Introduction to Reservoir Engineering for Non-Specialists

Introduction:

Reservoir Engineering is a discipline that encompasses principles of science and technology, as well as an understanding of hydrocarbon reservoir behavior. It is essential for assessing oil and gas reserves and for formulating improved recovery practices.

Detailed analysis of reservoir data, comprehension of reservoir responses to various conditions, and the implementation of best practices for surface management are critical. Without these, billions of barrels of recoverable oil and gas may remain untapped. Therefore, mastering reservoir engineering is vital for enhancing hydrocarbon resource recovery.

This course is designed for non-engineers and provides a fundamental understanding of hydrocarbon behavior in reservoirs and the recovery processes. It introduces participants to practical aspects of reservoir engineering and presents existing techniques used in the industry to solve reservoir challenges and enhance resource recovery.

Objectives:

Upon completing this reservoir engineering course, participants will be able to:

• Understand reservoir types, classification, properties, and other factors.
• Relate fundamental properties of reservoir rocks and fluids that influence PVT (Pressure, Volume, Temperature).
• Explain fluid movement in porous media.
• Define and describe reservoir volume based on fluid type and influencing phenomena.
• Understand the distribution of reservoir fluids within a fluid system.
