Wide azimuth seismic data illuminate the subsurface at a wide range of source-receiver azimuths. This valuable azimuthal information may be extracted from seismic data in the form of 3-D angle domain common image gathers (ADCIGs). Residual moveout (RMO) in 3-D ADCIGs generally varies with azimuth when the migration velocity is incorrect. However, to obtain accurate RMO in 3-D ADCIGs wide azimuth seismic data are necessary. Applications of 3-D ADCIGs include seismic interpretation and estimatingdoi:10.1190/1.3627866 fatcat:jruzspw2lbhjrfume7ecxxqehi
