This paper introduces an internal multiple prediction method based on imaging profile prediction and Kirchhoff demigration. First, based on an inputted prestack time migration profile, the method predicts the prestack time migration profile that only includes internal multiples by inverse scattering series method. Second, the method uses velocity-weighted Kirchhoff demigration to create shot gathers...
A novel evaluation system and its application method is put forward in order to provide a useful tool to determine what kind of cargo an undeveloped port-shoreline is suited for. First, this paper presents a comprehensive evaluation system consisting of the two subsystems: evaluation subsystem of natural and technical attributes and evaluation subsystem of social and economic attributes, and proposes...
