OBJECTIVE

To present the basic concepts and methods of geostatistics (variograms, kriging, multivariate geostatistics, simulations). The course highlights hints and pitfalls in geostatistical data analysis.

KEY FEATURES

The capabilities of geostatistics to handle petroleum data characterised by their heterogeneous nature are particularly illustrated: integration of wells and seismic data, processing of data in presence of faults.

WHO SHOULD ATTEND

Geologists, geophysicists and engineers requiring a practical introduction to geostatistical methods for data analysis, interpolation and reservoir characterisation. Prior study of geostatistics is not required. Basic knowledge of statistics is recommended.

COURSE CONTENT

Review of basic geostatistics.
Main concepts of geostatistics.
Exploratory data analysis, the variogram as the fundamental geostatistical tool.
Variogram modelling.
Theory and practice of kriging.
Specific kriging methods: with faults, inequalities, measurement errors, filtering.
Multivariate geostatistics and cokriging.
Introduction to non stationary geostatistics.
Overview of geostatistical simulations.

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