ABSTRACT:
An apparatus and method for monitoring and characterizing the fluid flow in and around the tubing string in a wellbore, preferably using fiber optic componentry. The apparatus includes a signal sensing demodulator device and a skin friction sensing device positionable within the wellbore. Both devices are in informational communication with each other. The method includes exposing the skin friction sensing device to a fluid flow, transmitting a signal obtained as a result of a movement of the skin friction sensing device from the fluid flow to a signal sensing demodulator device, converting the signal to a numerical value, and computing a parameter or parameters of the fluid flow in the wellbore from the numerical value.
