Structural Interpretation Techniques and Concepts
About the eLearning Course
This skill module introduces structural interpretation as the backbone for evaluating hydrocarbon resources and modeling basins. The skill module examines structural interpretation as fundamental to aspects of development including locating and scoping traps to tracking fluid-flow pathways for hydrocarbon migration through sequential restorations.
The skill module begins with consideration of plate tectonic habitats or structural families including their distinguishing characteristics then examines key techniques in structural interpretation and how they are effectively applied to different habitats, structures, and cases. The skill module provides detailed studies of faults and common structural types, including the interpretive methods allied with specific types and cases.
The focus then turns to interpretive methods related to balanced cross-sections and restorations. The skill module concludes with a brief consideration of seismic methods and data for structural interpretation.
By completing this skill module, learners will be able to recognize the sound application of interpretive methods to specific structures and features and identify areas where an approach or interpretation may miss the mark or merit reevaluation.
