Abstract: A device, system and method to process acoustic images of tubulars and wellbores. Corrections for real-world logging are calculated and stored in correction Look Up Tables (LUT), which are used to display projections or create geometric models of the wellbore or tubular. The user interface allows the user to interact with the projections to update the LUTs to operate on the images. This process helps correct for real-world challenges such as tool eccentricity, tool rotation, tool angle, and speed of sound differences in order to create a more intuitive rendering.

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.
