  • Patent number: 9885228
    Abstract: A fluid production system for downhole fluid purification includes a filtering assembly to be positioned within a wellbore. The filtering assembly has a fluid filter and a first pump closely-coupled to the filter. In addition, the system includes an extension shaft extending from the first pump to a source of rotational power positioned adjacent the surface of the earth.

  • Patent number: 9816359
    Abstract: The invention relates to system and method for desanding an oil well that includes a fluidizing device (TORE), connected to a downhole pump that connects to a production tubing such that a supply duct is connected to the discharge of the pump and a discharge duct is connected to the suction of the pump. Embodiments include a pressure balance transition device between the TORE and the pump and/or a flow splitting device in the production tubing after the discharge of the pump. Other embodiments relate to a system and method for desanding an oil well in which a fluidizing unit is connected to a pump such that the supply duct is connected to an opening in the pump body or pump rotor and a discharge duct is connected to the suction of the pump. If connected to the rotor, the supply duct is integral to the pump rotor.

  • Patent number: 9724707
    Abstract: A fluid treatment system, a fluid processing apparatus and a method of treating a mixture are provided in which a separator has two outlets for different components of mixed fluid. A conduit connecting one of the outlets of the separator to the inlet of the separator is provided to recycle fluid from an outlet of the separator back to the inlet and a pump at the inlet of the separator regulates the fluid flow through the separator at a constant rate. As a result, the flow rate through the separator is increased, which increases the separation efficiency of the separation system. The conduit also functions as a bypass line should the flow of fluid be obstructed through the separator. The conduit may preferably be operated in conjunction with an energy harvester.

  • Patent number: 8932472
    Abstract: A separator system and method are provided in which the separator has two outlets for different components of mixed fluid. An energy harvester is provided on one of the outlets, wherein harvested energy is transferred to a pump located on an inlet of the separator. As a result, the differential pressure across the separator is increased.

  • Publication number: 20130319952
    Abstract: A method of controlling a hydrocyclone system for separating a fluid mixture wherein the system includes a separator vessel for receiving the fluid mixture and performing a primary separation of the more dense and the less dense fluid phase thereby forming an interface within the separator, and a hydrocyclone apparatus having a first and second hydrocyclone compartments to separate the phases. The method includes alternating the flow rate through the hydrocyclone apparatus, alternating the interface or fluid mixture level in the separator vessel between a first level and a second level; and alternating the second hydrocyclone compartment between an open state in flow communication with the first hydrocyclone compartment and a closed state in isolation from the first compartment.
