Objective
Introduction (Subsea Layout and Gas Lift Arrangement)
Selection of the Artificial Lift Method Fluid Properties
Multiphase Simulation x Test Result
Lessons Learned
Conclusion and Recommendation
Some questions still rely on the ability of the gas-lift method to do a good job when applied to heavy oil wells, mainly under a deep water scenario.
The aim of the forward analysis was to evaluate the performance he continuous gas lift method applied to lift heavy oil at long distance satellite production wells in a low temperature deep water scenario. To compare predicted flow parameters against measured well production test.
