Abstract: A method for pumping fluid at a wellhead. The invented method will improve liquid removal by eliminating the need to transport liquid produced from a well to containment facilities using trucks or large diameter pipelines capable of accommodating periodic surges of a high volume of fluid. The danger that the liquid will freeze in cold weather is also addressed. The invention removes liquid from the well site through a small diameter pipeline as a continuous flow at a constant flow rate.

Abstract: A mobile drill rig has a drill mast, a carriage mounted to the drill mast for vertical movement, and a vibratory drill head having a sine generator and a rotation mechanism for imparting vibration and rotation to a drill rod string. An elastomeric torsion coupler couples the rotation mechanism to the sine generator to transmit rotational force to the drill rod string while isolating vibrations of the sine generator from the rotation mechanism. Another coupler connects the drill head to the carriage in a manner that allows floating vertical movement of the drill head relative to the carriage while isolating vibrations of the sine generator from the carriage. Elastomeric bumpers limit the vertical movement of the drill head relative to the carriage. Elastomeric spacers located between the rotation mechanism and the sine generator handle the vertical loading and maintain the proper spacing between the sine generator and the rotation mechanism.

Abstract: A method and apparatus for boring a hole in the earth including a drill bit assembly including a fluid-powered impact engine contained within a drillpipe sub between an ordinary drillpipe and a modified conventional rotary drill bit. The impact engine is powered by pressurized drilling fluid delivered via the drillpipe which acts on a piston to charge an energy accumulator, preferably in the form of a spring. Periodically, the pressurized drilling fluid in the impact engine is vented, allowing the energy accumulator to rapidly transfer its stored energy to an impact bit which is slidingly housed in a rotary bit to strike and fracture the formation.

Abstract: A driving device for installing a pipe or casing, without the use of hydraulic or pneumatic means, by capturing the rotational motion of the drill string. The driving device is placed at the top end of the pipe being (42) installed and the drill string (2) passes through the center of the device. The drill string freely rotates, advances or retracts within the driving device, until the driving device is attached (4) to the drill string when required. When the driving device is attached to the drill string, the rotational force of the drill string and any downward force applied to the drill string are captured, and used to install the pipe. The driving device uses the rotation of the drill string to impact a blow to the pipe, driving the pipe downward. The driving device uses any downward force applied to the drill string to maintain downward pressure on the pipe.

Abstract: A drilling machine drills foundation holes known as drilled shafts or bored piles with a drilling tool attached to an end of a kelly. The kelly is rotated with a rotary drive. The rotary drive has a first motor, a final drive gear coupled to the kelly so as to rotate with the kelly and a planetary gear set between the first motor and the final drive gear. A second motor is coupled to the ring gear on the planetary gear set. A clutch can also be connected to the ring gear. The rotary drive allows the drilling tool to be rotated at low drilling speeds and, without stopping rotation or shifting gears, removed from the hole and accelerated to high speeds to discharge spoil. A mid-range is also possible, wherein the drilling tool can process fluids in the hole. Another motor and planetary gear set can be coupled to the final drive gear and to the second motor.

Abstract: A power swivel provides the rotational force to drill consolidated subsurface strata while an unrestricted airflow through the swivel and down a drill string remove cuttings from the borehole. The power swivel is configured to mount on direct push/driven-vibrating equipment, such as a cone penetrometer, to eliminate the need for a conventional drilling rig when a consolidated layer is encountered during direct push/driven-vibrating operations. A drilling nipple and pack-off are provided near the surface to maintain the air flow during drilling and to direct the cuttings to a desired location. Also, a dual-valved air delivery system provides safe, remote-controlled air flow to the swivel.

Abstract: The down hole motor is a self-contained radial drive unit that is driven by a linear input, which can be supplied from various sources. As linear motion is applied to the input of the tool, drive pins on a drive shaft follow a helical path, converting the linear motion into radial motion at the attached mandrel end. This may then be utilized in various activities such as drilling, boring and obstruction removal. This tool may also be used in conjunction with jarring mechanisms in order to create an impact drilling device, or a percussion motor.

Abstract: The invention is a new drill for making micropiles, equipped with a mast on which the head-carrying trolley slides and having at the bottom of the mast two pairs of vices, a lower fixed vice and a upper unscrewing vice. Besides being able to rotate around the drilling axis, the unscrewing vice is able to move along said mast with respect to the lower fixed vice. The advantages are considerable, since it is no longer necessary to dismantle the rod and the covering during the extraction stages.

Abstract: A hammer device has a machine housing (1) with a hammer piston (2) movable to-and-fro. The to-and-fro movement of the hammer piston is controlled by a valve body (6) movable to-and-fro in the machine housing. The valve body, via a channel (7), alternatively connects a drive surface (5) on the hammer piston to a pressure source (8) and to low pressure (9). In order to expedite the actuation of the hammer piston at its rear dead center, the machine housing has a room (10) which is separated from the channel (7) by the hammer piston at the same time that the valve body (6) maintains the pressure from the pressure source (8) on the rear end surface (5) of the hammer piston.

Abstract: A hole groover comprising a pair of grooving bits radially protruding from the surface of a drill rod and connected to swivel upwardly and downwardly near the end of the drill rod where the drill bit is connected. A connecting rod is connected to the inside ends of the groove bits and causes arcuate movement of the grooving bits as it reciprocates. The hole groover further includes a gear box which is connectable to a rotary drilling unit which converts rotational movement of the rotary drill until to reciprocating movement of a lever. The lever is connected to the connecting rod which causes movement of the grooving bits. The device is readily adaptable to be connected to most rotary drill units and the depth and intervals of the grooves can be easily controlled by adjusting the length of the grooving bits and the gear ratios. The device enables grooves to be cut in a wall hole surface, concurrently with the drilling of the hole.
