... imaging and reservoir characterization products. We develop a reciprocal version of the Rayleigh-Marchenko (RM) method, called the upside-down RM method, in which all spatial integrals are performed over the (usually much better-sampled) source carpet; this results in a redatuming scheme that naturally...

The good match between the focusing functions retrieved by the two different methods confirms that the equations governing the Rayleigh-Marchenko redatuming can indeed be inverted. Moreover, despite small discrepancies in the focusing...

Subsequently, Vargas and Vasconcelos (2020) combine the versatility of the Rayleigh Marchenko method with the scattering-based Marchenko method to handle redatuming in complex media and perform a more reliable approximation of the retrieved...

The approach that we propose here thus requires more prior information than the Marchenko method, but it can provide in turn...

By staying at the surface, this method is independent of background velocity information and helps in gaining a better understanding of the imprint of internal multiples as compared to Marchenko redatuming ( Wapenaar et al., 2014 ).
