    摘要: It is desirable to prevent the unintended generation of electricity by permanent magnet motors in a submersible pumping system used to recover fluids from a wellbore. A pumping system designed to prevent the unintended generation of electricity includes a pump intake that provides a path for the wellbore fluids to enter the pump. The pumping system further includes a flow control valve assembly connected to the pump. The flow control valve assembly has a sliding sleeve and a valve control mechanism that moves the sliding sleeve between open and closed positions on the intake of the pump.

    摘要: A side pocket mandrel for use within a gas lift system has a central body that includes a central bore and a valve pocket that is offset from the central body. The valve pocket includes a power landing in the valve pocket and configured to provide an electrical connection to the electric gas lift valve and a conductor connected to the power landing and configured to provide electric power to the power landing. The side pocket mandrel further includes a pneumatic gas lift valve installed within the valve pocket and an electric gas lift valve installed within the valve pocket. The electric gas lift valve and pneumatic gas lift valve can be installed or retrieved from the valve pocket using wireline-based tools without removing the side pocket mandrel from the well.

    摘要: A side pocket mandrel is configured for use within a gas lift system deployed in a well that has an annular space surrounding the gas lift system. The side pocket mandrel includes a central body that includes a central bore, a gas lift valve pocket, and a gas lift valve installed within the gas lift valve pocket. The side pocket mandrel may also include a motorized choke valve assembly to selectively cover some or all of an internal tubing port extending between the central bore and the gas lift valve pocket. The side pocket mandrel may also include an automatic closing valve assembly configured to automatically close the gas lift valve port when the gas lift valve is removed from the side pocket mandrel.

    摘要: A method and apparatus for selectively connecting a first fluid communication region to a further fluid communication region are disclosed. The apparatus comprises an elongate housing, locatable in a wellbore, comprising a first end portion associated with a first fluid communication region; a sheath member axially slidable within the housing and biased towards the first end portion via at least one biasing element; and an elongate shuttle member axially slidable within the housing and slidably locatable in a sealed relationship or non-sealed relationship with the sheath member; wherein the biasing element provides a predetermined biasing force that determines a threshold pressure which must be exceeded by a fluid pressure in the first fluid communication region to permit axial movement of the sheath member away from the first fluid communication region or towards a further fluid communication region.

    摘要: A self-orienting casing entry tool, including a mule shoe body having an angled nose terminating the body creating a first relatively longitudinally shorter portion of the body and a second relatively longitudinally longer portion of the body, wherein the first portion of the body is made of a material, the first portion having a density, and the second portion of the body is made of the same material, the second portion configured to exhibit a lesser density. A method for entering a predisposed casing in a deviated borehole including running a tool at the front of a string being run in the borehole, floating the tool into an orientation where the mule shoe body will enter the predisposed casing. A borehole system including a borehole in a subsurface formation, a string in the borehole, and a self-orienting casing entry tool disposed as a part of the string.
