Abstract
In practice, seismic data has been used to map the geometry of events in the subsurface, mainly from reflection continuity and the character of reflection packages. Seismic modelling techniques are attempts to mathematically and geometrically represent the geology of the subsurface and to depict the interaction of that geology with a propagating seismic wavefront. In the Niger Delta, recent development in stratigraphic exploration has induced the examination of more substle features of reflection mainly polarity, amplitude and waveform to define the limits of seismic resolution, and hence predict the geometry of the subsurface fluid and solid interfaces.
