Abstract
An electro-acoustic system for downhole telemetry is provided herein. The system employs a series of communications nodes spaced along a string of production tubing within a wellbore. The nodes allow for wireless communication between transceivers residing within the communications nodes and a receiver at the surface. More specifically, the transceivers provide for node-to-node communication up a wellbore at high data transmission rates for data indicative of fluid flow within the production tubing adjacent gas lift valves. A method of monitoring the flow of fluid gas lift valves is also provided herein. The method uses a plurality of data transmission nodes situated along the production tubing which send signals to a receiver at the surface. The signals are then analyzed to determine gas lift valve operation and fluid flow data.
