E-340 - SRC Seismic Reservoir Characterization

24 hours GEP/BLSRC
Level
Foundation
Audience
  • Geologists, geophysicists and reservoir engineers with basic knowledge in geophysics
Purpose
  • 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)
Observation
Total duration of the training is 24 hours, spread over a 6-week period
