In this E-Lecture, Marit Guttormsen presents the results of a 3D OBS dataset acquired in the Barents Sea. The result was a significant uplift in the structural image by imaging the Pressure energy converted to Shear energy (PS). In order to achieve the
image an integrated Velocity Model Building (VMB) flow, using several datasets and a variety of techniques, was implemented. The lecture attempts to summarize the key steps in such an integrated VMB workflow.
