4 Jack-Up Rig HP Riser System Design Factors
In addition, as jack-up rig rates are typically lower than semi-subs, considering a HP riser system is a no-brainer for drilling, workover and
Understanding Offshore Risers: A Critical Component
Drilling Risers Used during drilling operations, these risers guide the drill string from the platform to the seabed and facilitate the return of drilling fluids.
Deepwater Riser | SpringerLink
Deepwater risers are one of the important facilities for deepwater oil & gas development and the link between subsea wellheads and a unit at sea surface. For the sake of

Marine Drilling Riser Systems (MDRS) | Oil States
The marine riser forms a continuation of the well bore from the top of the blowout preventer stack to the drilling vessel. The subsea well is drilled through the marine riser allowing the mud to
Marine Riser Systems and Subsea Blowout Preventers
A marine riser system provides a fluid conduit to and from the wellbore—that is, it extends the wellbore from the subsea BOP to the drilling rig. It also supports auxiliary lines, such as high
