Pre-Abandonment Surveys
Bring confidence to abandonment
Fli well integrity surveys are ideal for pre-abandonment diagnostics, providing a complete well integrity check to locate the sources of sustained annulus pressure.
From plug to cement to pressure barriers across multiple annuli, Fli integrity surveys deliver the insight you need to reduce risk, avoid delays, and plan abandonment operations with greater confidence.

Get the answerWith rapid data interpretation available on-site or remotely, our specialists - or your own team - can quickly and confidently diagnose wellbore issues, including leaks, cement assurance, injection profiling, and more.
With WellSense, multiple well surveys can be completed quickly and efficiently, making it ideal for high-volume well activities.
Tight on space or access?
Get the answerAs a winchless solution, Fli Dynamic De-spool fibre optic can be hand-carried and deployed at the wellsite by a single engineer – perfect for difficult to access wells, crowded facilities, and offline intervention.
It's simply the best way to deploy optical fibre for distributed sensing in a static well.
Looking for reliable, repeatable well data?
Get the answerThe Fli Dynamic De-spool probe is designed for single use. Its affordability and availability make distributed sensing surveys more accessible and repeatable across all your static wells.
The compact probe is typically disposed of in the rat hole after the job is completed. Alternatively, the dissolvable Fli probe eliminates any risk of the probe being left in the well.
