Abstract The paper presents a methodology for optimizing Gas lift wells, aimed at enhancing the gas injection pressure and consequently deepening the gas injection point to improve the gas lift performance. An in-depth evaluation is performed to optimize the gas lift method, employing both simulation software and in-house developed gas lift tools. The process involves the strategic installation of Side Pocket Mandrels (SPMs) equipped with Injection Pressure Operated (IPO) valves and Venturi valves at specific depths to optimize gas injection points. The analysis also looked the impact of installation of Pressure Control Valves (PCVs) in the Gas lift pipe line networks, which in computer simulations showed potential to increase gas injection pressure. The increase in pressure enables the optimization of the gas lift wells, thereby improving well performance. The comprehensive nodal analysis and calibration pressures were applied to fine-tune the gas lift designs, considering the individual characteristics of expected targeted wells. In the simulated scenarios, the newly evaluated methodology improves gas lift wells’ efficiency by 18%. The PCV installation and subsequent adjustments in injection pressure enables the targeting of deeper gas lift injection point, optimizing the gas lift performance and enhancing drawdown and overall well productivity. The custom-developed real-time gas lift monitoring system was pivotal in continuous performance evaluation, allowing for immediate detection and resolution of issues such as gas re-circulation and valve leaks. This paper introduces innovative techniques and methodologies in gas lift optimization, particularly emphasizing the development and utilization of a proprietary real-time monitoring system for gas lift operations. This system represents a significant advancement in the field, enabling real-time diagnostics, troubleshooting and optimization across multiple wells. The integration of gas lift rig-less technologies is also proposed to enhance the economic viability and operational efficiency of gas lift systems. This innovation marks a significant advancement in artificial lift methods, presenting a more efficient and integrated approach to Gas Lift performance monitoring.
