Cased-Hole Logging

Capacitance Temperature Flow


Capacitance Temperature Flow

Short combination tool

By combining multiple sensors, the overall tool length is reduced compared to a standard length PLT string. The Capacitance Temperature Flow (CTF) combines three sensors together – capacitance water hold up, temperature and flowmeter – with a single electronics section.

 

Key Features

  • 3 sensor measurement in a single tool
  • Quantitative downhole fluid hold-up measurement
  • Well-fluid velocity and direction
  • Leak and cross-flow detection
  • Temperature of the surrounding borehole fluid
  • High resolution and fast response
  • Combinable with other GE Ultrawire™ tools
  • Memory or surface read-out operation
