Abstract: Computing systems and methods to producing a reverse time migration model dip-guided image using processed vertical seismic profile data are provided. In one embodiment, vertical seismic profile data for a subsurface geological formation is obtained. One or more dip estimates corresponding to the subsurface geological formation are also obtained. One or more model dip-guided reverse time migration imaging conditions are determined and applied to the obtained vertical seismic profile data to produce the processed vertical seismic profile data.
