  • Patent number: 9341046
    Abstract: A method comprising moving a shifting tool in a first direction through a moveable member positioned in a casing of a wellbore, including moving the shifting tool through a shifting tool interface member (STIM) adjacent the moveable member, until the shifting tool is positioned past the moveable member and the STIM. The shifting tool is then moved in a second direction substantially opposite the first direction until the shifting tool and the STIM engage. The shifting tool is then further moved in the second direction, thereby moving the STIM and the moveable member in the second direction, until the STIM substantially simultaneously (1) engages the casing and (2) disengages the shifting tool.

  • Patent number: 8689878
    Abstract: A downhole tool for removing debris from fluid flowing through the downhole tool uses a screen member and wiper member, the wiper member having at least one window disposed through the inner and outer wall surfaces of the wiper member. Either the screen member or the wiper member is rotatable such that rotation of the screen member or the wiper member causes debris disposed on the outer wall surface of the screen member to fall-off the screen member. At least one directional port disposed at either the upper end of the screen member or the upper end of the wiper member causes rotation of the screen member or wiper member when fluid flows through the downhole tool.

  • Publication number: 20080185157
    Abstract: A low drag flotation system for placing screens in horizontal wells is provided which includes a screen exterior to the washpipe to be placed for sand control, and hydraulically actuated valves for trapping air within the washpipe. The air in the washpipe creates a buoyancy force that decreases the drag force of the pipe string in the horizontal well, allowing it to move further down the well under its own weight. As a result, screens can be placed in longer lengths of horizontal wells to maximize oil and gas production.

  • Publication number: 20080073087
    Abstract: An underground porosity reservoir includes substantially impermeable barriers and an aquiclude surrounding a volume of alluvial deposits for storing water within the pore spaces of the alluvial deposits. A conduit positioned below a surface layer of the reservoir includes an interior volume that communicates with the pore spaces of the alluvial deposits. An air vent connects the interior volume of the conduit with atmospheric air above the reservoir and allows air to pass to and from the pore spaces of the reservoir. Ventilation of the porosity reservoir provides pressure-relief during reservoir filling operations (when the incoming water would otherwise cause an increase in air pressure within the reservoir), and further provides a vacuum-break as water is extracted from the reservoir (i.e., air from the conduit enters the pore spaces as the water is extracted).

  • Patent number: 5690173
    Abstract: A method and apparatus for achieving in situ bioremediation of dissolved or dispersed organic contaminants in the groundwater phase at a contaminated site. The apparatus of this invention is configured to be used within an injection well of the type employed with known remediation techniques and enhances the biological treatment of soil contaminants in situ with microbes through achieving optimal levels of oxidizing agents within the soil. As such, the present invention is adapted to be employed in conjunction with conventional remediation systems to treat water-borne contaminants more efficiently. Importantly, the apparatus is also capable of delivering oxidizing agents in a manner that prevents or at least reduces the occurrence of biofouling of the injection and recovery wells.

  • Patent number: 5560427
    Abstract: A method and apparatus for fracturing and propping a fracture interval wherein a workstring is lowered into the wellbore and a fracturing slurry comprised of a fracturing fluid and proppants is flowed down the workstring to a downhole slurry splitter which separates a portion of the fracturing fluid from the slurry and delivers it to the bottom of the fracture interval to initiate and propagate a fracture in the interval. The remaining slurry including the proppants is at the same time delivered to the top of the interval to prop the fracture as it is being formed. Alternate flowpath(s) deliver fracturing fluid and/or slurry to different levels within the interval to by-pass any sand bridges which may be formed during the fracturing operation.

  • Patent number: 5366009
    Abstract: A gravel pack well tool for use in a gravel pack completion which does not require the circulation of fluids during installation. The gravel is first placed or preset within the completion zone and then the well tool having a auger-liner assembly is lowered and rotated into the preset gravel. The liner assembly is comprised of a fluid-permeable linear surrounded by a torque sleeve which transmits torque from a workstring to a nose sub at the leading edge of the liner assembly. The nose sub has a fish-tail bit thereon to assist the downward movement of the liner assembly into the preset gravel and has passages therein for fluid flow therethrough in the event the assembly becomes stuck in the gravel during installation.

  • Patent number: 5261486
    Abstract: A method and apparatus for installing a gravel pack well completion wherein flow of fluid in the well can be effectively blocked and excessive hydrostatic pressure can be isolated from the top of a pre-placed column of gravel while an auger-liner assembly is rotated into the gravel. Basically, gravel is first placed within the zone after which a liner is lowered on a workstring and the liner is augered into the pre-placed gravel. A packer cup and by-pass assembly is coupled into the workstring having cup packers which effectively block flow within the well during installation of the liner. The cups are mounted on a rotatably mounted sleeve so that the workstring can be rotated while the cups are expanded against the well casing. The packer cup and by-pass assembly includes a bypass which can be opened after the liner has been placed so that the workstring can easily be withdrawn from the well.

  • Patent number: 5190108
    Abstract: Biological fouling of water wells is inhibited by replacing the air in the well column with an anoxic gas such as nitrogen to deprive aerobic bacteria of oxygen. The anoxic gas is applied from a cylindrical tank at the surface and through a gas pipe extending from the tank down into the well casing. The well casing is sealed near the top to prevent air infiltration and maintain a positive gas pressure. The anoxic gas is applied at a slightly positive pressure to maintain the well column filled with it and to prevent air penetration. The gas can be supplied to the well column only or to both the well column and the aquifer so that a blanket of gas in the area of the well inhibits air penetration of the water from the unsaturated cover layer above the aquifer.

  • Patent number: 5036920
    Abstract: A method and apparatus for installing a gravel pack completion which does not require the circulation of fluids during installation. The gravel is first placed or preset within the completion zone and then a well completion tool (e.g. a fluid-permeable liner) having an auger blade thereon is lowered and rotated into the present gravel without circulating fluid through the tool. Since the auger blade mechanically displaces the gravel upward as the tool is moved into the preset gravel, there is no need to flow fluid under pressure to "fluidize" the gravel as is required in prior completions of this type.
