High-Pressure Drilling Riser (HPDR)
Oil States has been supplying high-pressure drilling risers based on our Merlin™ connector for over 40 years. We currently have 50+ installations around the world. Our system allows a subsea well to be drilled from a jack-up in 5K, 10K and 15K applications, offering significant savings over a semi or floating MODU.
Key Features
- Fast makeup and slimline connections keep weight to a minimum.
- Non-rotational connections allow the use of flexible control lines.
- Through-rotary solutions available dependent on size.
- Rental options available to reduce inventory after project.
Applications
- Jack-up subsea exploration / production wells
- Intervention from a jack-up
- Subsea abandonment
