  • Publication number: 20220325609
    Abstract: A tubing obstruction removal device comprised of a tubular housing, a valve assembly disposed in an inlet region of the housing, and a vibratory drive disposed in the housing. The valve assembly includes a valve plate and a spring. The valve plate is in fluid communication with a fluid inlet port of the tubular housing and includes a plurality of orifices. The valve plate is oscillatable along a longitudinal axis of the tubular housing between a closed position and an open position. The spring is in contact with the valve plate and is compressible with motion of the valve plate from the closed position to the open position. The vibratory drive is comprised of a turbine in fluid communication with the valve assembly and joined to a rotatable bar asymmetric with respect to a longitudinal axis of the housing and rotatable around the longitudinal axis of the housing.

  • Patent number: 10947083
    Abstract: A coiled tubing unit includes a coiled tubing assembly and a slickline assembly sharing an axis of rotation with the coiled tubing assembly. A shaft of the coiled tubing assembly is received by bearings on a slickline drum of the slickline assembly and extends through an interior of the slickline drum. A swivel joint connection is rotatably affixed on an end of the shaft as it exits the interior of the slickline drum, thus allowing for introduction of fluid or cabling into the shaft and into the coiled tubing. The coiled tubing drum and slickline drum can rotate independently and are powered independently of each other. The coiled tubing and slickline assemblies are preferably affixed to a removable module, the removable module being positioned on a skid having a power unit and appropriate controls.

A shaft of the coiled tubing assembly is received by bearings on a slickline drum of the slickline assembly and extends through an interior of the slickline drum. A swivel joint connection is rotatably affixed on an end of the main shaft as it exits the interior of the slickline drum, thus allowing for introduction of fluid or cabling into the main shaft and into the coiled tubing. The coiled tubing drum and slickline drum can rotate independently and are powered independently of each other. The coiled tubing and slickline assemblies are preferably affixed to a removable module, the removable module being positioned on a skid having a power unit and appropriate controls.

  • Patent number: 9145738
    Abstract: A jetting nozzle for forming boreholes or for cleaning out other tubular formations has a vibration-inducing mechanism that maximizing penetration rates and expands the diameter of the boreholes. The vibration-inducing mechanism can be an internal turbine responsive to the flow of pressurized jetting fluid through the nozzle. The nozzle has forward openings defining a voraxial spray pattern for the forward-directed jetting portion of the fluid exiting the nozzle. The nozzle can also have a pointed end that is adapted to penetrate the formation. The vibration also reduces friction between the fluid supply hose and the borehole being jetted through the formation by the nozzle. A system for forming boreholes with the jetting nozzle and a method of forming boreholes is also disclosed.

  • Patent number: 8813856
    Abstract: A method and apparatus for selectively reciprocating a downhole device in a wellbore relative to an upper portion of production tubing, so that the upper portion of production tubing does not need to be lifted to operate the downhole device. A shift tool between the upper production tubing and the deflector assembly is designed to lift a deflector assembly independently of the upper production tubing. The shift tool is operated by pressurized fluid delivered from the surface, for example with a fluid-delivery device on the end of coiled tubing lowered through the production tubing.

  • Patent number: 8590637
    Abstract: A jetting hose is conveyed downhole retracted on the end of a tubing string (coiled tubing) for jetting lateral boreholes from a main wellbore. The apparatus allows the operator to sense the speed at which the jetting hose and nozzle are penetrating the formation and adjust the coiled tubing feed-in rate accordingly, optimizing both the direction and length of the lateral borehole relative to the main wellbore.
