Velocity-estimation improvements and migration/demigration using CRS with continuing deconvolution in the time domain

Abstract:

To obtain an image of the earth's subsurface, time-imaging methods can be applied, as they are reasonably fast, less sensitive to velocity model errors than depth-imaging methods and, usually, easy to parallelize. A powerful tool for time-imaging consists of a series of prestack time-migrations and demigrations. We apply multi-parameter stacking techniques to obtain an initial time-migration velocity model. The velocity model building proposed here, is based on the kinematic wavefield attribu...
