Training: Contaminated Site Characterization

0

Nowadays, Geostatistics is more and more applied for soil pollution mapping (chemical and radiological) and for risk analysis (estimation of contaminated volumes exceeding a pollution threshold). This course presents the basic concepts and methods of Geostatistics to achieve these goals. The subject matter ranges from variography to kriging and simulations for risk analysis. A particular attention is paid to the integration of these methods for the characterization of contaminated sites: accounting for the historical data, sampling optimization, cartography of in situ pollution and estimation of contaminated volumes.

Nowadays, Geostatistics is more and more applied for soil pollution mapping (chemical and radiological) and for risk analysis (estimation of contaminated volumes exceeding a pollution threshold).

This course presents the basic concepts and methods of Geostatistics to achieve these goals. The subject matter ranges from variography to kriging and simulations for risk analysis.

A particular attention is paid to the integration of these methods for the characterization of contaminated sites: accounting for the historical data, sampling optimization, cartography of in situ pollution and estimation of contaminated volumes.

Half of the course is dedicated to practical computer exercises, using Isatis in order to reinforce the previously presented theoretical notions.

The course is designed for practitioners confronted with the characterization of contaminated sites and who wish a practical introduction to geostatistical methods. No prior knowledge of geostatistics is required. However a basic understanding of statistics is recommended.

  • Introduction: what is geostatistics? The advantages of using geostatistics over existing methods.
  • The foundation stone of geostatistics: quantifying the spatial behaviour via the variogram. Calculating, modelling and interpreting the directional variograms.
  • Interpolating between the data: the theory and practice of kriging.
  • The fundamental concept of support: differences between sampling support, estimation and remediation support.
  • Multivariate geostatistics and cokriging. Incorporating the correlation between several variables improves the final estimate.
  • The limitations of kriging and introduction to risk analysis: practice of conditional simulations to estimate the probability of exceeding a pollution threshold and the global contaminated volumes together with their uncertainty.

Geovariances offers a complete set of high quality training programs in geostatistics for beginners and experienced users.

Geovariances courses cover basic and advanced geostatistics and provide participants with plenty of hands-on practice with real oil reservoir data.
