Below-Packer Vent Device
The Below-Packer Vent Device (BPVD) was developed for use with the Annulus-Pressure Crossover Assembly (APCA). Surface pressure applied to the annulus is transmitted through the APCA to a closed chamber below the BPVD and above a pressure-responsive firing head. The BPVD can be set to work before or after the perforating assembly is detonated.
Benefits
- Does not require tubing hydrostatic pressure to operate
- Can operate in highly deviated wells
- Can be used in wells with low formation pressure
- Eliminates nitrogen requirements
- Allows maximum underbalance
- Is compatible with several types of firing heads
- Features reliable and very accurate pressure response
