The LiMAR Multi Roller Tungsten Stem provides the necessary mass and reduced friction required for a wireline toolstring to overcome deviation and the upward-acting effects of well pressure.
This is achieved by integrating the LiMAR® Multi Roller Wheel Subs above & below a tungsten-fifilled housing section. Tungsten provides additional mass per equivalent volume compared to standard stem made from conventional steel. Strategically placed along the length of the wireline toolstring, the mass and drag reducing properties of the LiMAR® Multi Roller Tungsten Stem also serves to enhance bi-directional impact forces during jarring operations.
