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.

Abstract: A device and method used to log images of target objects with ultrasound transducers. The object may be a fluid-carrying tubular, such as a pipeline. The transducers operate as phased arrays, insonifying areas of the target object with a plane wave and then storing the reflected signals. The signals are sampled and summed for each pixel, by considering various paths taken by the wave from transmitting to receiving via that pixel. Refraction and reflection from surfaces are used to determine segments of the paths.
