Structural Styles and Hydrocarbon Traps
in Compressive Basins |
|
Instructors: Shankar Mitra, Ph.D.
Course Length: 5 DAYS
Course CEUs: 4.0
Course Description
Compressive structural provinces contain complex trap-forming structures, which are not well imaged on seismic data. Interpretation of these structures can be improved by the application of accurate structural models and balanced cross section techniques. This course presents 2-D and 3-D structural models of common trap-forming structures for fold-thrust belts, foreland basement structures and inversion and reactivated structures. Techniques for constructing balanced cross sections, maps and 3-D interpretations through these structures are presented. The use of mechanical stratigraphy to choose between different structural models is discussed. Problem sets provide hands-on experience in interpreting subsurface structures using surface, seismic, outcrop and well log data.
Who should attend
Exploration and production geologists, geophysicists, supervisors, and managers from other disciplines. This course is for geoscientists working in complex structural provinces who need to apply structural models and 2-D and 3-D balancing methods to improve interpretations for prospect evaluation and field development.
