The Nimitz 3D project involved reprocessing of 480 sq. km of marine 3D data, from the offshore North Taranaki basin, New Zealand. The data was acquired by the CGG vessel Pacific Titan in March and April 2007. The processing was carried out in Fugro Seismic Imaging's Perth centre. Three key products were required from this project: premigration gathers for input to depth processing; velocity field (picked on migrated data) to be used as an initial velocity model; and a final post processed cube for structural interpretation. The key challenges of this project were to provide better imaging of the top Eocene (2 to 3 seconds) and to complete the project in time to provide a smooth transition to the depth work. Of particular concern in imaging was a velocity inversion seen at approximately 3 seconds which may not have been picked accurately in previous processing.
