Abstract: A device and method used to image conduits, such as pipes, wellbores and tubulars, with imaging sensors, such as cameras and ultrasound arrays. The speed and location of the device are determined using one or more speed sensor modules. Images are then registered to more precise axial locations along the conduit than are normally possible using wireline encoders or other methods. The conduit may be visualized to proper scale for improved analysis of defects.

Abstract: A downhole imaging tool and method of operating the tool in a wellbore. An imaging sensor array at an end of the tool is rotatable about a longitudinal axis of the tool to image the well by sweeping out a 2D area of the well. Actuators in the tool provide rotation and/or extension of the sensor array to change perspective. An ultrasound phased-array may be used to measure and identify features of the well or objects.

Abstract: A device and method used to increase the resolution when imaging, measuring and inspecting wells, pipes and objects located therein. The device comprises an array of acoustic transducers that both transmit and receive acoustic signals. Scan lines may be overlapped by interlacing transmission and receiving windows thus increasing either the resolution or logging speed drastically compared to conventional approaches. The sequence of the scan lines making up an imaging frame is created by stratifying physically close lines and randomly selecting from within each stratum, preventing interference from neighboring transducers, signals and acoustic artifacts that fundamentally limit logging speed and resolution using conventional methods.

Abstract: An acoustic device and method of manufacturing same. The device may be used to inspect tubulars and parts with high resolution. The acoustic device may include a 2D ultrasonic transducer layer and an ASIC connected to each other by an array of conductive wires. A non-conductive, acoustic damping material is flowed and set around the wires. to form a thick acoustic backing layer. Manufacturing the ultrasonic transducer may involve wire bonding. Electrical Discharge Machining or supporting rigid posts on a substrate. A surface of the backing layer may be machined. plated and diced to create conductive pads to connect the transducer layer to the wires then to the ASIC.

Abstract: A device and method for manipulating a robotic end effector in a well. Actuators manipulate the end effector independently through multiple degrees of freedom to improve the perspective of the end effector. An imaging sensor may be used to image, measure and identify features of a well and objects located therein. The sensor may be an ultrasound transducer, camera or x-ray sensor arranged radially, axial or distributed over a 2D surface. The end effector may be connected to a tool, such as a fishing tool, a welder, a milling tool, or a repair tool.

Abstract: A system, device and method for imaging, measuring and identifying surface features in a tubular, such as a casing, wellbore, or pipe. The device comprises an ultrasound transducer for sonifying an area of the surface of the tubular, with a pulse intercepting axial locations of the sonified area at different times. Reflected signals are processed using their time of flight to interpret the reflected signals as axial locations of features on the surface of the tubular. Multiple sonified areas are partially overlapped in the axial direction to capture features redundantly. Reflections from the multiple areas are combined to remove noise and strengthen reflections from real features. A geometric model of the surface of the tubular is rendered and displayed. Capturing larger areas per frame increases the logging rate and oversampling improves the resolution and signal to noise ratio.

Abstract: An ultrasonic inspection device and method of inspecting parts is disclosed that uses significantly less memory and power with little drop in image quality. The device transmits on a full aperture of ultrasonic elements in a phased array but receives on only a fraction of that aperture. The device may be used downhole, in pipeline inspection or Non-Destructive Testing of manufactured parts.
