4 noise classifications
ramdom or coherant
source generated or ambient
removing taces from seismic data is called
muting
types of muting
refraction mute (at top)/top mute
noise cone mute (cone at bottom)
surgical mute (removal of specific area eg. ground roll)
AGC
automatic gain control
balances amplitudes down a trace (or 'window'-part of a trace)
opposite of the Fourier domain
Amplitude plotted against time
(normal)
Fourier domain
Fourier=Frequency
Amplitude plotted against frequency
why are pre processing algorithms applied?
to prepare data for velocity analysis
supress noise, boost signal
what does 'main processing' acheive?
velocity analysis
