EXPERIMENTAL STUDIES ON OPTIMIZATION OF AIRLIFT METHOD PARAMETERS USING SURFACTANTS AT OIL FIELDS

 

Annotation. This paper presents the results of comprehensive experimental studies on intensifying reservoir fluid inflow using the airlift method with surfactant addition in oil fields characterized by abnormally low reservoir pressures. The influence of surfactant concentration, injector submergence depth, and operating parameters of the gas-liquid flow on lifting efficiency was investigated. It is demonstrated that introducing an optimal surfactant dosage leads to a stable reduction in interfacial tension and emulsion viscosity, enhances gas dispersion, lowers the critical gas content velocity, and consequently reduces the required gas injection rate while maintaining the target production rate. Energy and economic performance indicators were evaluated, confirming that the optimal surfactant concentration yields the highest incremental oil production without significant increase in operational costs or adverse effects on subsequent product treatment and preparation. Furthermore, the effect of injector setting depth on the hydrostatic column and operational stability was analyzed; parameter ranges ensuring maximum efficiency were identified. The results obtained can be used to develop standardized procedures for surfactant-enhanced airlift operations in low-energy reservoir conditions.

Keywords: oil production, production optimization, surfactants, dependency plots, airlift method.
