Amplitude and frequency variations related to offset should be analyzed routinely during interpretation of seismic data acquired in deepwater environments. Amplitude variation with offset (AVO) in three dimensions is the key exploration tool in deep waters of the Gulf of Mexico. But application of the tool requires special care. Three-dimensional AVO helps 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 a shale, or residual gas (fizz water) in high-porosity sands. The paper discusses examples from the Gulf of Mexico, will control application, improving detail, and frequency-dependent analysis.
