Geological Model Building: A Hierarchical Segmentation Approach

Abstract

A new approach towards model building with the promise of significantly shortening the turnaround time of 3D model building is presented. By introducing a unified framework, efficient representation of models throughout the lifecycle of a reservoir is enabled, all the way from velocity to simulation models. All levels of resolution are maintained and handled simultaneously and information is structured according to geological understanding. This enables the interpreter to work with pre-generated geological objects, rather than spending time creating them in the first place. Consequently, more time is spent being creative, gaining a better understanding of the reservoir. Furthermore, the framework enables use of new semi- or fully automatic interpretation schemes and provides real-time user interaction with large volumes.
