“Unlock the unseen with advanced acoustic technology”

Spectral Noise Technology is an advanced acoustic logging system designed to detect and analyze fluid movement within and around the wellbore with unmatched precision.

Operating across a wide frequency spectrum from 12 Hz to 60 kHz, it captures the acoustic energy generated by leaks, cross-flows, annular movement, and formation inflow — revealing flow events invisible to conventional tools.

Equipped with ultra-sensitive sensors and high-performance downhole electronics, the system records high-resolution acoustic data continuously, enabling extended diagnostics without intervention.

Whether assessing well integrity, profiling production or injection, or evaluating complex completions, Spectral Noise Technology provides the clarity and confidence required for decision-making in the most demanding well environments.

Enhance well integrity. Optimize production. Unlock subsurface insights.
