Summary
DIAL in-well units are connected to surface via a Tubing Encased Conductor (TEC). This provides power and communication.
The DIAL Cablehead Termination allows electrical communication between the TEC and the DIAL Units while offering protection from the harsh downhole environment.
Internally, the termination provides a pluggable electrical interface that can be made up on the rig floor during completion operations or off-line ahead of time. Externally, it uses industry standard gas tight cone-and-thread as well as ferrule-style seals to protect the internals from well fluids. After makeup, these seals are fully pressure testable before being installed in the well.
Integral to the DIAL Unit there is also a redundant GTMS (Glass to Metal Seal). This isolates the unit’s electronics from the inside of the Cablehead Termination in case there is eventual gas ingress.
Applications
-
All DIAL installations
Supplied with all concentric, slimline and sensing DIAL units.
-
Assuring reliability
Made up and integrity tested prior to and during installation.
-
Splice kits
Available for planned splices or well-site repair of damaged TEC.
Features
- Preassembled with pluggable electrical connectors and no crimps
- Easily reconnectable at the wellsite with no additional equipment cost
- Industry standard and proven metal-to-metal seals
