Summary:
Background noise from the earth can provide a wealth of information about the earth's crust, which can, for example, be used when searching for new oil fields. Researchers from TU Delft have tested this relatively new discovery in a desert in the Middle East. The seismic noise measurements have shown that the theory works in practice.

Background noise from the earth can provide a wealth of information about the earth's crust, which for example can then be used when searching for new oil fields. Researchers from TU Delft have tested this relatively new discovery in a desert in the Middle East. The seismic noise measurements have shown that the theory also works in practice. An article by PhD candidate Deyan Draganov about this research subject has been published in Geophysical Research Letters.

When acoustic noise travels through a medium, such as the earth's crust, it compiles information. Ground microphones, in conjunction with a few simple mathematical processes (cross-correlation), can extract a meaningful signal from the earth's seismic noise. This relatively new method is called 'seismic interferometry'. For researchers, the great advantage of using existing seismic noise is that signals only need to be registered and not produced (with for example vibrating plates, explosives or microwaves).

Geophysicists Kees Wapenaar and Evert Slob of TU Delft, and Roel Snieder of the Colorado School of Mines, have recently generalised the underlying theory of seismic interferometry and demonstrated that the seismic noise can now be applied to a much wider scale of physical applications than was previously thought. Among the applications to which the theory can be applied is the process of searching for new oil and gas fields.
