COURSE DESCRIPTION: Gas-lift is one of the predominant forms of artificial lift used for lifting liquids from conventional, unconventional, onshore and offshore assets. Gas-lift and its variations – annular lift, tubular lift, plunger assisted gas lift, intermittent lift, gas-assisted plunger lift and chamber lift – allow life of well lift-possibilities when selected and applied properly. In unconventional wells, production phases and volumes vary quickly and significantly that requires non-traditional approach for selection, transition, surveillance and trouble shooting. This course is designed to give trainees thorough understanding of how unconventional production differs and what steps an operator can take to apply right sized and right form of gas lift technique to maximize profitability.

The course covers main components, application envelope, relative strengths and weaknesses of gas-lift and its different forms like intermittent lift, gas-assisted plunger lift. Trainees solve examples and class problems throughout the course. Animations and videos reinforce the concepts under discussion. A unique feature of this course is discussion on digital oil field and machine learning applications in gas-lift optimization.

Option: Client’s real-time system-based workflows and examples can be incorporated in the class discussions. Requires two-days of consulting and access to the client system at least 4 weeks before the class.

LEARNING OUTCOMES:

• Understand the fundamental theories and procedures related to Gas-Lift operations.
• Easily recognize the different components of the gas-lift system and their basic structural and operational features.
• Be able to select an appropriate gas lift configuration for different life stages of an unconventional well.
• Recent advances in real-time approaches to the production monitoring and lift management
