Abstract

Summary

Dual WAZ and tilted orthorhombic anisotropy model building and imaging has approved to provide a more geologic conforming high resolution velocity models, give a better illumination and flatten the common imaging gathers for all azimuths, and improve the CIG flatness and enhance seismic continuity. In this paper we will present wide azimuthal orthorhombic anisotropy model building workflow and multiazimuth modelling for orthogonal WAZ, compare the TORT initial and final models in depth sections and slices, and show some examples of final TORT seismic imaging and CIG comparison to demonstrate the orthorhombic anisotropy modelling improves the CIG flatness across the different azimuths.
