detonation module via an electrical contact and an electrically conductive member, wherein the electrically conductive member is configured to directly couple to the first end of the perforation unit and form an electrical connection between the electrical contact and the first end of the perforation unit;
• electrically connecting the electrical contact with a switching circuit in the detonation module, wherein the electrical contact is disposed between a detonator and the electrically conductive member;
• electrically connecting the switching circuit to the detonator in the detonation module;
• and
• causing an electrical impulse to be sent from the switching circuit to the detonator.

A perforation tool, comprising:

• a perforation unit configured to house one or more shaped charges;
• and
• a detonation module coupled to the perforation unit, the detonation module comprising:
• an end configured to receive and couple to the perforation unit;
• a detonator;
• a switch circuit electrically coupled to the detonator;
• an electrical contact electrically coupled to the switch circuit;
• and
• an electrically conductive member configured to directly couple to a portion of the perforation unit and form an electrical connection between the electrical contact and the portion of the perforation unit, wherein the electrical contact is disposed between the detonator and the electrically conductive member.
