The EarthStudy 360 tomography system uses input data extracted from EarthStudy 360 directional (directivity) and reflection (full-azimuth RMO) gathers to update the velocity model. The model- (pencil-) based imaging functionality makes tomography extremely efficient, preserving high connectivity (consistency) between the imaging and tomographic update solutions. The substantial increase in information about the subsurface improves accuracy and reduces uncertainty, especially important when determining anisotropy model parameters.
