Annotation:

At the moment, most of the oil fields are at the final stage of development or are already close to it. Achieving the highest possible and economically cost-effective oil recovery coefficient remains a priority task when designing the development of oil fields. The existing practice proves the fact that simultaneous separate operation of several layers by one well is one of the technical solutions that reduce capital and operating costs, increase the efficiency of the development of multi-layer deposits.

The information about installations for simultaneous and separate operations has been known for quite a long time, but due to the low reliability of the equipment, the complexity of manufacturing and repairing wells has not found wide application. At present, the technique and technology of reservoirs simultaneous separate operation has moved to a new level. Installations for simultaneous and separate operation have become not only a tool for obtaining additional oil production, but also an element of the development system for multi-layer deposits by combining operational facilities, regulating the process of selecting oil reserves separately for each facility. The article provides examples of design solutions for the development of multi-layer deposits using the technology of simultaneous separate operation of layers, which allowed increasing the efficiency of development due to the full use of the already drilled well stock.
