Abstract
A gravel pack well tool comprised of a workstring having a gravel pack screen thereon wherein the workstring can be rotated without applying any substantial torque to the screen jacket which forms part of the gravel pack screen. This allows the workstring to be rotated in either direction during installation or removal of the gravel pack screen without damaging the screen jacket. The gravel pack screen is comprised of a fluid-permeable base pipe having a screen jacket rotatably mounted thereon.
