MPD Buffer Manifold

Route flow in a variety of advanced drilling systems without reconfiguring piping.

Render of Buffer Manifold
Description

The buffer manifold is designed to route flow without the need to reconfigure piping. The buffer manifold can be used as part of advanced drilling systems, either in a riser gas handling system or as part of a full managed pressure drilling (MPD) system, including pressurized mud cap drilling. NOV can provide a complete set of solutions to turn any rig into an MPD-Ready rig.
