Halliburton developed the SmartPlex downhole completion system to selectively engage intelligent completion internal control valves.

“The SmartPlex system is about minimising control lines while increasing zonal control” in dry- tree applications, says Elias Garcia, Halliburton’s global technical advisor for flow control. He sees the system as particularly useful for mature fields, where water production may be a concern, and extended-reach wells, where there are often many zones to stimulate.
