COURSE OVERVIEW:

Gas lift remains one of the most versatile and widely used artificial lift methods in the global oil and gas industry, particularly in offshore and high volume environments. This course provides an in depth analysis of the mechanics of gas lift, focusing on the reduction of bottomhole flowing pressure through the injection of compressed gas into the production string. Participants will explore the transition from natural flow to artificial lift and learn how to determine the economic tipping point for gas lift implementation.

The curriculum covers the entire lifecycle of a gas lift system, from the initial design of the mandrel spacing and valve selection to the daily optimization of injection rates. Detailed instruction is provided on the physics of gas expansion and its effect on fluid density and flow regimes. The course emphasizes the importance of nodal analysis in predicting well behavior and ensuring that the selected gas lift equipment is capable of handling both current and future reservoir conditions.

Operational excellence is achieved through diligent troubleshooting and continuous monitoring. This course equips participants with the tools to diagnose common gas lift failures, such as valve bellows fatigue, multi pointing, and hydrate formation. Through the interpretation of downhole surveys and surface data, attendees will learn how to maximize the oil production rate while minimizing the gas lift ratio, thereby ensuring the highest possible efficiency for the available compression capacity.

COURSE OBJECTIVES:

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

• Describe the fundamental principles of gas lift and its effect on the vertical lift performance.
• Design a gas lift valve string using industry standard spacing techniques.
• Select appropriate valve types and orifice sizes for specific well conditions.
• Optimize the gas injection rate to maximize the oil production versus gas cost.
• Interpret two pen recorder charts and surface data to monitor well health.
• Troubleshoot common gas lift issues including tubing leaks and valve malfunctions.
• Differentiate between continuous and intermittent gas lift applications.
• Perform nodal analysis to evaluate the interaction between the reservoir and the lift system.
• Diagnose instability and heading issues in gas lift wells.
• Manage gas lift operations in wells with high solids or scale potential.
• Evaluate the impact of surface backpressure on gas lift efficiency.
• Design unloading sequences to safely initiate production in killed wells.
• Formulate a gas lift surveillance plan using modern digital oilfield tools.

TARGET AUDIENCE:

This course is designed for Production Engineers, Reservoir Engineers, Completion Engineers, and Operations Staff responsible for the design, surveillance, and optimization of gas lift systems.

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.
