Fluid Density Inertial (FDI)
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 which is unaffected by well deviation. The sensor is a stainless steel tuning fork which is vibrated near its natural frequency of operation by a piezoceramic stack and control electronics in the upper section of the tool. The frequency and amplitude of vibration are used to determine the actual density of the fluid surrounding the fork. Optimum quantitative results are achieved in liquid-liquid mixtures or in pure gas.
