  • Patent number: 9181785
    Abstract: A subterranean pump is delivered on coiled tubing with power and control cables running inside. The pump suction has a tubular inlet that seals in a polished bore in the surrounding tubular. A diverter opens a lateral port and closes entry to the pump suction when the pump is not running and the formation pressure is high enough to bring production to the surface. This configuration prevents the pump from turning while the formation pressure allows production to the surface. If the pump is started it reduces pressure ahead of a movable plug to draw it toward the pump against a spring bias. The lateral ports close and an inline flow path opens to allow the pump to draw through the diverter and discharge into the annular space around the coiled tubing on the way to the surface.

    Abstract: Well pump units for studying, repairing and developing of wells. The proposed well jet system comprises a logging instrument, a movable sealing unit, and a jet pump arranged in a flow string. The latter enables to create a series of different drawdown values in a well under-packer area, and thus to register parameters of the well and a medium pumped out of the well and to easily register a formation pressure restoration curve for the well under-packer area. When testing the formation, a pumping mode may be adjusted by changing pressure of an active working medium supplied to a jet pump nozzle. The provision of a channel for supplying the pumped out medium with a check valve helps avoiding a spontaneous flow of the working medium into the under-packer area. The system reveals increased operational reliability and productivity during the treatment of a productive formation and well testing.

  • Patent number: 8316938
    Abstract: A method and apparatus is provided for diverting a ground water supply source located in a stratum that is hydraulically separated from a hydrocarbon-containing reservoir formation for injection into the reservoir proximate the oil-water interface to enhance the flow rate and production of the hydrocarbons through one or more well bores without pumping the injection water to the earth's surface. An electric submersible pump (ESP) and Y-tool assembly is positioned in the well bore at the level of the ground water supply and water is pumped down the well casing for injection into the formation, e.g., below the hydrocarbon-containing reservoir rock. Suitable seals, packers and cement plugs are provided to isolate the high pressure injection water from the ground water drawn into the first upper portion of the casing.

  • Publication number: 20110278015
    Abstract: An artificial lift system removes reservoir fluids from a wellbore. A gas lift system is disposed in a first tubing string anchored by a packer, and a downhole pump, or alternative plunger lift, may be positioned with a second tubing string. A dual string anchor may be disposed with the first tubing string to limit the movement of the second tubing string. The second tubing string may be removably attached with the dual string anchor with an on-off tool without disturbing the first tubing string. A one-way valve may also be used to allow reservoir fluids to flow into the first tubing string in one direction only. The second tubing string may be positioned within the first tubing string and the injected gas may travel down the annulus between the first and second tubing strings. A bi-flow connector may anchor the second string to the first string and allow reservoir liquids in the casing tubing annulus to pass through the connector to the downhole pump.
