Abstract
Methods for mapping a subsurface formation can include: generating a velocity model representing the subsurface formation based on the seismic data; determining an upper bound for traveltime within the velocity model from a seismic source; and generating a seismic image of the subsurface formation by migrating the seismic data using Kirchhoff depth migration, where traveltime is calculated through ray tracing, and the maximum traveltime determines the stopping point for ray tracing. Determining an upper bound for traveltime within the velocity model from a seismic source can include: converting the velocity model into a slowness model; integrating slowness along straight paths from the seismic source to boundary points of the slowness model to generate traveltime values; and determining an upper bound of traveltime for seismic rays traveling within the velocity model by selecting a maximum traveltime value from the straight paths.
