Summary
Integrity of the Tubing Encased Conductor (TEC) line during installation is critical to the long-term reliability of a DIAL gas lift production optimization system. Silverwell adopts recognized industry best practices in designing TEC clamping and protection strategies.
The DIAL system’s TEC is protected in two ways: by clamping the TEC to the production string and completion components; and by protecting the TEC when there is an upset in the OD of the completion string
Clamps are available in cast or pressed steel configurations with the choice dependent on the specifics of the application. They are typically placed over couplings in the production string - Cross Coupling Protectors.
Custom designs can be specfied to provide protection for tubing crossovers, to secure spliced TEC, or to provide stand off for completion components such as Subsurface Safety Valves and Sliding Sleeves.
