STRUCTURAL STYLES IN PETROLEUM

DESCRIPTION

This course provides an overview of all hydrocarbon-bearing structural assemblages and their associated trap types. The processes that produce the structures and control their styles are interpreted in terms of basic rock-mechanical principles. Classic outcrops, physical models, 2-D and 3-D seismic, and mature-field log-based interpretations from around the world provide analog examples for practical interpretation. Participants will learn the major structural trap geometries and the structural concepts for predicting the geometry where data are absent, misleading, or conflicting. The principles of section balancing and restoration are covered as tools for validating interpretations and for documenting structural evolution. Practical interpretation skills are developed in numerous exercises, most of which use seismic data

OUTLINE

This training course has the following outcomes:

• Recognize all the different hydrocarbon-bearing structural styles in map and cross-section
• Distinguish the characteristics of each structural style on seismic reflection profiles
• Recognize the arrangement of structural styles and traps within structural families
• Apply mechanical-stratigraphic concepts to understand and predict trap geometry
• Use restoration and balance to validate an interpretation and show the structural evolution
