Abstract [en]

In this Master Thesis jet pumps have been reviewed. Jet pumps are considered as a higher volume artificial lift method and operates by passing a high-pressure fluid jet through a venturi system. Cunningham's equations on jet pumps have been chosen to present the jet pump fluid mechanics. Factors impacting the jet pump performance have been investigated through a verified model. The performance of Prosper has been compared to Cunningham's model. A self-built model has been developed to calculate a well with a jet pump installed. An optimization has been performed on selected values to find the optimum combination of these. Jet pump performance and efficiency is dependent on several factors, such as: loss coefficients, densities, geometrical configurations, depth location, injection rate and pressure. These factors influence on performance have been studied. A comparison of Prosper's jet pump model with Cunningham's showed a discrepancy which was believed to be related to the jet pump implementation in Prosper. A self-built model was implemented to calculate a jet pump installed well. Some parameters were varied to investigate changes in production. Based on these results an optimization was suggested. By installing a jet pump the optimum results showed a 47% increase for the optimized pump compared with the well without jet pump installed.
