Abstract: A method of full wavefield inversion using simultaneous-source, ocean bottom sensor (OBS) data, including: obtaining, with a computer, simultaneous-source OBS data recorded by receivers in a seismic acquisition; generating, with a computer, synthetic OBS seismic data from a model based on reciprocity; blending, with a computer, the synthetic OBS seismic data; differencing, with a computer, the simultaneous-source OBS data recorded by receivers and the synthetic data to form a pseudo-deblended residual; updating the model based on the pseudo-deblended residual; and prospecting for hydrocarbons at a location derived from the updated model.
