High-Pressure Drilling Riser (HPDR)

HPDR Riser SystemOil States has been supplying high-pressure drilling risers based on our Merlin™ connector for over 30 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.
