By the end of this training course, participants will learn to:

• To understand geostatistical methods.
• To apply geostatistical models to evaluate the data.
• To understand the concepts of Kriging and cokriging and how these are used in data analysis.
• To develop a conceptual geological model ahead of a static model building.
• To develop a sound structural model using regional data applied down to the model scale.
• To develop and test a stratigraphic model.
• To be able to develop a facies model and how to test this against analogs.
• To be able to determine petrophysical and property models.
• To know how to generate an accurate 3D static model by integrating all the above.
• How to integrate with reservoir engineer to match simulation data.

The course will not only be presented by showing and interpreting the material in detail, but also the

participants will work together using real data to apply all the workflow and to project their previous

knowledge and experience onto the course, they are also encouraged to bring their own data so that real

working examples can be reviewed and interpreted.
