E-Coil Cable Head

The Global Dynamics’s E-coil Cable Head is a patented tool that is designed for coiled tubing e-coil operations.  GDI’s E-Coil Cable Head provides a means by which to connect wireline inside of coiled tubing and the coiled tubing itself.  It is used in production logging, downhole camera applications, and with perforation guns, as well as a variety of smart coil applications.

The tool creates a termination point for the wireline and gives an electrical connection to the tools that are being run in the well.  Our E-Coil Cable Head is designed with a shock-mounted dual activated disconnect, which serves as an emergency release in case the tools become stuck in the well.  Dual Flapper Check Valves in the tool prevent any backflow up the coiled tubing.  Tool sizes range from 1.688” (42.9mm) to 2.875” (73mm) OD in a wide variety of configurations.The Lower Pack-off creates a chamber which allows the wireline to be terminated and connected to a standard electrical connection that is not affected by wellbore or pumped fluid.  The Cable Head can be run in temperatures up to 302°F (150°C) and under pressure up to 10,000 PSI (70MPa).
