EARTH MODEL ESTIMATION THROUGH AN ACOUSTIC FULL WAVEFORM INVERSION OF SEISMIC DATA

摘要

An improved method of estimating an earth model utilizes an acoustic Full Waveform Inversion ( FWI ) of seismic data in a pseudo-time coordinate system, in which the earth model m(m?) is parameterized with two lateral coordinates (x,y)and a vertical coordinate (z?) which expresses vertical travel time of acoustic signals used to generate the seismic data.
