A 10,000 ft. [Subsurface] View on Why You Should Learn Geostatistics

Michael Pyrcz, PhD, P.Eng (daytum Founding Advisor)

Statistics provide quantitative lens for a new perspective on subsurface data and to better understand subsurface uncertainty.

Learning Geostatistics will help you leverage:

  1. Deductive Statistics – Pooling data for the purpose of quantification of univariate, multivariate and spatial phenomenon
  2. Inferential Statistics – Methods to make inferences concerning the population from a sample.  In the subsurface we only directly sample about 1 trillionth of the reservoir; therefore, essential!
  3. Frequentist Statistics – Drawing conclusions based on frequencies or proportions.  So many problems can be solved by counting!
  4. Bayesian Statistics – Drawing conclusions based on updating belief with new information.  Bayesian theorem can solved difficult problems such as the probability of a subsurface depositional setting, given well core data observations.
  5. Statistical Representativity – Sampling for representativity and treatment of bias.  All subsurface datasets are biased!
  6. Statistical Significance – Testing the significance of results with hypothesis testing and confidence intervals.  Does the result matter?
  7. Spatial Modeling – The subsurface has spatial structures; therefore, by capturing them we get much better models.
  8. Statistical Modeling – Data-driven modeling and prediction.  Regression to machine learning, let’s join the data-driven paradigm!
  9. Uncertainty Models – Modeling, summarizing and making decisions in the presence of uncertainty.  Uncertainty is ubiquitous and due to our ignorance.
  10. Big Data Analytics – Working with high volume, variety and velocity data inherent to subsurface exploration
