摘要： A kit for converting an existing wireline retrievable surface controlled subsurface safety valve (170, 270, 370) into a bypass passageway apparatus (100) allowing the injection of production-enhancing fluid into a wellbore while maintaining the operation of the closure member (374). Bypass passageway (280) can extend between upper (260) and lower (275) adapters external to the existing wireline retrievable surface controlled subsurface safety valve (270) to allow fluid injection bypass thereof. Conversion kit can include a tubing string hanger to suspend a velocity tubing string (407, 507), a gas lift valve (475) for gas lift operations, a locking mandrel (220), and/or a spacer tube (240).

摘要： A method for removing fluids from a commingled well comprises positioning a fluid removal system in the well. In addition, the method comprises sealing a first formation from a second formation, shutting in the annulus, and closing off an inner flow passage of a tubing string. Further, the method comprises allowing the pressure of the first and second production zones to build up naturally. Still further, the method comprises flowing a fluid from the first production zone through a first of a plurality of check valves into the inner flow passage, and flowing a fluid from the second production zone through a second of the plurality of check valves into the inner flow passage. Moreover, the method comprises re-opening the inner flow passage of the tubing string and lifting the fluid in the inner flow passage to the surface.

摘要： An apparatus is provided for suction of a secondary fluid into a primary fluid through one or multiple gaps in contact with a venturi. The venturi imparts a high velocity on the primary fluid to flow across a gap in contact with the venturi and draw in the secondary fluid. The apparatus employs a linear venturi with the flow area, or opening, in the form of a narrow ring or narrow rectangle to increase the length of the gap in contact with the venturi. One gap is provided and positioned in contact with one side of the narrow venturi opening, or two gaps are provided having one positioned in contact each side of the narrow venturi opening. The linear venturi is housed in assemblies referred to as “eductors.” Various eductor embodiments are provided including: 1), cylindrical housings with one or multiple concentric linear venturi with openings in the form of narrow rings; 2), rectangular housings with a single rectangular linear venturi with an opening in the form of a narrow rectangle, with multiple rectangular linear venturi with inlets positioned around a primary fluid inlet to flow radially outward through the multiple venturi, with multiple rectangular linear venturi with outlets positioned around a mixing chamber to cause circulation of the flow of fluids; 3), a cylindrical housing with linear venturi with an opening in the form of a narrow ring adapted for inserting into piping; and 4), cylindrical housings with linear venturi with an opening in the form of a wide ring adapted for installation in piping.

摘要： Well pumping of fluids having low hydrostatic pressure is provided through a combination of jet pumping and gas assisted lifting. A jet pump is located in a borehole in a producing zone of a well, and a source of gas is introduced into the fluid returning from the production location. The gas may be injected into the fluid used to operate the jet pump, such that the gas remains compressed until exiting the jet pump, and then provides assistance in lifting the returning fluid.

摘要： A system and method for systematically and economically recovering formation liquids from the bottom of a petroleum well are disclosed. In a preferred embodiment, the system and method are passive in that they utilize the existing formation pressure of the well to remove fluid build-up across the perforations of the well bore in a manner that is completely free from surface control. The system is comprised of strategically placed carrier subs with installed pressure regulating devices. These carrier subs are regularly spaced below the production packer, along the tail pipe section of the production tubing string and facing the perforated intervals of the well bore. The pressure of the trapped formation gas above the accumulating formation liquid is insufficient to remove all of the formation liquid within the entire length of the tubing string 13. However, an open pressure regulating device mounted on the tailpipe section of the tubing string allows a smaller portion of the formation liquid within the tubing string to be produced to the surface using the existing formation pressure. By systematically removing portions of the formation liquid from within the tubing string using the regularly spaced pressure regulating valves, the formation fluid build-up across the perforations is eliminated, and the petroleum well is able to produce at higher rates and for a longer period without intervention.
