Course description

The course will give an overview of different simulation approaches and their strengths and weaknesses.  Some of the major applications of reservoir simulation will be illustrated through recent case histories studied by the instructor or published in the recent literature.


This course is designed for experienced reservoir engineers.  Attendees should possess basic skills in reservoir engineering and reservoir simulation, and have some experience in the use of commercial reservoir simulators.
