3D Static Reservoir Structure and Property Modelling


Why to Choose this Training Course?




The main objective of this course is to provide a comprehensive understanding of static reservoir



modelling and reliable reservoir models- which is used to predict oil production- investigate



various production scenarios and eventually help decision makers to optimize field development.



The more data-consistent the model- the sounder the predictions. Thus- the key point is the



integration of all available data into reservoir models for field development strategies and how to



maximize recoverable hydrocarbon.




What are the Goals?



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



ï‚· To understand geostatistical methods.



ï‚· To apply geostatistical models to evaluate the data.



ï‚· To understand the concepts of kriging and cokriging and how these are used in data analysis.



ï‚· To develop a conceptual geological model ahead of a static model building.



ï‚· To develop a sound structural model using regional data applied down to the model scale.



ï‚· To develop and test a stratigraphic model.



ï‚· To be able to develop a facies model and how to test this against analogues.



ï‚· To be able to determine a petrophysical and property models.



ï‚· To be able to build a fracture model based on seismic and well data.



ï‚· To know how integrate FMI fracture data to be distributed in 3D model.



ï‚· To know IFM & DFN modelling.



ï‚· To know how to generate an accurate 3D static model by integrating all the above.



ï‚· How to integrate with reservoir engineer to match simulation data.




How will this Training Course be presented?




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



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



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



working examples can be reviewed and interpreted.




Who is this Training Course for?



This course is designed for all Oil Industry Technical Professionals- which will cover from fundamental



theoretical background to high-level real work information- techniques and workshop.



This training course is suitable to a wide range of professionals but will be greatly beneficial for:



ï‚· Geo-Modelers- Petrophysicists- Seismic Interpreters- Development Geologists- Reservoir



Engineers- Well site geologists- Technical Support Personnel- Team Leaders & Managers.



Organizational Impact



Organization will have a well-trained geo-modeler who can run static models using petrel software for



field development and enhance hydrocarbon recovery.



Personal Impact



Upon completion of the course- participants will be able to understand complete work flow for



reservoir property modelling and fracture modelling workflow in the base of conceptual geological



model and integrate all available data set
