NexLift RO-CI Chemical Injection Gas Lift Mandrel

NexLift RO
Next Generation Side Pocket Mandrel
NexLift RO-CI
Next Generation Chemical Injection Side Pocket Mandrel

PTC’s NexLift RO-CITM is an innovative Side Pocket Mandrel with only two circumferential welds, manufactured using proprietary robotic TIG welding eliminating many of the shortcomings in the conventional manufacturing processes. This enhances the quality and reduces the risk of completion failure along with issues related to intervention operations. International Operating Companies are now installing the field proven NexLift RO-CITM worldwide.



Current manufacturing processes for conventional side pocket mandrels (SPM) have inherent challenges related to welding and heat-treatment.


Welding and post weld heat treatment rely on extensive human intervention, requiring stringent and elaborate QA/QC processes exceeding the current standards. As such,
satisfactory repeatability of the manufacturing process is difficult to achieve.



By utilizing modern manufacturing technologies and an innovative mandrel design, PTC has managed to minimize the number of orbital welds, and enhanced the control of post weld heat treatment, robotic welding ensures the repeatability of the manufacturing process.


Petroleum Technology Company’s NexLift RO-CI™ SPM with significantly enhanced design, modern manufacturing process and rigorous QA/QC provide the best repeatable quality and therefore the most robust welded side pocket mandrel available in the market place today. PTC’s strict manufacturing process, that exceeds API's 19G1 requirements, assures unsurpassed quality and full compatibility with the chemical injection valves designed and manufactured in accordance to the API 19G2 standard
