  • Patent number: 12205258
    Abstract: This invention relates to a method of imaging a downhole region of interest. In particular this invention relates to a method of processing images captured downhole to remove or reduce distortions due to the optical system as a function of the temperature experienced by the optical system in the downhole environment. A method of imaging a downhole region of interest comprises contemporaneously capturing an image of a region of interest and recording a temperature associated with the region of interest; selecting a pre-defined set of distortion data from a plurality of pre-defined sets of distortion data based on the recorded temperature; and applying the selected set of distortion data to the captured image to create an un-distorted image, wherein the pre-defined set of distortion data comprises distortion values associated with a range of field angles at a specified temperature.

  • Patent number: 11215917
    Abstract: Inspection assemblies that include one or more sideview cameras for capturing images of an interior surface of a pipe or conduit include an elongate housing, a sideview camera within the housing and arranged to capture an image of a region within a field of view external to the housing, and a viewport element mounted in the housing and located such that light is transmitted through the viewport element and into said sideview camera, wherein the viewport element has a concave internal surface, closer to the camera, and a convex external surface, further from the camera, and wherein the centre of the radius of curvature of the internal surface is closer to the viewport element than the centre of the radius of curvature of the external surface.

  • Patent number: 11174719
    Abstract: The field of inspection assemblies and in particular to inspection assemblies that include light sources for illuminating a field of view of a camera including an elongate housing having a longitudinal axis, a camera mounted in the housing and arranged to capture an image of a region within a field of view external to the housing, a light source mounted in the housing and arranged to illuminate the field of view, and a window element mounted in the housing, the window element comprising a light transmitting material and being located such that light emitted by the light source passes through the window element before illuminating the field of view. The window element has an internal surface, closer to the light source, and an external surface, further from the light source, and the external surface comprises a concave region.

  • Patent number: 10135489
    Abstract: An inspection apparatus for use in wellbores in the oil and gas industries relates in general to the field of transmission of data between downhole module in a wellbore and a controlling module at the surface. The invention provides a method and apparatus for determining analog filter parameters for an analog front end comprising a plurality of filter stages receiving signals from a telemetry module, by repeating the steps of; receiving a signal of a known frequency and processing said signal by determining the magnitude of the frequency of the received signal until a plurality of signals have been received and processed; calculating an optimum set of filter parameters in dependence upon the measured frequency magnitudes and a predefined set of filter stage frequency responses.
