“…When it comes to dealing with pressure loss problems or taking on the challenges of producing heavy oil from oil wells, all three artificial lift technologies (continuous flow gas lift, intermittent flow gas lift, and electrical submersible pump) are competitive. The simulation tool PROSPER (Production and System Performance Analysis System) is effective in optimising gas lift operating parameters and predicting comparative well performance for each of the artificial lifts [ 9 ]. This tool is found to be extensively in use for studies related to gas lift design and to find out under what conditions the self-flowing state of a naturally flowing well can be sustained and which method of artificial lift would be feasible to produce in the future.…”
