Fluid flow in the well system creates a rich spectrum of acoustic energy that penetrates the surroundings. This acoustic spectrum is encoded with information about the type of flow, and its location.
But well systems aren’t ‘recording studios’. Sound frequency and intensity vary from barely imperceptible to deafeningly loud. Noisy interference can drown out important signals. And even if the spectrum is captured faithfully, the link between flow and acoustics is so complex that translating it into reliable flow information is often beyond the reach of ordinary systems.
Chorus is no ordinary system.
It delivers incredible resolution and fidelity across the widest spectrum of useful acoustic energy. We use it in our True Flow and True Integrity products to locate flow precisely throughout the entire well system.
