Purpose: The study aims to investigate the hydraulic efficiency of gas gathering pipelines of the Yuliivskyi oil and gas condensate production facility (OGCPF). Identify the main factors that lead to a decrease in the hydraulic efficiency of gas gathering pipelines. Design/methodology/approach: The modes of operation of gas gathering pipelines were studied experimentally at gas treatment units. Calculations determined the volume of liquid contaminants in the internal cavity of gas gathering pipelines. Industrial studies were conducted to measure the volume of transported gas and liquid contaminants entering the flow. A comparison of the obtained values makes it possible to assess objectively the presence of liquid contaminants in the internal cavity of gas gathering pipelines. Findings: Based on the results of studies of the gas gathering pipelines' hydraulic efficiency, it was found that the volume of liquid contamination determined by calculations is less than that determined by the results of industrial studies. The main factors that adversely affect the hydraulic efficiency of gas gathering pipelines have been identified. Timely monitoring of these main factors will help prevent a decrease in the hydraulic efficiency of gathering pipelines and a decrease in the volume of transported gas. Implementing a system for monitoring the efficiency of gas gathering pipelines will allow timely measures to be taken and prevent a decrease in gas transportation. Research limitations/implications: To improve the efficiency of gas gathering pipeline operation, it is advisable to introduce new approaches to timely prediction of complications, particularly developing and implementing various control systems. Practical implications: The performed studies make it possible to objectively assess the reasons for the decrease in the hydraulic efficiency coefficient of gas gathering pipelines, which will make it possible to predict it to prevent a decrease in the volume of transported gas. Originality/value: It is proposed to use a system for monitoring the efficiency of gas gathering pipelines. Applying this approach generally ensures the efficiency of analysing the state of gas gathering pipelines and timely action.
