  • Method and system to quantify damage to gravel pack screens
    Patent number: 9624766
    Abstract: A system and method to quantify damage to a gravel pack screen include the use of a flux leakage tool to record electromagnetic field measurements at a plurality of points on the gravel pack screen. The system also includes a processor to obtain the electromagnetic field measurements recorded at the plurality of points and to suppress a baseline signal associated with electromagnetic field measurements resulting from perforations of the gravel pack screen to isolate and quantify flux leakage resulting from the damage to the gravel pack screen from flux leakage resulting from the perforations.
    Type: Grant
    Filed: June 9, 2014
    Date of Patent: April 18, 2017
    Assignee: BAKER HUGHES INCORPORATED

  • Alignment of downhole strings
    Patent number: 9200487
    Abstract: A downhole system includes a downhole string insertable within a subterranean wellbore and a roller assembly coupled with the string. The roller assembly includes rollers mounted on lateral sides of the downhole string for reducing the resistance of deploying the string within the wellbore. The string is rotatable about its axis with respect to the roller assembly; bearing surfaces, or low torque surfaces, are included in the roller assembly to further reduce rotational friction so the string precisely positions itself to a designated orientation.
