GAS LIFT DESIGN AND OPTIMIZATION
COURSE OVERVIEW & LEARNING OUTCOMES
This course focuses on gas-lift design using hands- on graphical design methods (based on API RP 11V6/19GB and API Gas -lift manual), gas lift surface facilities, surveillance, automation, trouble- shooting and optimization for better economics. Excel spreadsheet programs will be used in class to buttress theory including gas lift performance models. Emphasis is also placed on surveillance as the starting point for all activities on the wells. Use of dynamic models will be demonstrated in class to show how automation can be used to assist with production surveillance.
