CFSG – Module 4 – Facies simulations | Training course
Learn how to compute realistic geological facies models.
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 fourth one of the series. At the end of it, you will be able to generate robust geological models using several advanced techniques.
- 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.
- Model determination
– From geology to indicators
– Experimental statistics of indicators: proportions, stationarity
- The Sequential methods
– Sequential Indicator Simulations:
. Modeling the variogram of indicators
. Adaptation of the Sequential Simulation technique to facies
– Multiple-point Simulations (MPS):
. Choice of one or several Training Images
. Sequential simulation (pattern matching)
- The Boolean model
– Ingredients: Point process, Objects
– Modeling the Point process: Poisson (deterministic intensity) or Cox (random intensity)
– Non-conditional simulations
– Conditional simulations: iterative and sequential methods
– Extension to the multi-facies case
- The Plurigaussian model
– Reminders: the Gaussian Simulation approach for continuous variables (e.g. Turning Bands)
– Ingredients: Indicators, dimension of the latent Gaussian field (mono-gaussian or pluri-gaussian), truncation rules
– Modeling: Facies proportions and variograms of the underlying Gaussian Random Function
– Non-conditional simulations
– Conditional simulations:
. Gibbs sampler for translating categorical constraints into gaussian values
. Conditional Gaussian simulations
Several exercises to learn how to compute a facies proportions model and run Sequential Indicator Simulations and Plurigaussian Simulations 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.
