Original Abstract Submitted
a method can include receiving seismic data, where, in the seismic data, seismic energy reflections represent events associated with structures in a subsurface geologic environment; performing reference wavefield simulations of a reference wavefield, based on a reference model of the subsurface geologic environment for traveltimes of the events; for each time-step of the reference wavefield simulations, passing a reference wavefield simulation result to a correction term simulation that utilizes a limited number of time-steps to generate a correction term simulation result; after the limited number of time-steps, passing the correction term simulation result to a summed-correction wavefield simulation to generate a summed-correction wavefield result; generating a corrected wavefield as a sum of a final reference wavefield simulation result and a final summed-correction wavefield simulation result; and outputting a seismic image based on the corrected seismic wavefield, where the corrected seismic wavefield improves accuracy of the structures in the subsurface.
