Pitfalls in the study of seismic amplitude

Abstract

Amplitude is the key to all seismic interpretation objectives other than structure. Amplitude tells us about stratigraphic bodies, fluid content, and porosity zones. But amplitude is also affected by data collection, data processing, surface conditions, the geology of the overburden, and shallower reservoirs. So, amplitude contains much ambiguity, which can lead to interpretation pitfalls. We may use different types of amplitude, and we may call these amplitude attributes. We may or may not select the type of amplitude optimally for the current interpretation problem. Amplitude is full of information, but can we see what is important? Does the amplitude of our objective stand out sufficiently from other effects? Is our reservoir too thin? We must consider the different display options and use the one that is the most applicable to the interpretation task at hand. Gradational colors are preferred, but there are many color schemes that hinder rather than help the interpretive thought process.
