Aquaterra Energy gets low-pressure riser joints from Arc Energy

Offshore staff

EASTINGTON, UK – Arc Energy Resources has supplied two riser joints to Aquaterra Energy. The components are part of two low-pressure risers for an oil platform.

The finished risers were destined for a set of 20 wells being drilled in the North Sea off the coast of Norway. It is a new development for a low pressure section of pipes to deal with any drill fluids and shallow gas that they may encounter while drilling the first top-hole section of a well.

The component acts as a conduit for drilling fluids and equipment during the top hole and ensures that in the event of gas passing up through the well it can be contained and routed to the rig diverter where it can be vented to atmosphere.

The risers need to have a sealing ring groove in the end of the flange, which is inlaid with a hard, corrosion resistant Inconel 625 alloy.
