Abstract
An electro-acoustic system for downhole telemetry is provided herein. The system employs a series of communications nodes spaced along a string of casing within a wellbore. The nodes are placed within the annular region surrounding the joints of casing within the well-bore. The nodes allow for wireless communication between transceivers residing within the communications nodes and a topside communications node at the wellhead. More specifically, the transceivers provide for node-to-node communication up a wellbore at high data transmission rates for data indicative of a parameter within an annular region behind the string of casing. A method of evaluating a parameter within an annular region along a cased-hole wellbore is also provided herein. The method uses a plurality of data transmission nodes situated along the casing string which send signals to a receiver at the surface. The signals are then analyzed.
