The hydrocarbon production process is characterized by operational features that are unique for each region. An extensive list of physical and chemical parameters of the fluid, different depths of bedding, many in-situ complicating factors of production, different climatic conditions set the vector for the development of the oil and gas industry for each region. In order to maintain production at the current level, oil companies are forced to seek new horizons for drilling wells and carry out various geological and technical measures to intensify oil production. In the same time these measures contribute to a significant increase in the volume of produced formation water. This fact has a direct, negative impact on the existing ground infrastructure (oil treatment and gas compression facilities, reservoir pressure maintenance, power supply, etc.) and engineering networks. One of the most effective methods to reduce operating costs at mature oil production assets is reengineering of onshore infrastructure facilities. Reengineering measures allow to optimize the production process, to unload existing on-site facilities, the collection system, to reduce hydraulic losses for oil transportation and pumping of produced water. The development of a reengineering program is carried out taking into account the assessment of the prospects and the selection of the most optimal measures, using scenario planning. As part of the analysis of the impact on the production process, 4 main directions of reengineering on a mature asset have been identified, which are the foundation of the production process in terms of ground infrastructure. The authors propose a solution that will contribute to ensuring the efficiency of oil and gas production processes, extend the life cycle of mature oil and gas production assets of the Russian Federation and their economic profitability.
