Advanced Seismic Interpretation Course
Introduction:
The main objective is to provide E&P professionals with knowledge on visualization, integration and interpretation techniques recently developed for seismic data. Learning objectives are at knowledge and application levels. The participants will gain a solid understanding of the applications and role of the seismic interpreter in studies related with pre- and post-stack seismic attributes, AVO, seismic sequence Stratigraphy, seismic geomorphology and rock physics measurements, 4D or time lapse seismic, and multidisciplinary integrated studies. Recent and relevant case histories, data examples, and exercises will guide the participants in the understanding that the integration of all available data into the seismic model will add value in the needed coherent and successful seismic predictions that result from an interpretation.
Course Objectives:
The training course will help professionals to gain a solid understanding of the applications and role of the seismic interpreter in studies that involve post-stack seismic attributes, AVO, seismic sequence stratigraphy, seismic geomorphology, 4D time-lapse seismic, Vertical Seismic Profile and Interpretative processing.
By the end of this training course, the participants will:
- Have working knowledge of the full range of representative special interpretative methods
- Have experience on hands-on real data sets and real workflow in the oil industry, which he may carry out himself and/or supervise
- Be capable to account for the geophysical input in multi-disciplinary teams
- Be proficient on Seismic interpretation
