TY - STD AU - A. Fougerat, L. Guérineau PY - 2018// TI - High-quality signal recording down to 0.001 Hz with standard MEMS accelerometers N2 - Recording very low-frequency signal below 1 hertz is a major concern for seismology, in particular passive noise tomography, and is now also considered for some oil and gas applications. The seismic sensors commonly in use for hydrocarbon deposit surveys (geophones and previous generation of MEMS accelerometers) previously had performance limitations in such applications due to their technological design with very low-frequency signal being concealed by instrument noise. Tests on a recent generation of MEMS (Micro Electro-Mechanical System) sensor with an ultra-low noise floor were performed in our lab, and showed outstanding very low-frequency performance in terms of instrument noise and full scale. A teleseism that occurred during our tests was also duly detected.
