Advanced Inflow Profiling Technologies

The paper describes the use advanced technologies for monitoring the inflow profile of production wells. The technologies are based both on the inclusion of the flow metering devices into the completion and on the installing of the flow metering devices into already working wells. The work was carried out to monitor the operation of production wells, finished with wire and mesh filters, including the multilateral wells. The inclusion of tracers into the completion was carried out to measure the inflow rate of oil and water, including to assess the productivity index of each interval or each well in the multilateral separately. After the wells are put into operation, sampling of the well fluid at the wellhead and regular analysis of the content of tracers allows determining the interval profile of oil and water inflow. The work was carried out at several dozen wells of the Russian, Okunevskoye, Vaneganskogo fields in 2016 - 2019 (work continues - scaling). The results of real-time flow profiling are shown, including studies of the productivity index of each interval as well as each well in multilateral wells.
