The Welltec® Fluid Imager (WFI)

For measuring water holdup

Introduction

We live and operate in a 4-D world, and so should our data. Visualization capabilities have advanced significantly over the years and with good reason. They provide a means of absorbing information intuitively, breaking down knowledge barriers that were previously limited by words.

Welltec® has been developing own diagnostic sensors since 2005. Today we have a range of logging tools and own suite of well diagnostics tools, including the Welltec® Fluid Imager (WFI).  

Welltec’s outset is coming from the intervention side – our diagnostics tools aim at improving real-time decision making, increasing understanding of the down-hole environment and adding value to our intervention services.

Overview

The Welltec® Fluid Imager (WFI) is a part of the Welltec diagnostic tools family. It measures water holdup and estimates the distribution of permittivity / dielectric constant in a well cross-section. The WFI has full annular coverage of the holdup using a uniformly distributed, multi sensor package. It produces a tomogram, cross-sectional image, of the hold-up fraction at any given cross-section.
The WFI can be deployed independently or combined with the Well Tractor® for deployment within deviated or horizontal wells.
