Downhole Instrumentation Cable: Encapsulated or Bare? When Does it Matter?

Permanent Downhole Gauge Technology For Cemented-In Completions

At GEO PSI we produce some of the worlds best downhole instrumentation sensors. Cementing the pressure sensors in behind the casing is becoming increasingly more common and accounts for a large percentage of our work.

A controversial topic seems to be whether to use an encapsulated cable or a bare cable?

Encapsulated

Advocates of encapsulation point out that the plastic jacket overtop the steel cable provides acts as a bumper and improves survivability of the cable during the deployment of the system.

Bare Cable

Some of our customers prefer that bare cables be installed, citing that they are worried about channelling or bond issues in the cement.
