Paper presented at the 2014 SEG Annual Meeting, October 26–31, 2014
Paper Number: SEG-2014-0292
... Summary Seismic imaging (migration) has historically been used to clarify structural targets and to remove diffraction noise from stratigraphic targets. Seismic inversion has taken many forms, including single-trace inversion for impedance contrasts, inverting moveout or waveforms to obtain...

... of them are fairly continuous across the reef and others are discontinuous. Inversion of the seismic data indicates which events represent zones of higher porosity and which are lower porosity or anhydrite-plugged. The full stacked images include angles that are beyond critical for many of the interfaces...

... an integrated workflow that uses high-resolution seismic imaging, prestack inversion, pore-pressure prediction, geological interpretation, and seismic attribute analysis. We use a rock-physics-guided velocity model to derive a low-frequency model for prestack inversion and pore-pressure prediction using a high...

... attached to the base salt layer as irregular, mushroom-shaped bodies called diapirs. The map in Figure 1 gives an indication of how common these highly complex salt bodies are in exploration. Imaging in salt rich domains is difficult since the seismic waves reflected off the steep flanks of subsurface...
