Abstract
A system for downhole telemetry employs a series of communications nodes spaced along a tubular body such as a pipe in a wellbore. The nodes allow hybrid wired-and-wireless communication between one or more sensors residing at the level of a subsurface formation and a receiver at the surface. The nodes employ electro-acoustic transducers providing node-to-node communication up a wellbore at high data transmission rates. A method of transmitting data in a wellbore uses a plurality of data transmission nodes situated along a tubular body to deliver an alternating electrical and acoustic transmission of data along the wellbore.
