Abstract
The invention provides well control system for a riser. The well control system comprises a riser assembly and at least one flow meter. The at least one flow meter is configured to be mounted on the riser.
Claims27
A well control system for a riser comprising:
- a riser assembly, comprising:
- an upper riser disconnect assembly located axially above a tension ring, between the tension ring and an upper end of the riser assembly;
- a managed pressure drilling manifold located above the upper riser disconnect assembly and the tension ring, the managed pressure drilling manifold comprising:
- at least one flow meter;
- at least one choke assembly;
- and
- a flow line fluidly connected to a riser bore above the upper riser disconnect assembly,
- wherein the at least one flow meter and the at least one choke assembly of the managed pressure drilling manifold are mounted on an outer surface of the riser assembly and supported by the riser assembly.

A method of measuring at least one parameter or property of drilling fluid in a subsea riser comprising:
- providing a well control system for the subsea riser, the well control system comprising:
- a riser assembly comprising a tension ring and an upper riser disconnect assembly located above the tension ring, between the tension ring and an upper end of the riser assembly;
- and
- a managed pressure drilling manifold located above the upper riser disconnect assembly and the tension ring, the managed pressure drilling manifold comprising:
- at least one flow meter;
- at least one choke assembly;
- and
- a flow line fluidly connected to a riser bore above the upper riser disconnect assembly,
- wherein the at least one flow meter and the at least one choke assembly of the managed pressure drilling manifold are mounted on an outer surface of the riser assembly and supported by the riser assembly;
- and
- measuring at least one parameter or at least one property of the drilling fluid in the riser bore.
