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

Level : Foundation

Course Content

  • FUNDAMENTALS OF GEOSTATISTICS

      • Basic statistics for data analysis.
      • Introduction to geostatistics.
      • Quantification of spatial variability: variogram.
  • KRIGING & VARIATIONS

      • Introduction to kriging.
      • Data integration: cokriging, collocated cokriging, external drift kriging.
      • Exercises.
  • MAPPING

      • Applications to time-to-depth conversion.
      • Property mapping.
      • Dealing with non-stationary cases (trends).
  • GEOSTATISTICAL SIMULATIONS

      • Why simulations: limitations of kriging.
      • Simulation methods for continuous parameters (as Phi and K).
      • Simulation methods for categorical variables (lithology).
      • Applications.
      • Risk assessment optimization.
      • Applications.

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).

Ways & Means

  • Interactive lectures, practical examples and laboratory exercises will be performed using dedicated software: Isatis.
