Overview

This course utilizes the techniques for design and performance analysis of the production system starting from the formation up to the wellhead/separator. The topics include the production systems that integrate the flow of single-phase or two-phase fluids to wellbore and from wellbore bottom to wellhead/separator. This teaches various flow regimes and models to derive inflow performance relationships and vertical flow relationships, combination of which gives the well deliverability.

Course Objectives

• Identify the components of a complete production system and understand their functions, interrelationships, and effects on the performance of the system.
• Use production and test data to determine the inflow performances of oil and gas wells.
• Understand the basics of multiphase flow in pipes and use correlations to determine outflow performance of wells.
• Determine well performance by integrating inflow and outflow performance.
• Determine well performance with Electric Submersible Pump (ESP).

Learning Outcomes

• Use mathematics, science and engineering knowledge to study and understand production systems
• Predict inflow performance relationships (IPR), wellbore pressure profile and design vertical lift performance (VLP), including performance with ESP.
• Solve problems combining IPR and VLP.

Who Should Attend
• Engineers with 0-3 experience (Former PI graduates are not preferred as they already took this course).
• Engineers with non- Petroleum Engineering degree working as completion/ production operations engineers or reservoir engineers.
