"A High-Resolution Velocity Analysis (HRVA) has been developed for the determination of the root-mean-square subsurface-velocity energy spectrum from gated seismic data which has been normal-moveout corrected. All calculations are performed in the frequency-space or frequency-wavenumber domain; seismic gates are transformed from the time-space domain via the Fast Fourier Transform algorithm. HRVA is not restricted to the investigation of apparent horizontal velocities which have associated stepout values that are integral multiples of the time sampling interval, as are the existing correlation techniques. The technique liberally exploits the inexistence of significant energy in the higher frequency harmonies of seismic data, resulting in a considerable time saving. The technique is illustrated with West Texas seismic data. The results are discussed as a means for deriving a more accurate rms sub-surface velocity function for NMO corrections and subsequent stacking, and as a means for various lithologic investigations. Several procedures are presented for effecting static corrections of the seismic data in conjunction with HRVA"--Abstract, page ii.
