Reservoir Services - AVO/Attributes

AVOAmplitude vs. Offset (AVO)
Understanding the behavior of amplitude with offset (or angle of incidence) has been a popular risk assessment tool for many years. AVO is used successfully as a hydrocarbon indicator in many plays, especially younger clastic environments with gas-filled porous sands. A common misconception, however, is that AVO doesn’t work in other environments, such as tight sands or in carbonate plays. Geotrace can prove differently. By using input gathers that are properly imaged, well conditioned and bandwidth extended, we have greatly expanded the scope of this invaluable tool in determining risk.
