X-treme SJI™
an innovative, efficient and safer method for decommissioning projects
X-treme SJI™ (Slot, Jet, Isolate) is a patented multi-purpose mechanical slotting system designed to improve the overall efficiency of decommissioning projects. The X-treme SJI™ system optimises the conventional methods for the P&A of wells.
To improve efficiencies, reduce costs and exposure in the Plug and Abandonment (P&A) market the X-treme SJI™ tool has been developed to overcome the existing challenges with the incumbent methods.
The X-treme SJI™ is designed to run in the well to the desired depth and initially slot the casing whilst jetting the slots at the same time cleaning up the outside of the casing. Once the casing has been suitably slotted and cleaned the tool can then fully wash the casing and place the isolation material both outside and inside the casing to create the complete P&A barrier.
