  • 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
