E-254 - SRC: Seismic Reservoir Characterization

24 hours RES/BLSRC
  • Geologists, geophysicists and reservoir engineers with basic knowledge in geophysics.
  • This course provides a comprehensive, practical understanding of how seismic data is used to characterize, model, and rank reservoirs.
Learning Objectives
  • Upon completion of the course, participants will be able to:
  • understand the relationship between physical properties of rocks and geophysics,
  • master the main steps of seismic reservoir characterization workflow, to perform QC and to assess data to be interpreted and related uncertainties,
  • To interpret major results of petro-elastic analysis and modeling, AVO-AVA and Inversion studies and to understand methodological issues in seismic inversion, attributes classification and reservoir properties prediction.
  • No prerequisites for this course.
Ways and means
  • The first 2 hours are dedicated to introducing agenda, methods and tools.
  • Specific needs and expectations of each participant are also assessed and discussed (MCQ and phone interview with the tutor).
Total training duration is 24 hours, spread over a 6-week period
