Patent number: 12205258Abstract: 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.Type: GrantFiled: March 20, 2020Date of Patent: January 21, 2025Assignee: E.V. OFFSHORE LIMITEDInventors: Jonathan Brian Rudd, Christopher Scott, Jonathan Thursby, John Blackwell

Patent number: 10135489Abstract: 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.Type: GrantFiled: March 1, 2017Date of Patent: November 20, 2018Assignee: E.V.
