Sum %X The accurate migration of seismic data is conditional on the parameters which are nominated. The effective velocity used in residual processing for migration is small compared to the original migration velocity. Considering traveltime computation is a significant part of seismic imaging algorithms. Conventional implementation of Kirchhoff migration is essential for precomputing a traveltime table from the categories involving traditional ray-tracing methods and finite difference eikonal solvers. In this paper, we examine the accuracy using, the eikonal solver and paraxial ray tracing traveltime computation in pre-stack Kirchhoff depth migration. This hybrid traveltime technique can be applied to a variety of problems related to faults, fractures, and complex region. To evaluate the relevance of this identical traveltime technique, we applied on a Marmousi data set. © Published under licence by IOP Publishing Ltd. %K Earth sciences; Geology; Seismology, Diffraction studies; Effective velocity; Faults , fractures; Kirchhoff depth migration; Kirchhoff migration; Paraxial ray tracing; Ray-tracing method; Travel-time tables, Ray tracing, algorithm; computer vision; crosshole seismic method; Kirchhoff equation; ray tracing; seismic data; travel time; velocity profile; vertical distribution %V 38 %T Enhancement in Seismic Imaging using Diffraction Studies and Hybrid Traveltime Technique for PSDM %O cited By 1; Conference of 4th International Conference on Geological, Geographical, Aerospace and Earth Science 2016, AeroEarth 2016 ; Conference Date: 4 June 2016 Through 5 June 2016; Conference Code:123703 %D 2016 %R 10.1088/1755-1315/38/1/012002 %N 1
