Some interesting seismic noises

SEG Technical Program Expanded Abstracts 1984, 1984
ABSTRACT This paper suggests that the identification of seismic noise increases our ability to evaluate deeper drilling targets. Seismic noise, as illustrated in basic, unstacked data, is shown to contain clues which the seismic processor may use to improve the resolution of the seismic section.

Scattered Seismic Noise

Exploration Geophysics, 1988
Wave test seismograms from an Aramco concession area show crisscross patterns of noise which mask the reflections. The criss-cross pattern that follows the arrival of the Rayleigh wave is sometimes very strong and entirely masks any reflections that may be present. This zone is very often referred to as the 'noise cone'.

Biological noise on seismic data

SEG Technical Program Expanded Abstracts 1993, 1993
ABSTRACT The geophysicist increases the resolution of the subsurface by using closely-spaced detectors. Ambient noise becomes more important with the short recording arrays so as to increase the importance of biological noise.

Seismic interference noise attenuation

SEG Technical Program Expanded Abstracts 2004, 2004
Summary Attenuation of seismic interference noise that overpowers seismic reflections can be achieved by making use of wellknown f-x prediction filters and the non-predictability of interfering noise from shot to shot.

Information from Seismic Noise

Science, 2005
Contrary to intuition, noise can contain useful information. In his Perspective, [Weaver][1] highlights the report by [ Shapiro et al .][2], who show that noisy seismic wave fields can be used to extract information about the Earth's crust. Despite their random appearance, the wave fields retain a residual coherence, which distributes their energy in ...

Seismic interferometry—turning noise into signal

The Leading Edge, 2006
Turning noise into useful data—every geophysicist's dream? And now it seems possible. The field of seismic interferometry has at its foundation a shift in the way we think about the parts of the signal that are currently filtered out of most analyses—complicated seismic codas (the multiply scattered parts of seismic waveforms) and background noise ...

Short-period seismic noise

Bulletin of the Seismological Society of America, 1967
abstract This report consists of a summary of the studies conducted on the subject of short-period (6.0-0.3 sec period) noise over a period of approximately three years. Information from deep-hole and surface arrays was used in an attempt to determine the types of waves of which the noise is composed.
