Our flagship technology is a proprietary spectral noise acquisition and spectral analysis system, the Interrogator.  Interrogator provides a new paradigm of acoustic noise  logging technology with a sensitivity that goes well beyond industry norms.  In a real-time acquisition mode, Interrogator digitizes noise station data at a rate of 96,000 samples per second, a 480% increase in the noise sampling rate of conventional noise tools that record data at 20,000 samples per second. This provides a 10-fold increase in frequency output sensitivity extending across a frequency range from 0.47kHz to 48.0kHz.  

​

Spectra is acquired in a real-time mode at a rate of forty-six, 21.3 millisecond samples per second, to produce 2,816 frequency domain spectra across the entire frequency range of 0.47kHz to 48.0kHz.  Each of these power spectra are spread across 1,024 channels to produce statistically accurate frequency discrimination, frequency intensity and yield enhanced sensitivity to single or multi-phase flow energy responses.  Dynamic Statistical Range Analysis (DSRA), allows us to focus on the frequency spectrum of interest relative to the environment it was captured in, maximizing the response characteristics under a variety of variable downhole conditions.

​

Flexibility was a key driver in designing the way we wanted the Interrogator to function and perform. The system is compatible with conventional noise logging tools, extending their range from a limit of 10.0kHz full-scale to 48.0kHz full-scale with full spectral capability.
