  • Patent number: 9127518
    Abstract: A variable angle drilling machine comprises a frame and a pipe handling system. The pipe handling system is capable of moving from a horizontal to a second orientation and comprises a magazine, a carriage assembly, a shuttle assembly, and a pipe section biasing assembly. The pipe section biasing assembly biases pipe sections towards an open side of the magazine in order for the shuttle assembly to grab a pipe section from the magazine and transport the pipe section to the carriage assembly. The carriage assembly makes up or breaks up a drill string during variable angle boring operations.

  • Publication number: 20150068808
    Abstract: An electric horizontal directional drilling machine. An electric horizontal directional drilling machine is powered by an electric power assembly. The power assembly is made up of a fuel cell and inverter, or multiple fuel cells with synchronized inverters. The electric motor operates hydraulic pumps or works independently to rotate, advance and retract a drill string and downhole tool through the earth and operate various machine functions. Mechanical functions of the drilling machine may also be satisfied through the use of electric rotary actuators (e.g., motors) and linear actuators (e.g., linear motors and solenoids).

  • Publication number: 20090014216
    Abstract: Methods and apparatuses associated with a rotary driven well drilling rig. One method includes providing a rig having: an erectable mast; a head drive unit for rotatably driving drill pipes into a surface; a pumping unit to deliver a fluid through a drill pipe secured to the head drive, the fluid being forced out a bottom end of the drill pipe and up to the surface along the outside of the drill pipe during a borehole drilling operation; and a deck unit pivotally mounted on a turret attached to a set of tracks. This method embodiment includes, while the rig is in a first location, performing a first borehole drilling operation to form a first borehole at a second location; and performing a second borehole drilling operation to form a second borehole at a third location while the rig remains in the first location.

  • Patent number: 7461707
    Abstract: An electric horizontal directional drilling machine. An electric horizontal directional drilling machine is powered by an electric power assembly. The power assembly is made up of a fuel cell and inverter, or multiple fuel cells with synchronized inverters, are used to power an electric motor controller and electric motor. The electric motor operates hydraulic pumps used to advance a drill string and downhole tool through the earth and operate various machine functions. Mechanical functions of the drilling machine may also be satisfied through the use of electric rotary actuators (e.g., motors) and linear actuators (e.g., linear motors and solenoids).
