ABSTRACT
One artificial lift method that is commonly used to increase oil output is gas lift. Oil wells typically produce based on the energy of solution gas and reservoir pressure, which decreases with continued production. As a result, many oil wells lose their ability to raise oil to the surface after a set amount of production. In order to maintain output, a gas lift must be installed. This device uses gas injections through the annulus to lower the average fluid density in the tube. The goal of this study is to extract as much oil as possible at the best injected gas rate from an oil field in Delta. The six key variables that maximize the gas lift system have been identified. They are wellhead pressure, reservoir pressure, water cut, tubing d iameters, casing pressure, and depth of injection, which all of the variables could influence the oil production rate. We considered one of these factors, water cut, in this investigation. PROSPER has carried out the software analysis. We took a well from the Niger Delta Field for our data on the oil field and well configuration. The well network in this project has been examined with a minimum Pwf of 50 psi plus the bubble point pressure. The amount of injection gas, which aims to inject varying amounts of gas and determines the maximum oil production rate, is the primary variable. The study's goal is to maximize the field's oil output through gas lift optimization. to modify the sensitivity analysis and optimal outcomes.
