COURSE OVERVIEW:

Well Inflow Performance Relationships (IPR) and Vertical Lift Performance (VLP) Fundamentals is the definitive course for understanding the "Engine" of the production system. Every barrel of oil produced is a result of the balance between the reservoir's ability to deliver fluid (IPR) and the wellbore's ability to carry that fluid to the surface (VLP). This course provides engineers with the mathematical and analytical framework to perform Nodal Analysis, allowing them to optimize drawdown and maximize production rates.

The scope of this training includes the detailed study of Darcy’s Law, Vogel’s Equation, and the concept of "Skin" as it relates to inflow efficiency. Participants will explore the factors that restrict flow, such as formation damage, turbulence, and partial penetration. On the outflow side, the curriculum covers the hydraulics of multiphase flow, teaching attendees how to calculate pressure drops in the tubing and identify the point where a well will naturally "load up" with liquids and cease to flow.

Coverage also includes the use of Nodal Analysis software to model various "what-if" scenarios. Attendees will learn how to predict the impact of changing reservoir pressures, increasing water cuts, or upgrading tubing sizes on the well's production profile. By mastering the interaction between IPR and VLP, participants will be able to identify underperforming wells, justify artificial lift installations, and design completions that are perfectly tuned to the reservoir’s potential.

COURSE OBJECTIVES:

After completion of this course, the participants will be able to:

• Explain the physical principles governing fluid flow in the reservoir and tubing.
• Construct and interpret IPR curves for oil, gas, and multiphase wells.
• Calculate the Productivity Index (PI) and analyze its decline over time.
• Quantify the impact of "Skin" on inflow performance and identify its components.
• Apply Vogel’s and Fetkovich equations for saturated reservoir conditions.
• Construct Vertical Lift Performance (VLP) curves for various tubing sizes.
• Perform Nodal Analysis to find the natural operating point of a well.
• Predict the onset of "liquid loading" in gas wells and propose solutions.
• Evaluate the impact of surface backpressure on well deliverability.
• Select optimal tubing diameters to maximize production while preventing erosion.
• Use Nodal Analysis to justify and size artificial lift systems.
• Analyze the effect of water cut and GOR changes on the VLP curve.
• Troubleshoot well underperformance by identifying shifts in IPR or VLP.

TARGET AUDIENCE:

Production Engineers, Reservoir Engineers, Well Test Engineers, and Petroleum Engineering Students seeking a deep dive into Nodal Analysis.

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximise the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
