Claim One:
1. A method, stored in a memory and executed on a processor, for generating a modeled seismic image based on a reverse time demigration (RTDM) of a seismic depth image of a subsurface formation, said method comprising: acquiring data that form the seismic depth image, with one or more seismic receivers, upon firing one or more seismic sources; adding a coupling term, based on a reflectivity term acting as a linear source, to the RTDM equation for the seismic depth image to create a coupled RTDM equation; estimating a pseudo-density function by converting, based on solving a nonlinear inversion, said seismic depth image to said pseudo-density function; stabilizing said coupled RTDM equation by replacing, in said coupled RTDM equation, said reflectivity term with said pseudo-density function to create a stabilized coupled RTDM equation; solving said stabilized coupled RTDM equation and reconstructing wavefields at said one or more seismic receivers based on said seismic depth image, one or more migration velocities and locations associated with said one or more seismic sources; and outputting a modeled seismic image of said subsurface formation and associated with said seismic depth image, wherein said modeled seismic image comprises surface related multiples or interbed multiples.
