Tool Movable Exteriorly Of Shaft Patents (Class 175/262)
  • Patent number: 9376869
    Abstract: A system and method for installing casing in a blind horizontal well for blind horizontal directional borings. The system and method may include an example of an offset transmitter sonde assembly that contains an open central passage through which well casing can be inserted, and an example of a drill bit assembly that may be remotely uncoupled from a drill string, leaving the bit in the bore created. Remote uncoupling of the drill bit assembly tends to allow a casing to be installed in the bore while the drill string and bit remain in the bore for support during casing installation. After installation of the casing the drill bit assembly may be uncoupled from the drill string, allowing the drill string to be withdrawn from the bore, with the drill bit assembly remaining in the bore.

  • Patent number: 8813876
    Abstract: An impact dissipation tool for supporting a downhole tool in downhole applications. The tool includes a base and a housing. The tool also includes a carriage located within the housing and coupled to the base, the carriage being movable relative to the housing upon a predetermined impact force. A dissipator disposed inside the housing is collapsible due to the relative movement of the carriage and the housing. The collapse of the dissipator dissipates the impact force transferred to the downhole tool.

  • Patent number: 8201642
    Abstract: Drilling assemblies include a drill bit and a reamer apparatus in which the drill bit is configured to rotate in rotational direction about a longitudinal axis of a drill string and the reamer apparatus is configured to rotate in an opposite rotational direction about the longitudinal axis. Methods of forming a drilling assembly include configuring a drill bit to drill a subterranean formation when rotating in a counter-clockwise direction and configuring a reamer apparatus to ream a wellbore within the subterranean formation when rotating in a clockwise direction. Methods of drilling wellbores in subterranean formations include rotating a drill bit in a first rotational direction about a longitudinal axis of a drill string to drill a wellbore and rotating a reamer apparatus in an opposite rotational direction about the longitudinal axis of the drill string to ream the wellbore.

  • Patent number: 8016053
    Abstract: Disclosed drilling systems offer multiple methods providing access to the open borehole without first tripping the drill string. In some embodiments, a drill bit has a tool port that is blocked by a plug during normal drilling operations. When a tool is deployed through the interior of the drill string, the tool port opens, enabling the tool to enter the borehole beneath the drill string and perform logging or sampling operations. The plug may be attached to the drill bit by a hinge or pivot, or alternatively, the plug may be discarded and a replacement seated in place after the tool is retracted into the drill string. In other embodiments, the drill bit itself is detachable, allowing the bit to be parked in the hole or in a side bore. If desired, the bit can be re-attached by lowering the drill string to the bottom of the hole.

  • Patent number: 8011429
    Abstract: A transport assembly configured to be attached to downhole apparatus has a support assembly configured to be attached to the downhole apparatus and a ground engaging assembly, which may be a roller wheel configured to contact with and move in relation to a surface of a wellbore. The roller wheel may engage with the support assembly so as to provide for their relative rotation. The transport assembly also includes a retaining member disposed between the roller wheel and the support assembly, and the retaining member is operable to resist separation of the roller wheel from the support assembly. The transport assembly is further configured such that, when the transport assembly is in use moving along a wellbore, the roller wheel bears against the retaining member, which in turn bears against the support assembly. The retaining member is a ball-bearing.

  • Patent number: 7445057
    Abstract: A drill head has a domed leading face and carries cutting teeth. A tubular drill string can be used to drive the head into the ground. An off-center aperture communicates with the bore of the string, by means of a connecting passage, which defines an oblique cone. During drilling, a flushing medium can be pumped down the bore and out through the aperture. As the drill string and head are withdrawn, an elongate member can be introduced down the bore, out through the aperture, to be left in the passage drilled by the head. The form of the mouths and connecting passage avoid the elongate member encountering any discontinuities which would prevent it leaving the head. The elongate member could be reinforcing bar for a cast-in-situ pile, or part of a ground loop for a ground heat energy system.

  • Patent number: 4691789
    Abstract: A process for establishing a clear, generally horizontal borehole path in a subterranean formation includes drilling a generally horizontal borehole using a drill pipe, drill bit and an uphole drilling device and lubricating the drill bit and pipe by pumping a mud down the center of the drill pipe in sufficient quantity to carry cuttings, created by the drilling, from the horizontal borehole using a mud capable of creating a cake on the borehole wall. Throughout drilling of the borehole, the total solids content of the efflux is adjusted to preselected levels and recirculated through the drill pipe to continually create the borehole wall cake. After drilling, the drill bit and drill rod are removed and the drilling bit replaced with a casing shoe. Thereafter, the drill pipe is reinserted into the borehole with a liner therein.

  • Patent number: 4651837
    Abstract: A rotary well-drilling bit lowered through a drill string to a special orienting, positioning and aligning sub attached to the bottom of the drill string with the aid of mud pressure with the bit approximately 90.degree. from its normal operating position. The drill bit is prepositioned before entering the drill string and utilizes a drill bit positioning means to properly orient and position the drill bit at the bottom of the borehole. Once properly positioned and oriented, a wireline attached motor turns an assembly shaft which raises the drill bit into its bit receptacle. Removal of the drill bit is accomplished by relowering the wireline attached motor and turning the assembly shaft to loosen the shaft from the drill bit and raising the wireline, wireline motor, assembly shaft and drill bit through the drill string.
