CFSG – Module 5 – Domaining | Training course

Get introduced to a powerful machine-learning-based technique for geological domaining.


The Specialized Training Cycle in Geostatistics, known as CFSG, is a high-level training program in mining geostatistics delivered by the Geostatistics Team from Mines Paris and Geovariances. Its objective is to give you a comprehensive and deep knowledge of geostatistics for mineral resource estimation so that, when you return to work, you will be able to build the block models that your company needs for confident mine planning. By attending the program, you learn the theory behind the techniques presented to you and practice them through numerous exercises and a real-life project.

The 2023 edition of CFSG is delivered online in 6 modules over 10 weeks starting end of January 2023. This module is the fifth one of the series. At the end of it, you will be able to derive domains from surfaces and drill hole information.


  • Half of the training program is devoted to methodological presentations, the other half to practical exercises to deepen the understanding of concepts.
    – The methodological courses are given
    by Mines Paris professors and are scheduled to match the audience’s time zone. For more convenience, these courses are recorded and made available to participants.
    – Geovariances’ consultants will drive the practical sessions, either from our French office (for those whose time zone is compatible with the French one) or from our Australian and Brazilian offices for the other participants.
  • A typical training week would then be:
    – Monday, Tuesday, and Wednesday: theoretical course (on a half-day) and hands-on practice with Isatis.neo Mining Edition (on the half-day following the theoretical course).
    – Thursday or Friday: Homework using Isatis.neo Mining Edition with compulsory rendering at the end of the day.
    – Friday: Live correction and comments from the teaching team. Validation of prior learning.
  • CFSG is a full-time training. You are required to be present for the duration of the sessions.
  • CFSG is a certification training. The knowledge acquired in each module is validated through an examination. At the end of each module, you will get a training certificate with a distinction that officially recognizes the full completion of the module.
  • Course material and a temporary software license are provided.
  • A minimum number of 5 participants is required for a module actually to take place.

Note that sessions scheduled at AWST Perth time are designed for people from the Asia-Pacific region, as sessions scheduled at CET/CEST Paris time are meant for people from Africa, the Americas, and Europe. Practical sessions are planned to adapt to the Americas, the whole of Europe, and the Asia-Pacific.

Who should attend

CFSG training program is meant for mining geologists and engineers who are willing to achieve a high level in geostatistics.



A 3D domain is modeled by its boundaries, considered as a pair of 2D surfaces or a closed manifold in 3D.

  • Data classification: statistical multivariate geographical classification using Geostatistical Hierarchical Clustering (GHC)
    – Classification into rock types from multivariate attributes
    – Integrating spatial dependency through an adjacency graph
    – Post-processing
    – Updating the classification with Support Vector Machine learning methods (SVM)
  • The Potential method
    – Data: intercepts of drill holes with boundaries, normal and tangent to the surface
    – The implicit model
    – Estimating the latent potential using cokriging
    – Dealing with several surfaces: conformal layers, layers with pinch-outs, or faulted
    – Uncertainty quantification (probability to belong to the domain) with simulations of the potential field

*** At the end of the theoretical course, you will be introduced to the Stochastic Partial Differential Equations (SPDE), an innovative and efficient algorithm in Isatis.neo used for simulating continuous variables. It is also implemented for estimating local facies proportions, a step required for geological modeling through Plurigaussian simulations.***


Several exercises to learn how to run sample clustering for automatic domaining and domain modeling with Isatis.neo Mining Edition.


This course is ideal for newcomers to mining geostatistics.

The course is delivered in English and requires a good level of this language. Good notions of mathematics are also recommended.

We recall that the CFSG program is made of 6 modules:
Module 1: Geostatistics Fundamentals
Module 2: Advanced in-situ resources
Module 3: Recoverable resources
Module 4: Facies simulations
Module 5: Domaining
Module 6: Coupling Machine-Learning and geostatistical techniques using Python

Modules can be attended à la carte, according to your needs, independently from each other. Module 1 is mandatory if you have never used Isatis.neo or have no prior experience in geostatistics.

We offer a 25% discount on the purchase of all six modules and a 15% discount on the purchase of the four modules 1, 2, 3, and 4.
