The Tulip 3D seismic survey was the first Coil Shooting - circular geometry- project acquired with a single towing vessel in Indonesia. Coil geometry acquisition records a dataset with a wide range of source to detector azimuths. Amongst the numerous advantages of extended azimuth sampling methods is the advantage of illumination diversity. This has a desirable impact with tomographic velocity model building for depth imaging. The additional azimuth information allows an additional constraint on the tomography (if the software supports it) by providing a network of intersecting rays not available with narrow azimuth geometries.This case study will describe the multi-azimuth tomography model building and subsequent depth imaging used in the Tulip coil 3D project. It is believed this is the first commercial application of multi-azimuth tomography model building and depth imaging in Indonesia.
