Streamline Modeling for Waterflooding

Program Objectives

This 5-day course presents streamline simulation fundamentals and builds upon basic understanding of waterflooding & finite difference simulation. The course covers an overview of how streamline simulators work including numerical methods and saturation solvers, however emphasis will be placed on practical use of the streamline simulator. Participants will learn where, when, and how to apply streamline simulation for a robust solution, and when the solution becomes numerically inaccurate and unstable. Flowstream will be used by students for waterflood optimization and understanding throughout the course. We will demonstrate advantages and disadvantages of streamline simulation compared to traditional finite-difference simulation and how to combine streamline visualization with finite difference simulation. In addition, students are encouraged to present case studies for their own fields for general discussion during the class.
