An Improved Gas-Lift Design and Analysis Software by Roger Stinson & Balraj Grewal Schlumberger Abstract The gas-lift design and analysis capabilities of the Baker Jardine (now part of Schlumberger) Pipesim software have been improved significantly. An innovative feature of the software is a feature that sizes ports and calibrates temperature for upper unloading valves based on unloading fluid rate and gas volume requirements. Other improvements allow gas-lift engineers to customize gas-lift designs by allowing the user to specify the design method to be used, set design biases and safety factors, and design bracketing spacing for future conditions or uncertain conditions. This flexibility allows gas- lift engineers from different backgrounds and experience to customize designs based on specific field conditions, and individual preferences and experience. Case studies will be presented based on application of this technology.
