  • Patent number: 9617822
    Abstract: A setting assembly for a packer seal features peripherally mounted rod pistons that abut the seal to be set by advancing the seal relative to a tapered surface. When parts of the seal engage an inner tubular wall before other parts of the seal the continuation of application of hydraulic pressure to the pistons moves parts of the seal that have yet to make contact with the tubular wall further relative to the ramp so that plastic deformation of the seal assembly can occur to allow portions thereof to move radially further outwardly to seal in the region where the radius of the tubular is enlarged. When hydraulic pressure is applied to the pistons in an opposite direction a lock mechanism is defeated and the c-ring or scroll reverts to a smaller shape optionally aided by a garter spring so that the packer can be selectively retrieved.

    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.

    Abstract: Removing water from a subterranean formation entails pumping hydraulic oil from a surface-located hydraulic oil pump through a hydraulic oil line to a downhole downhole pump piston to drive it in a first direction to pump water through a downhole water line to a water chamber of a transfer chamber at the surface. A piston separates the water chamber and an oil chamber and moves to compress the hydraulic oil in the oil chamber of the transfer chamber. The hydraulic oil pump may then pump hydraulic oil into the oil chamber causing the piston to move toward the water chamber, thereby moving water in the downhole water line and resetting the piston in the downhole water pump. A water valve in the downhole water line at the surface may open and release water when the piston in the downhole water pump reaches a predetermined or reset position.

  • Patent number: 8602095
    Abstract: Provided are methods and apparatus for removing oil or natural gas from the ground. In one example, the method includes reforming a fuel source by reaction with water to generate driver gas, and injecting the driver gas into the oil well. The reforming operation can include causing the combustion of a combustible material with ambient oxygen for the release of energy; and heating a reforming reaction fuel and water sources, with the energy released from the combustion of the combustible material, to a temperature above that required for the reforming reaction wherein the fuel and water sources are reformed into driver gas. In one example, the amount of the combustible material combusted is sufficient to result in the release of enough energy to heat an amount of the reforming reaction fuel and water sources to the temperature above that required for the reforming reaction to proceed. The driver gas is used to help extract oil from the ground and especially oil from depleted oil wells.

  • Patent number: 8529772
    Abstract: A method and apparatus are disclosed for separating a multiphase fluid stream that includes a heavier fluid component and a lighter fluid component. The fluid flows along a first helical flowpath with a first pitch. The first helical flowpath is sufficiently long to establish a stabilized rotating fluid flow pattern for the stream. The uniform rotating fluid also flows along a second helical flowpath, the second helical flowpath having a second pitch greater than the first pitch. The lighter fluid is removed from a radially inner region of the second helical flowpath. The method and apparatus are particularly suitable for the separation of oil droplets from water, especially from water for reinjection into a subterranean formation as part of an oil and gas production operation. The method and apparatus are conveniently applied on a modular basis.

  • Patent number: 8424597
    Abstract: Separating gas from liquid down hole in a well by a downhole gas separator, gas is separated and passed to the well annulus and liquid is passed to a submersible pump at a calibrated flow rate at which liquid is vacated from a separation chamber, the length of the separation chamber providing sufficient space for gas separation as the liquid is pumped from the separator. The gas separator, limiting the amount of fluid passed to the separation chamber at less than the pumping rate of the submersible pump, creates a fluid vortex causing the separated liquid to move to the periphery and separated gas to pass near the axial center of the separation chamber. The separated gas passes to the well annulus and the liquid passes to the inlet of the submersible pump.
