This paper describes how a simultaneous velocity and reflectivity inversion based on one-way modelling can be used to obtain, through a truly automated process, very good fast-track results, including a velocity allowing flattening of the gathers, an angle dependent reflectivity and intercept-gradient volumes that can be used for elastic properties. The 3D real data used to illustrate the method is a recent acquisition in the Barents Sea targeting shallow targets.
