The authors of the article consider the current problem of improving the efficiency of oil preparation in fields with a high gas factor. The analysis of the problems associated with the associated petroleum gas (APG) utilization, which is released at the final stages of separation and is characterized by low pressure and high content of heavy hydrocarbons is presented. The article an effective solution, which involves the circulation of gas from the final stages of separation and its return to the beginning of the process chain, to the suction of the first-stage compressor is proposed. The advantages of this scheme are described in detail, including increased stability of the separation process, reduced losses of light hydrocarbons, improved environmental performance and increased yield of marketable oil. The options for implementing the circulation scheme are considered. It is emphasized that the implementation of the gas circulation scheme from the final stages of separation is a promising approach for improving the efficiency and environmental safety of prepared systems which allow decreasing the losses of valuable hydrocarbons, increasing the quantity of prepared oil and minimizing the impact on the environment.
