Paper Number: SEG-2007-2320
... offset-domain common-image gathers (SODCIGs) and angle-domain common-image gathers (ADCIGs). I demonstrate the effects of sparsely sampled wavefields on both SODCIGs and ADCIGs. I also demonstrate that the final image formed by simple stacking over the reflection-angle and azimuth axes without any...

... a prestack migrated image, a limited number of independent experiments that contain all the velocity information needed for MVA. The basic element of the method is the modeling of one isolated Subsurface-Offset Domain Common Image Gather (SODCIG) by using the prestack image as an initial condition. Taking...
