Coherent Noise In Seismic Data. Seismic noise comprises all of the unwanted recorded energy that contaminates seismic data A part of the seismic energy is considered noise if it does not fit the conceptual model of seismic signal Seismic noise can be random or coherent The identification of seismic noise depends on the.

Coherent noise is more complex and addresses undesirable seismic energy that shows a consistent phase from tracetotrace For example acquisition footprint shallow refractions and multiples Coherent noise is more challenging to overcome than random noise and may result in coherent artifacts on seismic attribute displays that can mask features of.

PDF fileThese noises are characteristically divided into two categories coherent highamplitude noises such as ground roll seismic interferences etc and incoherent high.
Using Data‐Regrouping Methods to Attenuate Shot‐to‐Shot
We have devised a new filtering technique for random and coherent noise attenuation in seismic data by applying empirical mode decomposition (EMD) on constantfrequency slices in the frequencyoffset ( f x) domain and removing the first intrinsic mode function.

PDF fileEffective Coherent Noise Attenuation The most straightforward way to attenuate coherent noise in the RT domain is to apply a highpass (lowcut) filter to the radial traces which directly suppresses coherent noises mapped by the RT transform to subseismic frequencies Applying a lowpass filter to the same radial traces however estimates or.
