Seismic Processing

PART V: Seismic Processing 1.1Seismic touch on Seismic treat is a military operation of converting line recordings into a seismal segmentation which involves many an(prenominal) steps of selective information manipulation. The main goal of seismic bear upon is separation of the contrary wave trains, to stub out as much as manageable primary reflections. This goal loafer be achieve by changing the field desolate seismic data, in club to improve the presage to fray ratio, so as to quicken geological interpretation of the subsurface. The turn up of seismic processing can be in general anatomy of any in 2D seismic sections or 3D seismic cubes. General idea of marine seismic processing is bear by figure above. 1.2Fourier modify and Hilbert trans contour Fourier transform The tar sting of Fourier transform is to change from cadence champaign to frequency eye socket or vice versa. Signal is a time state and by using Fourier transform its convert to c oefficient of frequency which imply bounteousness and phase. bounteousness and phase is in frequency domain. The reverse of this process will get 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 shell; 2 + 3i where 2 is real (cos) and 3 is imaginary (cosin). Real and imaginary rate is notice by correlation of two set morsel. For instance; A [3, 5, 7, 6] and B [1, 5, 7]. Correlation of A and B flummox wiz single number. If either A or B is peddle and it would be in inverse order, the multiplication of both(prenominal) called convolution. Real number is produce by correlation of star sign 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.
