    摘要: Managing hydrates in a subsea includes a host production facility, a production cluster comprising one or more producers, a water injection cluster comprising one or more water injectors, a water injection line, and a single production line for directing production fluid from the one or more producers to the host production facility. The methods comprise placing a pig in the subsea production system, shutting in production from the producers, and injecting a displacement fluid into the subsea production system in order to displace the hydrate inhibitor and any remaining production fluids in the production flowline and to further move the pig through the production flowline. The method may also include further injecting displacement fluid into the subsea production system in order to displace the hydrate inhibitor and pig through the single production line and to the host production facility.

    摘要: A centrifugal method and apparatus capable of separating a fluid stream composed of a plurality of components with differing specific gravities. The stream contemplated for separation is that of a producing oil well with components of oil, water, natural gas, and particulates. The method and apparatus use centrifugal forces to separate the gaseous, solid, and liquid components from each other. After separation is completed, detector and sensor arrangements are used to maintain liquid levels in the separator and to control the removal of the individual separated fluids from the apparatus.

    摘要: A Vertical Annular Separation and Pumping System (VASPS) utilizing an isolation baffle to replace a standard pump shroud associated with an electrical submersible pump. The isolation baffle may be a one piece plate positioned so as to direct produced wellbore liquids around the electrical submersible pump motor to provide a cooling medium to prevent overheating and early failure of the electrical submersible pump.
