SPECTRAL NOISE LOGGING

EDSN COMBO. MULTI-STRING CORROSION & SPECTRAL NOISE COMBO

EDSN combo represents the complete well integrity toolbox which enables operators investigate and locate integrity failures before they escalate. Designed to deal with the complex well integrity issues, EDSN combo comprises electromagnetic defectoscope, two hydrophones for spectral noise logging, flowmeter and other conventional sensors necessary to conduct full well integrity survey. The tool can also be run in spectral noise logging mode only by removing the electromagnetic defectoscope from the toolstring assembly. Superior to memory tools, the surface readout technology provides full control and allows saving operational time. In a single run, the tool provides corrosion evaluation of three concentric pipes and allows to detect and confirm the well integrity failures in a real-time. The combo tool is compatible with all logging systems and is run on a mono-conductor cable.
