The Product
The Nextlift SI™ and SI-CI™
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 achieve.
Application
Interwell’s NexLift SI /SI-CI are the only true single-piece, unwelded Side Pocket Mandrel in the industry. This unique design provides unrivalled structural integrity, removes the last welded completion component from the well along with issues related to installation and retrieval of valves. International Operating Companies are now installing the field proven NexLift SI world wide.
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.Interwell NexLift SI™ 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. The API 19G1 qualification assures full compatibility with the gas lift equipment
designed and manufactured to API standards. Furthermore, all Interwell side pocket mandrels meet and exceed the highest standard in the industry.
Key Benefits
