CANCELLED CSPG34SC Structural Styles and Interpretation Techniques in Fold-Thrust Belts
WHO SHOULD ATTEND
Exploration and Production Geologists and Geophysicists. The course is designed for geoscientists working in complex structural provinces, who need to apply structural models and 2-D and 3-D methods to improve interpretations for prospect evaluation and field development.
OBJECTIVES
Fold-thrust belts contain complex trap-forming structures, which are not well imaged on seismic data. The objective of the course is to discuss the use of 2-D and 3-D structural models and techniques for constructing maps, balanced cross sections and 3-D interpretations. Models of trap-forming structures for fold-thrust belts will be presented. Problem sets will provide hands on experience in interpreting subsurface structures using seismic and well data.
Course Content:
Fold and Fault
- Structural geometry of common fold-thrust structures including fold-accommodation faults, detachment and faulted detachment folds, fault-propagation folds, fault-bend folds, duplexes, fold-thrust systems and growth-structures.
- Role of mechanical stratigraphy in controlling structural styles in fold belts. Examples of the correct and incorrect use of mechanical stratigraphy to choose between multiple structural solutions.
- Examples of trap-forming structures from the Alberta Foothills, the Utah-Wyoming belt, SubAndean fold belts, Campeche Bay, Mexico, and the Dinaride, Carpathian, Zagros and Papua-New Guinea fold belts.
2-D and 3-D Interpretation Techniques
- Methods for constructing, restoring and validating cross sections, maps and 3-D interpretations including the use of line-length, and area balancing.
- Common pitfalls in the construction of structural maps and cross sections.
- Application of 3-D Interpretation to Major Fields, such as the Cantarell super giant, the Kumaza fields, and Painter Reservoir.
