Surface Intervention System (SIS)
Well Integrity. Done Well.
Page last modified
March 14 2023
The first and only system dedicated to near-surface intervention. Delivers a fast, efficient solution onshore or offshore. Multiple operations are performed consecutively at the wellsite. Powerful push, pull, vibrate and rotate capability. Reduced HSE risk, deck space and personnel requirement. Life-of-well support from production optimisation to pre-abandonment. Large cost savings compared to wireline and coiled tubing by reducing personnel, mobilisation costs, and rig up time. Compact system dedicated to shallow intervention work in the tree to tubing hanger range. Fast to deploy using existing Unity wellhead technicians, further reducing headcount, especially when combined with ongoing maintenance
Pro/con
Large cost savings compared to wireline and coiled tubing by reducing personnel, mobilisation costs, and rig up time
Compact system dedicated to shallow intervention work in the tree to tubing hanger range
Fast to deploy using existing Unity wellhead technicians, further reducing headcount, especially when combined with ongoing maintenance
The SIS can be used for far more than traditional intervention work. The system has been deployed to remove stuck safety valves where numerous attempts by traditional methods were unsuccessful
The SIS is limited to shallow intervention work from below the tubing hanger to tree range
Specification
Areas of Application
Plugs - 70,000 lbs push and 40,000 lbs pull | Milling - rotates to mill stuck gates | Frac Sleeve deployment | Inspection access to live well.
OPEX
PEX reduced significantly over traditional methods. A typical wellhead repair requiring plugs to be set can be achieved in 3 shifts by 2 wellhead technicians.
Optimisation
The SIS optimises intervention work by providing a compact footprint, reduction in planned operation time, reduced POB and the system is operated by our wellhead technicians who will also conduct the repair work.
Compatibility
The SIS is compatible as a direct replacement for wireline and coiled tubing operations when conducting shallow intervention work.
Runtime
A typical operation to rig up, run in hole, and set a plug can take as little as 4 hours.
