E-340 - SRC Seismic Reservoir Characterization

24 hours GEP/BLSRC
  • Geologists, geophysicists and reservoir engineers with basic knowledge in geophysics
  • To provide a comprehensive and practical understanding of how seismic data is used to characterize, model, and classify reservoirs
Learning Objectives
  • To understand the relationship between physical properties of rocks and geophysics
  • To 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
Ways and means
  • Before training starts, 2 hours are dedicated to introduce the training agenda, methods and tools
  • The exact needs and expectations of each participant are also assessed and discussed (MCQ and phone interview with the tutor)
Total duration of the training is 24 hours, spread over a 6-week period
