TUNGSTEN STEM SECTION

The LiMARĀ® Tungsten Stem Section is devised to provide the necessary mass required for a wireline toolstring to overcome static or flowing well pressure to enable conveyance in the well.

The Tungsten Stem Section is comprised of a hollow cylinder which is filled with high density tungsten alloy inserts.The inserts are securely retained within the cylinder by the top & bottom subs. Tungsten provides additional mass per equivalent volume compared to standard stem made from conventional steel.
