TUNGSTEN STEM SECTION
The LiMAR® 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.
TOOL APPLICATIONS:
- Commonly used in applications where additional mass is required without having to increase the overall length of the toolstring
- Ideal for use in flowing surveys where additional mass is required to overcome the generated upward force of a flowing well
DESIGN FEATURES & BENEFITS:
- Positive insert securing feature to prevent internal movement
- Available in industry standard toolstring sizes
- Connection options to suit customer requirements
- Selected components QPQ treated
- Hexagonal flats for safe make-up & break-out
