| Summary: | Offshore field development projects are significantly different from onshore projects. Offshore operations include many difficulties, such as the specific technology for the operation and construction of wells, and the high cost of technical means. One of the most popular offshore field development projects is the Yu. Korchagin field. Various types of non-stationary flooding are actively and effectively used in this project, which are equipped with inflow control devices, among which passive and autonomous inflow control devices are distinguished. In the early 2010s, during the first drilling of the Neokomsko-Volzhskaya deposit, slit filters were used on wells, and later they began to use counter-pressure filters with the installation of sliding couplings. In multi-barrel wells, multi-position couplings are used to regulate the operation of each barrel. The introduction of some technologies in the conditions of extended horizontal boreholes of the Yu. Korchagin field had limited possibilities for launching equipment due to the complex trajectory of the well. The most urgent problems of modern oil and gas production are the completeness and efficiency of fluid extraction, achieving a uniform inflow profile, limiting and isolating gas and water breakthroughs. Inflow control systems, including and "intelligent" ones allow to minimize the flooding of wells, and the descent into the pumping and compressor pipes of the in-line electric centrifugal pump in case of failure of the standard pump will avoid the suspension of drilling operations. The purpose of the work is to analyze the application of the latest technological solutions at the Yu. Korchagin field in the waters of the Northern Caspian Sea.
