Roller Stem Bar
DTI's Stem Bars are used in wireline tool strings to provide extra weight. When used in conjunction with hydraulic or mechanical jars, the closing speed is increased and jarring impact is also magnified.
Roller Stem Bars are used in deviated wells to minimise wireline toolstring friction. They have a similar mass to Solid Stem Bars.
DTI offer alternate sizes, materials and thread connections. Please contact us for more information.
