    Abstract: An acoustic transducer array and method of making same. A first metal layer is deposited on a first side of a piezoelectric composite to form a common electrode and a second metal layer is provided over the obverse side. Portions of the second metal layer are removed to create a plurality of individual electrodes. A third metal layer may be deposited onto the plurality of individual electrodes, the third metal layer being thicker than the second metal layer. The individual electrodes extend beyond the piezoelectric composite in the elevation direction to create electrode leads. Metal layers may be provided by lithography, a wireframe or a foil sheet.

    Abstract: Methods and devices for imaging wells using ultrasound is described. The devices include a modular imaging device having a telemetry module and a radial imaging module and/or forward imaging module. The radial imaging module includes a ring shaped phased array ultrasonic transducer array for generating images on the length of a wellbore. Various lens and housing configurations for the radial imaging module are described. The forward imaging module includes an ultrasonic transducer comprising one or more elements and having an adjustable viewpoint for generating images of obstructions found in a wellbore. Advanced imaging modes for a radial imaging module include multiple aperture and spiral wave imaging mode.
