The lecture Lecture series is a continuation of lecture series 1,2 described in my previous two presentations. The goals and steps in Seismic data processing like NMO, noise elimination (via F-K filtering), velocity analysis, and inverse filtering namely the Deconvolution concept have been discussed in our lecture. The Effects of deconvolution on, Amplitude, phase spectra, and its corresponding time series wavelets has been pictorially presented with an objective to improve the S/N ratio, and resolution by broadening the frequency Spectrum. The most important steps of Velocity picking and analysis have been illustrated in this lecture. Finally, as a case study example, two marine seismic sections have been shown for clear understanding of subsurface imaging goal.
