  • Patent number: 8960324
    Abstract: An automatic drilling system includes a top drive comprising a proximity sensor disposed in a housing thereof. A portion of the top drive is coupled to elevators through load transfer springs such that axial loading applied to the elevators results in relative movement between a link load collar and a load ring. A proximity sensor is mounted such that the relative movement results in a change in signal output thereof. A processor is in signal communication with the proximity sensor and is configured to operate a drive shaft motor. The processor is configured to disable rotation of the motor when the relative movement is indicative of axial loading on the elevators.

  • Patent number: 8602123
    Abstract: The disclosure describes, in part, apparatuses and methods for installing structures (e.g., foundations, footings, anchors, abutments, etc.) at work sites, such as difficult-access work sites. In some instances, a rotating drill assembly is assembled over a target location in order to excavate a radial array of batter-angled shafts associated with the target location in preparation for the installation of a radial array of micropiles. An operator utilizes the rotating drill in combination with a foundation pile schedule/decision matrix to design and install the radial array of batter-angled micropiles. This disclosure also describes techniques for designing, fabricating and installing structural caps to be coupled to the installed radial array batter angled micropiles. These structural caps are lightweight and, thus, more portable to difficult-access sites where they are coupled to the micropiles forming a foundation for structure to be installed at the difficult-access site.

  • Patent number: 7828087
    Abstract: A well drilling apparatus includes multiple, transportable, modular, pre-assembled sections which include a substructure and multiple mast sections. These pre-assembled sections allow for a quicker complete rig-up of the well drilling apparatus at ground level in a horizontal direction, without the use of a crane. Once the assembly has been completed at ground level, the mast is raised to its vertical operating position via mechanisms for raising and lowering dog tails. During transport, the guide rails are built-in to the mast sections and the crown block is attached to the traveling block, thereby facilitating the rigging-up process. The mast may be lowered after the drilling operation has been accomplished without interfering with any blow-out preventer devices that may have been placed on the wellhead while the structure was at its raised operational level.

    Abstract: A guide track system for a tool that can be raised and lowered within a telescoping drilling rig tower is provided. The system includes parallel guide rails mounted on a fixed lower tower section and on a movable upper tower section of the drilling rig tower. The lower and upper guide rails are parallel to one another and overlap one another when the lower tower section is nested with the upper tower section. Guide wheels rotatably attached to the tool can have parallel grooves to roll on the guide rails. The grooves can have sidewalls that flare outward so that they do not scuff against the guide rails as the tool travels up and down within the tower.

  • Patent number: 7717196
    Abstract: In an angle drilling device for introducing or expanding wellbores that are inclined in relation to the horizontal, an angle-adjustable bore rig for a movable feed drive is arranged on a base frame that is movable for example. The bore rig is pivotally connected with the base frame while a connection, for example a link bar, extends between the feed drive and the base frame and has a constant length to effect during travel of the feed drive a change in incline of the bore rig as a consequence of the distance between both pivot points for the bore rig and the point of articulation of the connection.

  • Patent number: 7617888
    Abstract: A pilot tube drive assembly used with an auger boring machine includes a height adjustment mechanism for aligning the pilot tube path of travel with an axis about which an auger of the machine rotates during trenchless installation of underground pipe. A drive mechanism mounted on a drive assembly frame drives the pilot tube to form a pilot hole in the ground for guiding the auger. The height adjustment mechanism may include shorter and taller mounting assemblies which are typically removably mounted on the drive assembly frame. The shorter and taller mounting assemblies may be alternately mounted on the frame at the same location. Typically, the mounting assemblies are removably mounted on spaced rails of an auger boring machine frame via mounting legs which are removably inserted into openings in the spaced rails by an actuating mechanism between the rails.

  • Patent number: 7581600
    Abstract: An improved method of forming a trenchless flow line is provided. The method includes support of the boring tool at each sight relief hole using a hook extending downwardly into the hole so as to overcome the force of gravity on the tool during the pilot hole drilling step. Then, a back reaming tool is connected to the end of the boring tool, and the pipe is connected to the reaming tool, such that the reaming tool reams the pilot hole to a larger diameter ahead of the pipe, which is pulled through the hole with the reaming tool. Drilling fluid is supplied during the reaming process to form a slurry which is pushed ahead of the pipe and upwardly into the sight relief holes, as the pipe is pulled through the reamed hole.
