The technology for monitoring the inflow with high accuracy in determining the flow rate, water cut and gas showings was visualized.

The assembly is equipped with controlled ports and filters able to close in the event of a gas or water breakthrough. In the case of launching injection wells, it determines the percentage of water cut within a particular section. A Geosplit behind-the-casing marker cassette is applied in the assembly. The marker tape consists of a polymer-coated material with quantum markers that allow marking of each section with unique codes.
