13-5/8" PCD 5000
The 13-5/8" PCD 5000 is a pressure control device designed to cap and seal return mud flow in managed pressure and underbalanced drilling operations. The control device uses the unique Siem WIS patented sealing solution, which provides safe, predictable and efficient sealing technology using non-rotating sealing elements.
The PCD 5000 complements the rig's BOP stack with a multi-seal barrier which seals of, and safely diverts, the flow from the annulus. The PCD 5000 body can handle pressures of up to 5000 psi and has a through bore of 13-5/8" when the bore protector is installed. The PCD 5000 acts as a multi-seal barrier system in operations such as:
- Managed Pressure Drilling (MPD)
- Under Balanced Drilling (UBD)
- Additional barrier above the rig BOP/Annular with continuous monitoring
The patented sealing solution provides real time seal condition monitoring which creates operational redundancy and predictability. The condition and performance of the sealing elements are monitored and logged at all times. Unlike many conventional RCD systems, the Siem WIS sealing element's pressure rating is not de-rated when the rpm increases.
Customer and operation specific
The PCD can be configured according to customer specific operational requirements. As a standard, the PCD comes with a 13-5/8" 5K API bottom flange. However, the bottom housing of the PCD is interchangeable and can be replaced by different x-overs and flow spools with customer-specified outlets to match stack-up interfaces and reduce stack height. A few examples of bottom housings:
The PCD 5000 has excellent capacity with a full dynamic pressure rating throughout the entire operating range from 0 to 150 rpm. Short excursions to 200 rpm are allowed.
The PCD 5000 system consist of:
- PCD 5000 unit
- Control container
- HMI work station
- Pressure distribution skid
- Lubrication and slop tank
- Pre-loaded seal cartridge and bore protector
- Running tool with operation-specific drill collars
