Quick disconnect system for use with downhole tools

An electric submersible pump (“ESP”) comprising:

• a first subsystem;
• a second subsystem;
• and
• a quick disconnect system coupling the first subsystem to the second subsystem such that the first subsystem is in fluid communication with the second subsystem, the quick disconnect system comprising:
• a head coupled to the first subsystem and comprising a receptacle and a channel having a locking portion;
• a base coupled to the second subsystem and comprising:
• a sealing portion positioned within the receptacle of the head;
• a pin extending radially from the sealing portion of the base positioned within the channel of the head such that relative rotation of the head and the base positions the pin within the locking portion of the channel, wherein;
• a locking nut positioned on a threaded portion of the base, such that, when the pin is positioned within the locking portion of the channel, tightening the locking nut compresses the pin against a wall of the channel to prevent separation of the base and the head;
• and
• a seal positioned between the receptacle and the sealing portion of the base.

A method of assembling an ESP, the method comprising:

• coupling a base of a quick disconnect system to a first subsystem of the ESP;
• coupling a head of the quick disconnect system to a second subsystem of the ESP;
• positioning a sealing portion of the base within a receptacle of the head such that a pin of the base is positioned within a channel of the head;
• rotating the base relative to the head such that the pin is positioned within a locking portion of the channel;
• and
• tightening a locking nut of the base to compresses the pin against a wall of the channel to prevent separation of the base and the head.
