The Nexus De-Booster is a stepped piston device that reduces the high wellbore pressures at the well monitoring port by 75%. Pressures are read on a remote pressure gauge or recorder. The pressure reduced by the 4:1 ratio is transmitted by hydraulic fluid to the gauge. De-Boosters are used to allow the use of lower pressure gauges to monitor wellbore pressure, and also provides a protection barrier of potentially dangerous wellbore fluids from the control lines.
- A special mounting bracket is supplied for mounting directly to the BOP body. A control line to connect into the pressure monitoring port is sold separately.
- Newer Nexus BOP’s come standard with De-Booster porting and mounting holes.
- Modifications can be made to older style BOP’s to have the porting and mounting holes added.
