Direct Hydraulics downhole control system, a
component of SmartWell® intelligent completion systems, uses direct hydraulic control lines from the surface to remotely
actuate downhole flow control devices such as interval control valves (ICVs).
The Direct Hydraulics system utilizes two hydraulic lines, one each for the open and close functions, connected directly to the device that is to be controlled. When networking multiple devices, a common close line can be used to minimize the number of lines needed.
