Spectrum of gas migration phenomena across multi-layered sealing sequences

Abstract:

We describe a spectrum of seismic high-amplitude anomalies from the Great South and Canterbury Basins (offshore New Zealand) that have a number of characteristics that make them distinct from previously described hydrocarbon-related amplitude anomalies. We propose a new classification scheme that is based on the specific vertical stacking of the anomalies, and thereby reflects their genetic inter-relationships.
We demonstrate by combining AVO (Amplitude Versus Offset) and other attribut...
