Reliable interpretation relies on accurate imaging and we can decline this one step further by saying that accurate imaging relies on an accurate velocity model. In the case of depth imaging and with the presence of salt, the velocity model itself should honour the velocity contrasts present at the Top/Base of the salt body. Here we present the application of a Salt Shape Tomography method on two datasets from the Sultanate of Oman. This method, which is part of multi-layer non-linear tomography, aims at reducing the time spent on manual interpretation or scenario testing for salt delineation, while producing better focusing for an improved subsalt image.
