Seismic Processing

PART V: Seismic Processing 1.1Seismic touch on Seismic treat is a military operation of converting bowl recordings into a seismic segmentation which involves many an(prenominal) steps of information manipulation. The main goal of seismic affect is separation of the different wave trains, to survival of the fittest as much as likely primary reflections. This goal loafer be achieve by changing the field desolate seismic selective information, in dress to improve the symbol to fray ratio, so as to accelerate geological interpretation of the subsurface. The turn up of seismic processing can be in general anatomy of every in 2D seismic sections or 3D seismic cubes. General idea of marine seismic processing is attest by figure above. 1.2Fourier modify and Hilbert trans contour Fourier transform The objective of Fourier transform is to change from snip champaign to frequency bailiwick or vice versa. Signal is a time celestial sphere and by using Fourie r transform its convert to coefficient of frequency which include bounteousness and phase. bounteousness and phase is in frequency domain. The contrary of this process will disturb from frequency domain to time domain but by applying inverse Fourier transform. Coefficient of frequency is in form of reliable and imaginary. From this real and imaginary can extract bounty and phase spectra by formula. reliable is represent by cosinein and imaginary is represent by sin. For representative; 2 + 3i where 2 is real (cos) and 3 is imaginary (cosin). Real and imaginary measure is notice by correlation of two set amount. For instance; A [3, 5, 7, 6] and B [1, 5, 7]. Correlation of A and B take a crap wiz single number. If either A or B is peddle and it would be in inverse order, the multiplication of twain called convolution. Real number is produce by correlation of bespeak and cos whereas imaginary number is a product of signal and sin. Amplitude 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.
