Spectraseis collaborates closely with the Swiss Federal Institute of Technology (ETH Zurich) and the Swiss Commission for Technology and Innovation (CTI) on several multi-year research programs in addition to its own internal research.

The scope of these programs includes:

▪ LF seismic data acquisition

▪ Numerical modeling of wave propagation in porous media

▪ Rock attenuation laboratory measurements of low frequency seismic signals in fluid-bearing rocks at in situ reservoir conditions

▪ LF data processing and interpretation methods

▪ Fundamental theories in LF hydrocarbon microtremors

▪ Wavefield decomposition studies to determine sources and modes of measured wavefield.

▪ Specialized studies and experiments to better understand the nature of LF measurements, such as borehole and underground gas storage studies.
Results from this research are rapidly advancing our understanding of low frequency phenomena and have generated intense industry interest, as well as a growing portfolio of publications and patent filings.

The movie shows a 3D Rayleigh wave field within the model space. There is a single rectangular reservoir placed at 1km depth which causes clear distortion in the wavefield. The ‘turning wheels’ effect comes from partial display of Rayleigh waves in 3D.
