Marine-FTG®
Introduction
Gradient data responds to density changes independently of velocity and is not subject to imaging problems
caused by the scattering of seismic energy. FTG technology provides an independent means to resolve
subsurface structure by defining the size, shape and thickness of salt and subsalt structure. A well defined salt
feature can be used to provide a more accurate initial velocity model for pre stack depth migration, thereby saving
iterations, time and money.
Gradient data also responds strongly to the presence of basalt. The size, shape and thickness of basalt can be mapped and its signature removed from the seismic data in order to accurately image the sub-basalt structure.
