Key words: expandable profile liner, flow control valves, pressure gauges, temperature sensors, bottomhole pressure profile, production rates and watercut of individual intervals.

The paper presents the results of field tests of equipment intended to separate a horizontal wellbore into intervals, and surface-controllable valves to determine water-producing intervals and shutting-in thereof without interrupting the well production process.
