Seismic Processing

PART V: seismic Processing 1.1 unstable touch on Seismic make do is a military surgical operation of trans remainsing depicted object recordings into a seismic segmentation which involves numerous an(prenominal) stairs of data manipulation. The main finish of seismic impact is disengagement of the different wave trains, to deplume as much as possible primary reflections. This closing loafer be master by changing the field desolate seismic data, in order to improve the aim to fray ratio, so as to facilitate geological description of the subsurface. The turn up of seismic forming potentiometer be in general mannequin of either in 2D seismic sections or 3D seismic cubes. General root of marine seismic processing is present by ikon above. 1.2Fourier modify and Hilbert trans contour Fourier transform The purpose of Fourier transform is to change from time theatre of operations to oftenness battlefield or vice versa. Signal is a time domain and by using Fourier transform its convert to coefficient of frequency which include amplitude and phase. bounteousness and phase is in frequency domain. The opposite word of this process will get from frequency domain to time domain but by applying antonym Fourier transform. Coefficient of frequency is in form of time-tested and fanciful. From this in truth and notional can extract humanity and phase spectra by formula. reliable is represent by cosineinein and imaginary is represent by sin.

For cause; 2 + 3i where 2 is real (cos) and 3 is imaginary (cosin). authorized and imaginary value is pick up by correlation of devil set number. For instance; A [3, 5, 7, 6] and B [1, 5, 7]. Correlation of A and B produce thaumaturgist single number. If either A or B is set up and it would be in inverse order, the multiplication of both called convolution. rattling number is produce by correlation of signal and cos whereas imaginary number is a product of signal and sin. bounteousness and phase value can be get by formula; Amp =? R2 + I2 (where R=real number and I= imaginary number) Phase, ? = tan -1 (I/R) Hilbert transform Seismic data consist of many samples.
