Abstract:
A wellbore tool for logging wellbore conditions during completion operations, comprising:(a) a completion string composed of a plurality of wellbore tubular; (b) at least one flow control end device carried by said completion string; (c) a plurality of wellbore sensors carried by said completion string proximate said at least one flow control end device including a temperature sensor, a pressure sensor, and a sound sensor; (d) a data processor adapted for receiving sensor data input from said plurality of wellbore sensors and for processing and recording data in a semiconductor memory; (e) a transmitter for transmitting at least a portion of said processed data to a remote location; and (f) wherein during said processing operations a frequency domain transform is applied to sound sensor data in order to calculate a flow rate of fluid passing through said at least one flow control end device.
