Emerson’s EarthStudy 360 (ES360) Imager Depth Migration algorithm utilizes full-azimuth, subsurface angle domain wavefield decomposition and imaging to provide additional detail and accuracy through migration and the model-building process, an improvement over industry-standard Kirchhoff depth migration.
Examples of a Kirchhoff PSDM and ES360 PSDM stacks and gathers. Note the increased S/N due to specular weighting in the ES360 example and the multiple attenuation, a benefit of the use of local slant stacking.
