  • Sand control screen
    Patent number: 10294760
    Abstract: The present disclosure relates to apparatus and methods for isolating a tool, such as a sand control screen, from axial and/or torsional loads applied to a tubular string. A sand screen assembly includes a sand control screen, a fixed-end coupling, and a free-end coupling. A first end of the sand control screen is coupled to the fixed-end coupling by a secure connection, and a second end of the sand control screen is coupled to the free-end coupling so the second end of the sand control screen is free to rotate or move axially relative to the free-end coupling.
