A review of 3D PreSDM model building techniques

Current practice in velocity model building involves close interaction between the interpreter and the geophysicist. To facilitate this interaction, which by its nature is iterative, a full suite of interpretative and visualisation tools is required in order to reduce cycle time. With this in mind, this tutorial paper by Ian F. Jones, dealing with preSDM model building techniques, has been included in our Special Topic on interpretation and visualisation.
