Course description
Chemical Enhanced Oil Recovery Fundamentals - EORC
This course gives an overview of oil recovery processes that involve the use of polymer, surfactant, alkali, gel, and a combination of them. Furthermore, it reviews reservoir engineering fundamentals and describes the principles for a variety of chemical enhanced oil recovery processes. The current status of these technologies is discussed and guidelines are presented for initial screening for each process corresponding to particular field conditions. Examples of laboratory and field performances are presented. Simulation exercises are used for each process. One personal computer is provided, at additional cost, for each two participants.
Suitability - Who should attend?
Engineers, geoscientists, management personnel or other technical personnel with at least a B.S. degree and some experience in reservoir engineering. The course benefits individuals who are responsible for the design, implementation and management of chemical EOR projects. However, the contents of this course are also beneficial for other technical personnel involved in numerical simulation studies, screening, and planning of EOR applications. This course may interest new recruits as well as experienced professionals who want to gain a better understanding of the concepts, practices, benefits, and limitations of chemical EOR methods.

"Instructor was a living encyclopedia! So knowledgeable and willing to help and answer questions."
"This class was a perfect blend of theory, lab tests and field examples (my favorite). Could not be improved upon - perfect amount of time spent on each area."
"I really enjoyed the overall summaries about the different types of chemical EOR, field examples and all of Dr. Delshad's first hand experience and advice."
