9 Earth Model

This chapter provides an overview of earth model features and earth model interpretations and how they may be used and constructed using RESQML.

This chapter explains some basic concepts and provides some examples for creating and updating an earth model interpretation—following the feature/interpretation/representation/property knowledge hierarchy defined in Chapter 5 Knowledge Hierarchy : Features, Interpretations, Representations , and Properties —beginning with structural and stratigraphic features, then adding related interpretations and representations, including related geometry.

This concept of earth model interpretation is the most important to ensure an update of the earth model when more information (new data) are acquired during the lifecycle of a prospect.

The goal is to transfer the information built up from each step of the modeling process, which includes the semantic and numeric information necessary to describe a subsurface area for development and/or reservoir management activities.
