AVO helps seismic imaging in deepwater environments. C. Skidmore, R.O. Lindsay and D. Ratcliff. OGJ, 3 November 1997, 95(44), 55--60.
Amplitude variation with offset (AVO) in three dimensions is the key exploration tool in deep waters of the Gulf of Mexico. However application of the tool requires special care. 3-D AVO assists the interpreter understand stratigraphy and the meaning of amplitude anomalies. Used in conjunction with well log data, it can help the interpreter distinguish amplitudes related to the presence of hydrocarbons from those that result from, for example, rock-property changes within a non-hydrocarbon-bearing layer, such as shale, or residual gas in high-porosity sands.
