Abstract
An apparatus includes a seabed-disposed pump that includes an inlet to receive a fluid flow and an outlet. The apparatus includes a liquid retainer that is adapted to receive a fluid flow that is produced by a subsea well. The liquid retainer selectively retains and releases liquid from the fluid flow to regulate a gas volume fraction of the fluid flow that is received at the inlet of the pump.
Claims20
An apparatus comprising:
- a seabed-disposed pump comprising an inlet to receive a fluid flow and an outlet;
- and
- a liquid retainer adapted to:
- receive a fluid flow provided by a subsea well;
- and
- selectively retain and release liquid from the fluid flow provided by the subsea well to regulate a gas volume fraction of the fluid flow received at the inlet of the pump.
3 more elements
An apparatus comprising:
- a pump comprising an inlet and an outlet;
- a recirculation path coupled between the inlet and the outlet of the pump;
- and
- a flow splitter to receive a first flow and provide a flow to the inlet of the pump, the flow splitter comprising:
- a receptacle to receive the first flow and retain a predetermined volume of liquid to regulate a gas volume fraction at the inlet of the pump.
2 more elements
A method usable with a well, comprising:
- pumping production fluid from a subsea well to a surface platform;
- and
- storing and releasing liquid associated with the communication of the production flow to regulate a gas volume fraction of the fluid flow.
