Course Description
The main objective of this course is to provide to the professionals of exploration and production of the oil industry the necessary knowledge on visualization, integration and interpretation techniques recently developed for interpreting 3D seismic data.
Participants will gain a solid foundation in the understanding of the applications and the role of the seismic interpreter on studies related to seismic attributes before and after stacking, AVO, sequence seismic stratigraphy, seismic monitoring (4D), well to well seismic and integrated multidisciplinary studies.
We will guide participants through recent examples, case studies and relevant exercises to efficiently convey the concept that the integration of all available data adds value to the predictions that result from seismic interpretation models. The modular design of this course allows quickly adapt to full or reduced versions, meeting the requirements, profiles and interests of different groups of participants. The course will provide to the professionals of exploration and production of the oil industry the necessary knowledge on visualization, integration and interpretation techniques recently developed for interpreting 3D seismic data. This course provides a practical understanding of 3-D seismic structural interpretation in order to identify prospect locations.
