This is the last part of our series on AVO screening in Geoteric. Scaled reflectivity is a volume that results from a rotation of the gradient-intercept crossplot using a certain χ angle. If the right χ angle is used, it will highlight ...
Gradient and Intercept volumes can be generated from the angle stacks as discussed in Part 3. The Gradient and Intercept volumes can be combined in a number of ways to generate different AVO attributes, such as AVO Product or Reflection ...
Geoteric's colour blending and volume comparison capabilities can be used very effectively to screen for AVO anomalies and get an initial understanding of areas where you want to focus on for a more detailed AVO analysis.
The simplest way of AVO Screening involves the computation of difference and ratio volumes to highlight differences in amplitude between stacks. This amplitude difference may represent lithological/fluid differences.
