ABSTRACT

Amplitude Versus Offset (AVO) technologies were applied extensively in the Gulf of Mexico to evaluate primarily bright spots. These analyses were routinely performed on 2-D seismic data, where the technique met with considerable success. However, as the prospect inventories dwindled, the success rate declined. Remembering that we drill our best leads first, it is only to be expected that the risk associated with these prospects would be higher—even with advanced technologies. It is probably for this reason that the application of AVO technology went through a hiatus.

Today, time domain 3-D AVO is used in many areas of the world. For the complex imaging areas of the Subsalt Trend, another advancement was needed. The combination of 3-D PreSDM and 3-D AVO is that advancement. Depth domain 3-D AVO is now possible (Fig. 1).
