  • Patent number: 3995438
    Abstract: A plurality (preferably six) pistons and cylinders are suspended from the swage block a precise distance below the upper edge and actuatable radially from the longitudinal axis of a tubular member for making a new pile with anchor knobs for increased load carrying capacity and pull-out resistance.

  • Patent number: 3981189
    Abstract: Two methods and two steam samplers are disclosed for sampling steam, at any location or depth in a steam injection well for determining the quality of the saturated steam at that location. The samplers each comprise an elongated cylindrical vessel with a tube having openings mounted longitudinally internally of the vessel for forming an annulus between the vessel and the tube for trapping the steam liquid phase and vapor phase, while ejecting the excess liquid phase and steam vapor phase out the bottom of the tube. The tube has a second internally sliding rod for closing the openings and a spring and J-latch with a weight for releasably locking the tubes in closed position at any depth in the well by a sudden downward inertial force for shearing a locking pin and a subsequent upward spring movement to the closed and locked upper position for sealing the steam condensate and vapor in the annulus for recovery at the surface.

  • Patent number: 3973311
    Abstract: A method of manufacturing self-cleaning spring filters and at least two different spring filters are disclosed. One filter formed by the method comprises a helically grooved hollow mandrel with holes in the grooves and a helical spring closely fitted therearound. The pitch of the spring convolutions is opposite to that of the mandrel grooves so that the mandrel provides lateral support to the spring equivalent to that provided by a solid cylindrical bar for maintaining uniform diameter and concentricity of the spring convolutions while eliminating lateral displacement thereof during high load operations. While this one filter is secured at its bottom to the well, a modification requires securing thereof only at its top to the well with a packer.

  • Patent number: 3958649
    Abstract: Two methods and four mechanisms are disclosed for drilling at right angles to a vertical well at any location or depth in the well. The drilling mechanisms each comprises a flexible spring biased telescopic fluid conduit having a turbodrill on the lower end thereof for extending from an opening in the side of an elongated cylindrical housing for drilling at right angles to the well. The flexible spring biased telescopic fluid conduit comprises a plurality of axially aligned spools with cylinders interconnecting the adjacent ends of adjacent spools and with a compression spring in each cylinder between the two adjacent spool ends for permitting flexibility and telescopic action of the fluid conduit while resisting high compression and torque loads.

  • Patent number: 3954610
    Abstract: A method for making transparent an underwater work area covered with cloudy water for servicing an offshore well and a subsurface well servicing and life supporting work chamber for practicing the method comprising a submarine chamber rotatably mounted on a base positioned centrally of a group of wells around the periphery of the base is disclosed. The chamber has a water filter and an ejection nozzle for ejecting clear water from the filter into an underwater cloudy area over a well to be serviced for providing a relatively transparent area of clear water to see through and work in.

  • Patent number: 3947231
    Abstract: A means for lighting a main burner with a new pilot system comprises inserting and utilizing precisely formed restrictive orifices in the gas and air supply lines for providing a gas-air combustible mixture for flowing downstream to an orifice-diffuser pilot for instantaneous lighting thereof and for insuring steady burning with no flame-out when heating high pressure high velocity turbulent air.

  • Patent number: 3937281
    Abstract: One of at least two different spring filters comprises a helically grooved hollow mandrel with holes in the grooves and a helical spring closely fitted therearound. The pitch of the spring convolutions is opposite to that of the mandrel grooves so that the mandrel provides lateral support to the spring equivalent to that provided by a solid cylindrical bar for maintaining uniform diameter and concentricity of the spring convolutions while eliminating lateral displacement thereof during high load operations. While this filter is secured at its bottom to the well, a modification requires securing thereof only at its top to the well with a packer. Further, full width spacers are formed on the spring convolutions for precise separation thereof and for preventing twisting and lateral displacement of the individual convolutions and for prevention of any variation of the gauge between the adjacent helical spring convolutions particularly while under magnified loads.

  • Patent number: 3934469
    Abstract: Two methods and two steam samplers are disclosed for sampling steam, as at the bottom of a steam injection well for determining the quality of the saturated steam just prior to penetrating the formation. The samplers each comprises an elongated cylindrical vessel with a tube having openings extending longitudinally internally of the vessel for forming an annulus between the vessel and the tube for trapping steam liquid phase while ejecting the steam vapor phase. The tube has a second internally sliding tube for closing the openings and a latch for releasably locking the tubes in closed position for sealing the steam liquid phase in the annulus for recovery at the surface. A method for sampling and a method for forming a sampler, as well as two latch combinations are disclosed.
