Note that this course is also available in Portuguese.
Objective
This course focuses on the geostatistical modeling of reservoirs, including its geological structure (lithofacies) and the distribution of petrophysical properties. The pros and cons of existing simulation algorithms are discussed and illustrated on real examples.
Key features
Most attention is paid to the analysis of proportion curves and the role played by the stratigraphic reference surface. The different steps to carry out for a 3D modeling of reservoir facies with truncated /plurigaussian method are practiced on real data. Attention is paid on the constraining of property simulations by facies.
Who should attend
Geologists, geophysicists and reservoir engineers involved in reservoir characterization. Participants should have a good knowledge of basic geostatistics (variograms, kriging).
Course content
- Why simulations: limitations of the use of kriging, importance of modeling heterogeneities for simulating reservoir production.
- General overview of simulation methods for categorical and continuous variables.
- Statistical and geostatistical analysis of the facies variability: reference surfaces, proportion curves. How to account for a lateral non stationarity.
- Variographic analysis of indicators.
- Conditional simulations of categorical variables: truncated gaussian method, indicator simulation, Boolean simulations. Extension of Truncated Gaussian approach to Plurigaussian, definition of transition schemes.
- Conditional simulations of continuous variables, such as properties: Turning Bands and Sequential Gaussian Simulations.
- Constraining of property simulations with facies.
This course may be scheduled for another date and/or location. Tailored courses may also be organized in your offices on demand focused on specific applications or algorithms, for example: velocity modeling and TDC, volumetrics and uncertainty analysis, seismic quality control and filtering, conditional simulations of continuous variables (SGS, Turing Bands) and/or facies (Plurigaussian, MPS), etc.
