Abstract: Conventional migration of short offset seismic data is performed. An interval velocity is obtained using, for example, check shots. An initial model of effective anellipticity parameter as a function of depth is obtained by flattening long offsets within a common image point. From these, interval anellipticity and horizontal velocity are obtained as a function of time. These initial models are used for anisotropic imaging. Any remaining residuals are used to update the interval anellipticity model and the process of migration is repeated until satisfactory results are obtained.
