Fluid Density Inertial

Fluid Density Inertial

Density Measurement

The Fluid Density Inertial (FDI) tool uses the inertial response characteristics of a vibrating tuning fork to determine the density of the wellbore fluid mixture. The FDI tool is a non-radioactive method of determining density that is unaffected by well deviation.


Key Features

  • Production profiling
  • Fluid identification
  • Horizontal and highly deviated wells
  • High flow rates
  • Combinable with other GE Ultrawire™ tools
  • Memory or surface read-out operation
  • Non-radioactive
