  • Non-metallic compliant sand control screen
    Patent number: 11927082
    Abstract: A sand screen apparatus for use in a downhole operation for hydrocarbon recovery includes a non-metallic material and a mechanical retainer. The non-metallic material has a compressed state and an expanded state, and includes a base polymer, and one or a plurality of smart fillers dispersed with a polymeric matrix of the non-metallic material. The mechanical retainer compresses the non-metallic material in the compressed state. The one or the plurality of smart fillers react with the base polymer in the expanded state after exposure to a wellbore condition.
    Type: Grant
    Filed: February 17, 2020
    Date of Patent: March 12, 2024
    Assignee: SCHLUMBERGER TECHNOLOGY CORPORATION

  • Dynamic contrast on displays using average picture level and histogram analysis
    Patent number: 8125569
    Abstract: Average picture level (APL) of a display and, in examples, histogram information is used to dynamically adjust the display contrast, or “gamma”, using an exponential function. APL can also be used for DC transmission adjustment and black/white stretch.
