  • Patent number: 9376889
    Abstract: A downhole valve assembly operable to control production fluid flow around an obstruction in a production tubing string. The obstruction may be caused by another valve or valve assembly located in the production tubing string, where the valve is closed and blocks flow through the production tubing. The downhole valve assembly comprises a tubular body that includes an axial passage extending through the body and one or more ports extending substantially radially through the body. The downhole valve assembly also includes one or more actuating members operable to move relative to the body. Movement of the actuating members selectively opens the ports such that a fluid flow path through the ports is defined between an annulus region outside of the valve assembly and the axial passage such that the blockage can be bypassed.

  • Patent number: 8973652
    Abstract: The pipe wiper assembly of the present invention assists with wiping the pipe as the pipe is removed from the hole (“tripped out”). The pipe passes through the two pipe apertures of the pipe wiper assembly during the removal. Two upper containment arms adjust between an open position and a closed position within the housing to form the upper pipe aperture. The lower containment lip forms the lower piper aperture. The upper containment arms and lower containment lip partially enclose the housing to prevent the wiper from exiting the wiper storage. The containment arms slideably adjust to eliminate the need for hinges. The removal of the hinges provides for easier storage and transportation of the pipe wiper assembly. The removal of hinges also reduces manufacturing costs of the pipe wiper assembly.

    Abstract: A flute-wiping auger cleaner has a laterally-shearing shackle, an axial track spaced parallel to the auger; and a traveling carriage on the track for supporting the shackle. The shackle includes a series of angularly-staged wiper blades to project into the flute of the auger and centrally stabilize the blades on the turning axis of the auger. The shackle is biased not only to pressure the wipers inwards towards the auger's cylindrical sidewall but also allow the shackle to open slightly against the force of the bias in event a blade cannot dislodge a difficult clump of fouling material in the flute. In that event, the blade is pushed out and then pressured back in as it rides over the difficult-to-dislodge clump. Spinning the auger causes the blades to travel the length of the helical flute while the shackle travels axially on the track.

    Abstract: This device is a pipe wiping apparatus. The pipe wiping structure incorporates a housing and the housing is provided with a central opening to enable the housing to be positioned along the pathway of a pipe string. The pipe string is extended upwardly and passes through the housing. The pipe string is made of a number of drill pipes which are serially connected to extend through the housing so that the external surface can be wiped. As the pipe string passes through the housing, it is exposed to the action of similar wipers which are mounted on multiple actuators where each actuator incorporates a low pressure pneumatic cylinder. The cylinder operates a piston which moves a piston rod which operates a belt crank. This belt crank mechanism rotates an arm to thereby rotate a curving conformed resilient wiper element of sheet material. It is supported on the arm extending radially inwardly toward the pipe. Retraction is permitted to pull the wiper away from the pipe.

  • Patent number: 4457366
    Abstract: A wiper device is provided comprising a container having a central opening through which the well string may pass. A pair of opposed wiper pads disposed in a horizontal attitude are mounted in spaced vertical relationship within the container for longitudinal movement toward each other, to engage the vertical string. A double-acting pneumatic cylinder actuates each pad. Each cylinder is mounted in the plane of the pad, said cylinder being connected at its front end with the rear portion of the wiper pad and being pivotally connected at its rear end with a support member. The front end of the cylinder is thus adapted to rotate in a horizontal plane about its pivot connection, to accommodate transverse movement of the attached wiper pad. The container side walls are spaced from the wiper pad edges to permit such transverse movement to take place. Arrays of anti-friction rollers support each of the pads.

  • Patent number: 4364441
    Abstract: A hole cleaning device which may be attached to the top of an auger or auger extension for rotation therewith includes two diametrically opposed blades arranged to resemble one flight of an auger, the outside diameter of the blades being suitably larger than the hole-digging auger itself. The two blades are secured to a mounting sleeve adapted to be secured to the upper end of the auger tube which supports the auger or to the top auger collar. To the top sides of the two blades are secured two elongated and radially extending deflecting elements, these being arcuately shaped and upstanding. As a hole is being drilled into the soil, the displaced soil is lifted and deposited onto the surface of the ground in an area around the hole. When the hole is drilled to full depth, the cleaning blades engage the soil build up, lifting and throwing it radially outwardly. For slow auger speeds, the loose soil is stacked in an annular pattern spaced from the hole.

  • Patent number: 4284150
    Abstract: A soil sampling device adapted to be mounted on a motor vehicle. The soil sampling device includes a tubular probe which is operated by means of a hydraulic cylinder and piston. A mechanism linking the probe with the piston causes the probe to swing from a horizontal position to a vertical position and then to move vertically downward into the soil. Upon withdraw from the soil the probe is caused to move vertically upward until clear of the soil and then to swing to a horizontal position with the end of the probe adjacent a sample collecting container. A second hydraulic piston and cylinder serves to eject the soil sample from the probe and into the collecting container. The controls for operation of the device are adapted to mounted at the vehicle operator's station.

  • Patent number: 4143720
    Abstract: In a system for obtaining core samples from a submerged bottom a core barrel and holder assembly attached at its upper end to a cable is dropped through the water from a floating vessel, and after the barrel has penetrated the submerged bottom a winch on the vessel is operated to raise the assembly into a guide tube carried by the vessel in an over-water position. An operator on the deck of the vessel swings the barrel through a vertical slot in the guide tube and as the cable is released slowly the barrel is guided to a near horizontal position so that the core sample can be removed from the barrel. The holder tilts within the guide tube during this operation but is prevented from passing through the slot, thereby preventing the assembly from swinging as a result of wave action on the vessel. The system can be used to take samples while the vessel is being propelled through the water and during rough weather.
