Unwelded Chemical Injection Gas Lift Mandrel


Conventional side pocket mandrels (SPM) have inherent challenges related to welding and heat-treatment. These issues are exacerbated when welding nickel-chromium alloys, such as S13%Cr, 25%Cr and Alloy 718, common materials for high cost completions.


Challenges caused by manufacturing processes such as welding and post weld heat treatment require stringent and elaborate QA/QC processes. Despite all efforts, satisfactory repeatability of the manufacturing process is difficult to achive.



Today, SPMs are the only welded loadbearing component in a modern completion string. The elimination of welding brings the SPM to the same structural integrity level as the rest of the machined components in the string.


Petroleum Technology Company’s (PTC) next generation NexLift SI-CI™ SPM enhances the robustness of the completion string and is the best choice for challenging well applications in which superior longevity, strength and enhanced pressure capabilities are required.
