On Thursday, August 21, 2025, the College of Engineering at the University of Baghdad hosted a public discussion of the master’s thesis submitted by student Hayder Hulail Saleem in the Department of Petroleum Engineering. His thesis was entitled:
“Design of Gas Lift System in Ahdab Oil Field.”
The discussion was held in the discussion hall of the Department of Petroleum Engineering. The committee consisted of the professors listed below:
- Prof. Dr. Ayad A. Alhaleem – University of Baghdad / Department of Petroleum Engineering – Chairman
- Asst. Prof. Dr. Usama Alameedy – University of Baghdad / Department of Petroleum Engineering – Member
- Dr. Hairash N. Hamarash – Ministry of Oil / North Oil Company – Member
- Asst. Prof. Dr. Ghanim M. Farman – University of Baghdad / Department of Petroleum Engineering – Member and Supervisor
The study aims to design an optimal gas lift system that achieves the highest possible productivity for wells experiencing declining production and to improve production for other wells. It also aims to determine the system’s response to future changes in operating conditions, such as declining reservoir pressure or increased water cut. The wells under study are five horizontal wells, three located in Mishrif Formation and two in Rumaila Formation. Pipesim software was used to complete this study.
After designing the gas lift system, it was found that the optimal injection rate and injection pressure for the wells located in Mishrif Formation are 1 mmscf/d and 1700 psi. For the wells located in Rumaila Formation, the optimal injection rate and injection pressure are 1.25 mmscf/d and 2000 psi. The gas lift system designed for the five wells achieved significant production increases of 50%, 46%, 380%, 185%, and 116%. The gas lift system also demonstrated high flexibility and efficiency in addressing future changes that could impact production, such as increased water cut or decreased reservoir pressure. This was achieved through a hypothetical study simulating these changes. The system’s success was evident despite the assumption that the water cut would reach 90%.
