AVO, Inversion, and Attributes: Principles and Applications - AVO

The subject of direct hydrocarbon indicators and AVO has rapidly expanded to include AVO inversion, offset AVO inversion, and 4D AVO inversion. A significant part of the course deals with rock physics as it relates to the other topics in the course. Further insight into the seismic data is supplied by looking at seismic attributes. The technology has provided the interpreter with a very new and exciting package of tools that allow us to look at the seismic image as being truly representative of both the rock properties and the pore filling material.

This course is intended to provide the users with a clear and useable understanding of the current state of these technologies. The focus of the course is on both understanding and application. Each topic in the course outline is reinforced by an exercise that gives the participants many practical and simple methods of integrating the course material into their everyday work. One personal computer is supplied, at added cost, for every two participants.

"I should have taken this class much earlier in my career. It covered subjects that I am exposed to everyday, and now I have a more complete undstanding of these subjects." - Geophysicist, United States

"As a geomodeller, the extractions on rock properties e.g. porosity volume to be used as soft data to populate my model have been very useful." - Geoscientist, Nigeria

Target Audience

Geophysicists, geologists, explorationists, seismic interpreters, technical support personnel, seismic data processors, exploration, production, and acquisition managers who need a clear understanding of the details of implementation and application of this technology.
