The Product

The Nextlift SI™ & 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.

NexLift-SI™ and SI-CI™ non-welded side pocket mandrels, offering enhanced structural integrity and longevity for challenging wells

Application

Interwell’s NexLift SI™ & SI-CI™ are the only true single-piece, unwelded Side Pocket Mandrels in the industry. This unique design provides unrivalled structural integrity and 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

Superior structural integrity
Best choice for sour environments
Eliminates the welded components in the completion string
No chamfers and grooves and full-length discriminator slot with rounded edges, improves the success rate of KOT operations
No loose parts that can be dropped in hole (hinged keeper plates)
