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.
