Who should attend?

Audience

    • Geologists, geophysicists, reservoir engineers and professionals involved in data interpretation and management.

Level

  • Foundation
  • This course provides a comprehensive and practical knowledge of reservoir characterization and modeling, focusing on geostatistical methods and tools.
Learning Objectives
  • Upon completion of the course, participants will be able to:
  • use basic geostatistical tools and methods (variograms, kriging, cokriging, external drift),
  • use vertical proportion curves (e.g. layering, well gridding, statistics, vertical proportion curves building),
  • constrain geostatistical distribution using additional information (e.g. geology, seismic and dynamic data).
