    Abstract: A method and instruction memory for processing acoustic images of a tubular to determine the surface of the tubular. The images may be acquired by an acoustic logging tool deployed into a pipe or well. A Machine Learning model is trained to recognize regions of the acoustic images that are internal to the tubular or not, in order to determine surface pixels. The surface pixels may be rendered to create visualizations of the tubular where noise and non-surface features are filtered out automatically.

    Abstract: A system and method used to image cylindrical fluid conduits, such as pipes, wellbores and tubulars, with ultrasound transducers then process the ultrasound images to detect edges and surfaces. The device and method compute monotonic paths through high energy pixels. Functions are used for dropping, extending and selecting an optimal path based on certain criteria, such as path length, path continuity and path energy. The selected path may be used to model and visualize the tubular along with key features, components and defects in 2D and 3D.

    Abstract: A device and method used to inspect wellbores, cased or uncased using cameras and a phased array ultrasound transducer. The optical and ultrasound images are stored on the device and then registered and analyzed together. The present device overcomes the deficiencies currently experience by downhole camera operators, such as poor scale and lack of volumetric perspective.

    Abstract: Various embodiments of a method and apparatus for performing delay calculations are disclosed. In some embodiments, the delay values are used for nondestructive ultrasound imaging. The delay calculations are performed by interpolating the delay values between sampled delay values. In some embodiments, an interpolation polynomial is evaluated for each position in an interpolation region of a transducer array. In some embodiments, the delay values are computed by interpolating the polynomial coefficients. In some embodiments, higher order derivatives of the delay are integrated to compute lower order derivatives, where the derivatives are computed based on the polynomial coefficients. The process is continued until the delay function computes from the first derivatives of the delay function. The delay function is then derived by integrating the first derivative of the delay function.

    Abstract: A bulkhead system for passing conductors between a high-pressure side and a low-pressure side. The bulkhead may be used in harsh environments to pass signals or power to sensors and actuators on one side and to sensitive electronics on the other side. The conductors run through and are bonded at sides to a body, which body is supported in the direction of the pressure differential and not highly supported in other directions.
