OVERVIEW
The Training focuses on a number of key topics not normally discussed in reservoir simulation courses or well understood even by experienced practitioners of reservoir simulation.
The Training discussion is supplemented by the frequent use of specially prepared spreadsheets to illustrate the application of key concepts and methodologies using actual field examples. Course participants will be able to download the spreadsheets for future work-related and self-study purposes.
BY ATTENDING THIS TRAINING, YOU WILL:
- Know how to assess and mitigate the adverse effects of numerical dispersion, and grid orientation effects on simulator predicted field performance.
- Understand models used to estimate relative permeabilities, residual saturation and capillary pressures and how to effectively use these in cases where core measured data is limited or absent.
- Know how to effectively and efficiently use up-scaling and pseudo-functions to improve predicted reservoir performance.
- Understand grid selection options and know how to select the best grid for a specific simulation study.
- Know how to model gas condensate reservoirs and condensate blockage effectively.
- Understand how to design and run full-field simulation studies optimally.
