Cased-Hole Leak Investigation
Field reference · Southeast Asia
Problem & challenge
A cased-hole leak path and possible tubular or cement integrity issues needed to be located before intervention.
Objective
- Locate the leak, assess corrosion condition and evaluate cement bond around the suspected interval.
Solution
LeakSense leak detection was run with MagScan corrosion logging and RBE radial bond evaluation as an integrated cased-hole investigation.
Result
The leak path and barrier condition were identified, supporting a targeted repair rather than a speculative workover.
