High-fidelity noise detection tool
Detect leaks and fluid movement in production or injection wells
Identify well leaks and flow events with high-fidelity noise detection
The high-fidelity noise detection (HFND) tool uses broadband hydrophone technology and high-resolution temperature logging to detect wellbore leaks in a wide range of applications, including production, injection, fluid flow, or completion evaluation. The HFND tool captures both short- and full-bandwidth waveforms—sending continuous, real-time spectrogram images to the surface while storing up to 16 GB of high-definition data that can be used for advanced data interpretation.
The leak-detection tool is fully combinable with production logging services and can be conveyed on wireline, DSL™ digital slickline cable, slickline, coiled tubing, or fiber-optic cable in cased-hole wells.
- Casing and tubing leak detection
- Surface and near-wellhead surveillance
- Production logging
- Injection logging
- Annular flow detection
- Multistage fracturing completion evaluation
The HFND tool’s real-time surface readout, combined with its high-capacity memory storage, enables you to ensure well integrity by quickly identifying leak or flow events and guiding your data acquisition program without sacrificing the higher-resolution measurements required for further, more detailed evaluation.
