Training session on geostatistics for the Oil & Gas Industry

Course Contents

1/FIRST WEEK

The first week is dedicated to beginners or people wishing to learn more about geostatistics and ISATIS, but who do not use it frequently. The basic concepts and methods of geostatistics are presented. The course highlights hints and pitfalls in geostatistical data analysis:

• 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

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.

2/SECOND WEEK

The second week deals with more advanced geostatistics and tackles the following issues:

• Specific Applications

• Filtering of 3D seismic

• Facies simulations
  • Multiple-point Simulations
  • Sequential Indicator Simulations
  • Plurigaussian Simulations
  • Use of seismic to constrain the facies simulations

• Simulations of the properties for populating the facies simulations
  • Pros and Cons of the main methods, i.e. Turning Bands and SGS
  • How to apply the properties to facies simulations.

• Post processing of simulations

• PETREL-ISATIS Link

• Batch capabilities
  • Running EDA in batch
  • Use of simulations and Post processing

Note: the main issues are illustrated by practical applications on actual data.

• Open Discussion

Based on the experience of users, one day is dedicated to a round table for answering practical questions in geostatistical analysis and reservoir modelling.

Lecturers
