Oil and Gas
Business Impact: Participants will develop the skills to add value by accurately assessing recoverable volumes, enhancing hydrocarbon recovery, and developing more robust reservoir simulation models.
This course aims to provide the practicing reservoir engineer with a range of analysis techniques and tools relevant to contemporary field development trends. Fundamental concepts will be discussed to ensure a solid foundation for understanding the applicability and limitations of the techniques presented. The learning will be supported and reinforced by examples and exercises throughout the course.
Duration and Training Method
This is a classroom or virtual classroom course comprising a mixture of lectures, worked examples, and practical exercises. A scientific calculator or laptop computer my be required.
