Abstract: Method and apparatus for performing a seismic full waveform inversion independent of a source wavelet to generate a final velocity model of subsurface formations of a survey region are provided. The method includes positioning seismic data recording sensors in the survey region; blasting at points of incidence in the survey region to generate seismic waves; and sensing and recording the seismic waves using the seismic data recording sensor. The recorded seismic waves are seismic data. The method further includes transmitting the seismic data to a computer system including one or more memories and storing the seismic data in one or more memories; storing a source wavelet in the one or more memories; performing, by the computer system, a forward modeling operation using the source wavelet; and generating, by the computer system, the final velocity model for the seismic full waveform inversion using the forward modeling operation.
