We present a Williston Basin case study solution using a new anisotropic depth migration velocity analysis work flow. Utilizing available well data, Vp, and transverse isotropy (TI) parameters in the overburden are modeled and validated in sufficient detail to have a direct impact on the quality of the seismic image at depth. Comparison with isotropic modeling demonstrates the need for highly detailed spatial and vertical modeling of overburden TI heterogeneity prior to azimuthal attribute analysis and other reservoir characterization workflows.
