摘要： The invention generally concerns an arrangement of a low volume submersible pump connected to a downhole gravity type oil-water separator. The low volume submersible pump is electrically powered using a flexible electrical cable that connects between the pump and electric power located at the ground surface. The low volume submersible pump is typically a positive displacement pump such as a piston pump or a hydraulically driven diaphragm pump but could be a centrifugal pump if the volumes produced are compatible with this method. The separator is located above or below the pump and is defined by an enclosed, pressure-tight volume created by a separate container or by two or three downhole packers. Located in the separator is a control valve that regulates the flow of oil and water from the separator to discharge tubes connected to the surface or to additional downhole apparatus.

摘要： A method and system for producing a mixed gas-oil stream through a wellbore wherein at least a portion of the gas is separated from the stream downhole and is compressed (e.g. using a SPARC) before both the compressed gas and the remainder of the stream is brought to the surface through separate flowpaths. The system includes a string of tubing which provides the flowpath for the remainder of the stream while the annulus, formed between the tubing string and the wellbore provides the flowpath for the compressed gas.

摘要： A gas-liquid separator positionable down hole in a well bore includes an external tube having an external tube interior and an internal tube having an internal tube interior. The internal tube is positioned in the external tube interior to form an internal annulus defining a gas flowpath and the internal tube interior defines a reduced-gas fluid flowpath. A plate at least partially encircles the external tube to form a curved flow channel, which defines a produced fluid mixture flowpath. A first internal annulus opening is provided in the external tube, which defines a gas inlet port. An internal tube interior opening is provided in the internal tube, which defines a reduced-gas fluid inlet port. A produced fluid mixture is conveyed through the flow channel, which spins the produced fluid mixture about the external tube. At least a portion of a gas in the produced fluid mixture is separated from the liquid in response to spinning, thereby producing a separated free gas which enters the gas flowpath via the gas inlet port and a reduced-gas fluid which enters the reduced-gas fluid flowpath via the reduced gas-fluid inlet port.

摘要： A system for removing solid particulates from a production fluid. The system includes a solid separator to remove the solid particulates from the production fluid to reduce pump component wear. The system is disposed in a wellbore such that wellbore fluids are drawn into the solids separator before entering the submersible pump. Solid particulates are separated from the fluid that flows through the solids separator before entering the submersible pump. The solid particulates are routed past the submersible pump. The solid particulates may be reinjected into the fluid discharged from the pump.

摘要： A method of extracting liquid hydrocarbons from geological formations having a reduced or low liquid hydrocarbon flow rate utilizing a wellbore extending downwardly from the surface of the ground into the geological zone of interest. The method includes the steps of first creating at least one downhole reservoir through enlarging a portion of the wellbore. The downhole reservoir is made substantially larger than the wellbore and formed so as to hold a desired amount of effluent, which includes liquid hydrocarbons, based upon approximated flow rates of effluent from the geological zone of interest. Effluent is allowed to accumulate in the downhole reservoir for a desired length of time until it reaches a desired level. Finally, the effluent is evacuated from the downhole reservoir through the use of a pump.

摘要： An intake assembly for a well pump restricts gas entry into the pump when the pump is located in a horizontal section of the well bore. The restrictor is located within a tubular intake housing. The intake housing has apertures for receiving the flow of well fluid. The apertures are spaced circumferentially around the housing. Once installed in the well, some of the apertures will be at higher elevations than others. The restrictor partially blocks at least one of the higher elevation apertures and opens at least one of the lower elevation apertures. The gas will be at the higher elevations, thus it is restricted from flowing in through the higher elevation aperture while the liquid freely flows into the lower elevation aperture. The restrictor may be of a buoyant material to float upward in the well fluid. The restrictor may also be open in response to contact with the casing wall.

摘要： A method and system for downhole treatment and pumping of well fluids enhances the pumping of viscous fluids to the surface. The first step is to separate the oil and water from the well fluid and then channel the oil to a chamber that encloses the motor. The heat from the motor will increase the heat of the crude oil flowing past the motor, thereby lowering the viscosity of the crude oil. The water flows separately past the motor in another passageway, and remixes with the oil. After the oil and water recombine, the treated well fluid has a lower viscosity, and the fluid is then pumped to the surface more efficiently than without treating the oil.
