A fluid separation apparatus includes a hydrocyclone () having an orifice () therein, a housing () disposed in the hydrocyclone and having a bore (), a piston () disposed in the bore () of the housing (), and a first annular seal () disposed between the housing () and the piston () and configured to restrict fluid communication between the housing () and the piston (), wherein the piston () includes a passage () extending through the piston () and having a pin () coupled to a first end () of the piston, the piston () being actuatable to move between a first position () where the pin () is clear of the orifice () of the hydrocyclone, and a second position where the pin () is disposed in the orifice (), wherein, the piston () is configured such that as the piston is actuated from the first position to the second position, fluid is permitted to flow into the passage () of the piston () from the bore () of the housing ().

Fluid separation apparatus and system

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.

Fluid treatment system, a fluid processing apparatus and method of treating a mixture

A system and method for extracting oil from a fluid mixture includes a separation vessel having an internal chamber that extends to a chamber elevation, an inlet port, a water outlet port, and an oil outlet port. A liquid storage tank has an inlet port, an upper outlet port located at an upper outlet elevation, and a lower outlet port. A first conduit system interconnects the separation vessel's water outlet port and the tank's inlet port and has a top conduit segment at the upper outlet elevation. A second conduit system interconnects the first conduit system and the tank's inlet port. The second conduit system intersects the first conduit system below the upper outlet elevation and above the chamber elevation. A pump may be employed to transfer fluid from the upper outlet port back to the separation vessel.

Apparatus, system, and method for separating oil from a fluid mixture

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.

Apparatus, systems, and methods for downhole fluid filtration

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.

Wellbore desanding system

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.

Fluid treatment system, a fluid processing apparatus and a method of treating a mixture

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.

Separator system and related methods

A cyclone apparatus for separating a mixture containing at least one fluid and a further constituent based on the densities of the mixture constituents. The apparatus includes a first hollow pressure vessel having an overflow plate positioned at an overflow end of the first hollow pressure vessel and an end plate for sealing the overflow plate. The cyclone apparatus also comprises an underflow plate positioned at an under-flow end of the first hollow pressure vessel and a hollow pressure vessel with one end being sealed against the under-flow plate and another end being closed. The overflow plate and the end plate are shaped such that when they are brought together they form separate adjacent overflow compartments between them. The underflow plate and the second hollow pressure vessel are shaped such that when they are brought together they form separate adjacent under-flow compartments between them which correspond to the overflow compartments.
