SCATTERED ENERGY INVERSION OF SEISMIC DATA

摘要

We propose a new algorithm to build a macro-velocity model using scattered energy from a seismic signal. This method does not require an iterative procedure or an estimation of the source wavelet. Consequently, it is an inexpensive and efficient method to delineate a macro-velocity model. We acquire information concerning the velocity differences similar to a gravity or magnetic field and build a macro-velocity model. Thus, subsequent inversion in the time or frequency domains can recover structures with sharp velocity variations from the constructed velocity model as an initial velocity model.
