Downhole Cables

Downhole Cables

The Prysmian Downhole Cable portfolio is the result of decades of innovation since the company developed the world’s first Tubing Encapsulated Cable (TEC) in 1987.

Today PDT can meet your downhole cabling needs with a range of fit-for-purpose designs that are manufactured to the highest possible standards. The portfolio includes:

TEC (Instrumentation and Power Cables)

This range includes cables designed to carry data or supply power to a wide range of downhole instrumentation, sensors and electrically powered equipment.

PDT’s instrumentation and power cables are manufactured and tested to the highest possible quality standards to make sure they meet the rigours of downhole operation. Cables are available in tube diameters from 1/8” - 5/8” with a range of wall thicknesses and can be manufactured in stainless steel or nickel alloy.

 

TEF (Fibre Optic Cables)

This range includes cables for applications including distributed temperature sensing (DTS), pressure, flow, strain measurement and acoustic sensing. 

PDT’s hydrogen-insensitive fibre optic cables are designed to withstand extreme temperatures (-150 °C to +300 °C) so they can be deployed in the harshest of environments, including those found in arctic or deep subsea applications.

PDT’s fibre optic cables are manufactured to meet the specific needs of an application. Our design team will work with you to specify key parameters including optical fibre type, filler gel, diameter, thickness and tube material to make sure the cable design is optimized for the application and operating environment.

 

Hybrid Cables

This range includes cables where instrument, power and/or fibre optic cables are combined in a single package to eliminate the need for multiple cables or space in the wellhead.

The Prysmian Downhole Technology team can recommend a design to meet an application’s operating parameters and required surface and downhole interfaces. Additionally, we offer a custom design service to cater for situations where a standard design does not meet the specific needs of an application.
