Abstract
An example method includes providing source light to an optical fiber deployed in a downhole environment, receiving backscattered light from the optical fiber, and producing one or more optical interferometry signals from the backscattered light. The method also includes converting each of the one or more optical interferometry signals to an electrical signal and digitizing each electrical signal to obtain one or more digitized electrical signals. The method also includes deriving acoustic activity values as a function of time and position from the one or more digitized electrical signal. The method also includes applying at least some of the acoustic activity values to a flow prediction model to obtain a predicted fluid flow as a function of time, wherein the flow prediction model includes a proppant compensation value or factor. The method also includes storing or displaying the predicted fluid flow.
