Abstract

The invention relates to a seismic processing method (200) for determining a subsurface model comprising: receiving (210) seismic data recorded in a space-time domain; defining (220) a gapped deconvolution prediction operator from the received seismic data; and determining (223) the subsurface model by convolving said gapped deconvolution prediction operator with the received seismic data. According to the invention, said gapped deconvolution prediction operator is defined by deriving (221) said gapped deconvolution prediction operator in a model domain which is different from said space-time domain, and by converting (222) the deconvolution prediction operator derived in the model domain to the space-time domain using a linear conversion operator.The invention relates to a seismic processing method (200) for determining a subsurface model comprising: receiving (210) seismic data recorded in a space-time domain; defining (220) a gapped deconvolution prediction operator from the received seismic data; and determining (223) the subsurface model by convolving said gapped deconvolution prediction operator with the received seismic data.
