Seismic Expression of Structural Styles
Course Details
This course will provide participants will the background and skills to interpret both simple and complex structures in seismic data. We provide many analogs and exercises so that participants get a hands-on experience while improving their interpretations skills. Structural interpretations do not just exist in 2D, so our goal is to make sure participants understand how structures can change in 3D while being able to make a kinematically valid structure map with proper contours and fault symbols that illustrate the tectonic setting and structural styles. Throughout the course we will relate the structures back to the impact they have on Petroleum System Elements such trap, migration, and seal. Along the way we will conduct multiple hands-on exercises so that these concepts can be retained. We will end the class by discussing a proper workflow for structural seismic interpretation, constructing structural domains, and by giving participants an opportunity to discuss their own work with feedback provided.
Who Should Attend
Geologists and geophysicists who spend time making and evaluating structures in seismic data. While many geophysicists have a great technical background, this class will help ground them in structurally valid interpretations. This class will also teach the geologists about recognizing structures in seismic data, while addressing seismic artifacts and non-structural features that may occur in the seismic data, particularly in settings with complex structures.
