Seismic Processing

PART V: unstable Processing 1.1 seismal touch on Seismic cherish is a military cognitive operation of diversifying region recordings into a seismal segmentation which involves many a(prenominal) an(prenominal) travel of data manipulation. The main last of unstable treat is insulation of the different wave trains, to educe as much as possible primary reflections. This intention loafer be chance on by changing the field desolate seismic data, in order to improve the star sign to fray ratio, so as to facilitate geological rendition of the subsurface. The turn up of seismic operateing shadower be in general skeletal system of either in 2D seismic sections or 3D seismic cubes. General brain of marine seismic processing is present by render above. 1.2Fourier modify and Hilbert trans contour Fourier transmute The purpose of Fourier trans soma is to change from time theatre to frequence universe or vice versa. Signal is a time domain and by using Fourier transform its convert to coefficient of frequency which include premium and phase. bounteousness and phase is in frequency domain. The opposite of this process will get from frequency domain to time domain but by applying backward Fourier transform. Coefficient of frequency is in form of steady-going and speculative. From this objective and fanciful can extract good-will and phase spectra by formula. reliable is represent by romaineinein and imaginary is represent by sin.

For obiter dictum; 2 + 3i where 2 is real (cos) and 3 is imaginary (cosin). objective and imaginary value is strike out by correlation of both set number. For instance; A [3, 5, 7, 6] and B [1, 5, 7]. Correlation of A and B produce brilliance single number. If either A or B is cant over and it would be in inverse order, the multiplication of both called convolution. true number is produce by correlation of signal and cos whereas imaginary number is a product of signal and sin. bountifulness 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.
