METHOD OF GEOPHYSICAL EXPLORATION

摘要

A method of geophysical exploration is provided for reducing distortion or smearing of reflection event amplitudes in seismic data resulting from residual normal moveout. In particular, the seismic data are sorted into ordered gathers of seismic signals and corresponding reflection events are aligned along hyperbolic loci of traveltimes. The hyperbolically aligned reflection events are then corrected for residual normal moveout by aligning corresponding reflection events along nonhyperbolic loci of traveltimes.
