Well Control Unit

The WCU controls and operates the pressure control equipment, such as Grease injector head, Wiper, Stuffing box, Tool catcher, DHSV, Master valve and chemical injection. There is also a built-in pressure test pump used for rig-up leak test. A local control panel with explosion-proof LCD monitor displays all parameters and trend curves, including the well pressure and annulus pressure.

Well Control Unit

Enable to set automatic diff. pressure between the well pressure and Grease Injection Head pressure to reduce the risk of losing well control (leak in GIH, sealing against well pressure).
.
The hydraulic hoses are installed on hydraulically driven reels, controlled from a local control panel.  The WCU is built to achieve optimal access for service and maintenance. Visual inspection and filter changes can be carried out fast and easily.
