when analysing many datasets on one common canvas, or it can allow travel through time in a 4D
visualisation process comparing one survey to another.
Advance visualisation techniques allow us to interactively explore regional datasets, integrate live well
information into a reservoir model and understand
reservoir dynamics in association with a 4D predictive
model (Fig. 17.36). 3D visualisation technique is also
used to estimate thickness, continuity and lateral
extend of a reservoir and its relationship with horizons
and faults to see the finest reservoir details.
Visualising combinations of complex seismic
attributes like amplitude, continuity and AVO (Amplitude Versus Offset) provide a far more accurate

channel is identified, its shape can be extracted by visualising the 3D volume. (Courtesy: Halliburton)
