  • Publication number: 20120312551
    Abstract: Apparatus for running a casing string into a wellbore features a housing arranged for coupling to the casing string in fluid communication with an interior thereof, a shoe rotatably supported at a lower end of the housing, and a drive mechanism. The drive mechanism features a shaft extending internally along the housing toward the upper end thereof from a connection of the shaft to the shoe, and a ribbon coiling around and along the shaft toward the shoe in a manner radially spaced from the shaft above the connection thereof to the shoe. The ribbon drive rotations of the shaft through action of a fluid on said ribbon under pumping of said fluid through the housing from the casing. The drive mechanism thus employs a simple structure of a rotor assembly spinning within the housing, without requiring an additional stator or housing-carried vanes.

  • Publication number: 20110192614
    Abstract: A well drilling tool has a tubular member connected into a casing string that serves as a drill string. A load shoulder is located within the bore of the tubular member. The load shoulder has a torque transferring portion that extends from a lower terminus to an upper terminus. The load shoulder has an axial force transferring portion that faces upward. A bottom hole assembly is lowered through the casing string and lands on the load shoulder. The bottom hole assembly has a mating profile to the load shoulder so that it will be supported by the load shoulder and will receive torque transferred from the load shoulder.

  • Patent number: 6102119
    Abstract: A method is disclosed for installing a tubular member, having an upper end and a closed lower end, axially into and through an over-pressured region of the earth by using a mandrel to drive the tubular member from near the bottom, which results in a significant section of the tubular member being pulled through the over-pressured region. In another embodiment, a filler material is inserted into at least a portion of the tubular member, and the tubular member is driven from the upper end, with the filler material assisting the progression of the tubular member through the over-pressured region.

  • Patent number: 5351533
    Abstract: The present invention is an improved apparatus and method for measuring downhole flowing and shut-in pressures to determine the condition of the reservoir and the potential of the well as a stimulation candidate. The tool string of the present invention is a novel combination of existing equipment that allows an electronic pressure gauge and shut-in tool to be run into the hole with coiled tubing. The present invention, in most cases, solves the potential problem of having to shut in or kill a flowing well prior to and after performing pressure testing, preventing lost production or potential well damage due to the killing operation. In addition, the present invention provides accuracy over current coiled tubing systems by reducing the effects of wellbore storage on pressure build-up testing.

  • Patent number: 4665980
    Abstract: A granular medium such as gravel is emplaced in the bottom of a well. A well liner is attached to the end of a drill pipe and lowered to the bed of gravel. The drill pipe is then driven at a sonic frequency which may be a resonant frequency of vibration of the vibrating system including the pipe and the liner. A packing seal is provided between the outer wall of the drill pipe and the inner wall of the well casing to prevent the gravel from rising up the casing. The liner is sonically driven so that it penetrates into the gravel medium, the gravel being trapped beneath the seal. The gravel is fluidized by the sonic energy and packed uniformly around the liner to provide a filter for the well effluent. Further, the fluidized granular medium may be highly pressurized by the sonic energy plus the system weight so that it operates to fracture the surrounding formation to engender greater flow from the well.

  • Patent number: 4295526
    Abstract: The method comprises providing an extremely strong and elastic alloy steel ring having a inner diameter substantially smaller than the outer diameter of the pipe to be joined, and an outer diameter much larger than such outer diameter of the pipe. Great axial forces are then employed to insert the pipe ends into the ring until an internal flange is abutted, thus stretching the ring without causing it to exceed its elastic limit. End seals are provided on the flange faces and are pinched off by the pipe ends, so that metal-to-metal contact results. Prior to forcing the pipe ends into the ring, it is mounted in an internal groove in a hinged clasp which aligns the pipe ends.The apparatus comprises the ring, the clasp and the seals, and further comprises the completed joint wherein the ring is under continuous great hoop stress.
