  • Publication number: 20110100624
    Abstract: A cyclonic strainer for a well intake that provides for improved separation of gas and fluid in naturally flowing wells during mechanical pumping operations. The strainer includes an elongated member having a channel formed longitudinally therein. A plurality of apertures extend through the elongated member angled downwardly into the channel and away from a center of the channel allowing for a better shear between gas and fluids. The angle of the ports causes fluid to be forced in an opposite direction, resulting in gases and fluids shearing more quickly and cleanly, due to kinetic energy. The angle of the ports can be varied to accommodate different conditions in various well environments. In well environments in which gaseous conditions are extreme, it can be desired for the ports to be sloped southwardly or downwardly at a greater angle than for well environments in which gaseous conditions are not as extreme.

  • Publication number: 20110024112
    Abstract: A debris-catching attachment device and method therefor is disclosed. When positioned in wellbore tubing, the device collects solid impurities found in well environments, thereby preventing the solids from settling onto the pump and its components when pumping operations are halted. The device comprises a ring having one of a plurality of brushes and a plurality of wiper segments coupled to a surface of the ring. As fluid is being forced naturally upward or is pumped, it flows past the components of the ring and is caused to rotate or spin in a cyclonic motion. During the first phase of well production, this directs the fluid and solids toward the tubing wall, allowing gas to escape upward. During the second phase of production, solids are caused to move toward the wall of the tubing, allowing any water and oil to move upward to the surface, with the surface tension dragging the solids along the wall of the tubing. The solids may accumulate on the brushes or wiper segments when pumping operations are halted.

  • Patent number: 7878767
    Abstract: There is provided, in one embodiment, a ball valve for regulating the flow of petroleum fluids therethrough. The ball valve is capable of transitioning between an open and a closed position. The ball valve includes in one embodiment a hydraulic piston, containment union, ported stem, containment cage and drag plunger, and is adapted to regulate the flow of fluid northward through the valve. A ball and seat should be positioned above these components, so that the hydraulic piston may extend therethrough. More specifically, during a pump downstroke, fluid enters the drag plunger, moves northward through the containment cage and into the interior of the ported stem, exits the interior of the ported stem and enters a plurality of angled veins, which impart cyclonic motion on fluid passing northward therethrough, assisting in the removal of debris. Also during the downstroke, a pedestal portion of the hydraulic unseats the ball from the seat.

  • Publication number: 20100269928
    Abstract: A valve cage device is adapted for use with a subsurface pump or the like. The valve cage includes a housing and an insert. The insert includes a cradle, a plurality of angled ribs, and a base. In one embodiment, the insert may also include an extended nose region. A ball and seat may be positioned in the valve cage. During pumping operations, the cradle retains the ball when the ball is unseated, thereby allowing fluid to pass freely through channels in the insert and around the ball. This eliminates violent action of the ball, thereby obviating a need for a hard liner to be included in the valve cage. A port in the cradle allows fluid to pass therethrough when the ball has been released from the cradle. The angular configuration of the ribs provides for a more laminar flow of fluid compared with prior art valve cages, thereby providing improved passage of fluid through the valve cage.

  • Publication number: 20100108150
    Abstract: A valve rod guide is adapted to be coupled to the barrel of a subsurface pump or the like. The guide has head, neck, body, and base regions. A plurality of angled flutes are provided on the body, tapering downwardly for preventing solids from reentering the pump barrel after pump operations are ceased and thereby damaging pump components once pump operations are resumed. The interior diameter of the neck includes lower and upper grooves and a plurality of spiral radial grooves extending therebetween. The spiral radial grooves terminate at exit ports. During pump operations, solids are wiped from the valve rod, drawn into the spiral radial grooves, and accumulate in the lower or upper groove during downstroke or upstroke, respectively. During upstroke, the solids are expelled through the exit ports. A hardened insert may be positioned in the head region, providing a durable wear area for the valve rod as well as a tight fit, thereby preventing solids from escaping through a northern end of the guide.

  • Publication number: 20090304526
    Abstract: A pump apparatus includes a gear pump assembly interposed between top and bottom drive gear assemblies, and coupler assemblies interposed between a bottom of the top drive gear assembly and a top of the gear pump assembly, and between a top of the bottom drive gear assembly and a bottom of the gear pump assembly. The drive assemblies rotate a pre-feed auger. A cyclone screen located within a cyclone housing is positioned over a shaft of the pre-feed auger and interposed between a blade of the pre-feed auger and the bottom drive gear assembly. An intake housing is positioned over the blade of the pre-feed auger, and regulates fluid intake into the pump. As fluid is taken into the pump, it is caused to spin by the action of the auger. This causes solids to be separated from the fluid and to be expelled through exhaust ports in the pump apparatus. As a result, fewer solids are permitted to travel northward with the pumped fluid, thereby helping to protect the components of the pump.

  • Publication number: 20080251131
    Abstract: A methods and system detecting water system leaks provides detecting of water leakage having very low flows. Very low flow leaks are detected by detecting drops in a building water system pressure when the water supply source is disabled. The water system is disabled by an electrically controllable valve, which may be turned off in response to a motion detector that detects that no human activity is present in the building. The rate of pressure drop is used to determine the magnitude of the leak, and multiple thresholds can be used to detect slow leaks versus more serious leaks. A humidity detector may also be incorporated in the system to detect abnormal humidity conditions and shut the electrically controllable valve in response. Appliance current consumption can be detected and used to override motion-sensor based shut-off of the valve, so that water-consuming appliances can continue to operate.

  • Patent number: 6905114
    Abstract: A shock absorbing apparatus and method includes a shaft travelling north and south within a tube. The tube is positioned south of a sucker rod. The shaft has a piston head coupled at a south end thereof, which piston head is received in an area of reduced diameter with the shaft. North pores and south pores permit the movement of fluid into and out of the interior of the tube, in response to the northward/southward movement of the piston head. Fluid entering through the pores provides a shock absorbing effect on both the upstroke and the downstroke. The shock absorbing effect on the upstroke can be rapidly eliminated and an upward shock force generated, through the shearing of a shear pin that maintains a bushing in position on the shaft, restricting northward travel of the piston head.
