AVO-Gradient with Timeslice – Stratigraphic Trap

People tend to think of AVO as a tool to predict fluid content, primarily gas, but AVO can be used for much more. AVO is a pre-stack attribute, a function of rock properties and acquisition geometry. The AVO response is a complex function of the physical propertiesof the overlying and underlying rock at an interface. If we assume that the properties of the overlying rock are constant, then the AVO response is a function of changes within the underlying rock. These changes may be a result of the change in fluid content, but the changes can just as easily be because of a variation in the physical properties of the underlying rock. The changes may be stratigraphic (change in rock type/depositional environment), porosity related, or even influenced by existing fractures. Thus, defining an AVO anomaly is just the first step in deciding whether one has a viable exploration or development target. Is it a gas filled reservoir? A porous channel deposit? High porosity zone within a reef? Or maybe an area of increased fracture density in tight reservoir?

Please check out AVO-Detect. We believe it can be a useful tool to help you in making exploration and development decisions. We think you will like it.
