Product Description

Roxar supplies a wide array of Tubing Encased Conductors (TEC) specifically engineered to meet the harsh environmental challenges associated with the downhole environment. The cable serves as a medium for power and interfaces two-way communication between the DHNC (Downhole Network Controller) and the well’s downhole instruments. Roxar offers a selection of single conductor cables, dual conductor cables, bumper cables, and flatpacks. Our engineers collaborate with customers to optimize component selection, such as tubing alloy characteristics, wall thickness, and encapsulation materials to meet specific well parameters.

Features

  • The welded stainless steel and nickel alloy tubing provides superior conductor protection from physical and chemical impact.
  • The metallurgy and wall thickness of the protective tubing is determined based on well conditions such as pressure, temperature, and chemical resistance to the well media.
  • The completed tubing is cased in encapsulation material selected for resistivity to temperature and well media to provide additional protection to the tubing encased cable.
  • Roxar frequently designs, produces, and delivers combination flatpacks to incorporate hydraulic lines as required to provide complete solutions to optimize installation time, resulting in less spooler units on deck, better safety, and efficiency.
  • An additional standard galvanized steel bumper can be added to flatpack configurations to further increase crush resistance.
  • As a part of our quality assurance process, each cable is tested electrically before transportation to the well site.
